Apple tablet computers run the iPadOS operating system.

The following instructions are applicable to iOS, which is used on iPhones. The interface of iPadOS differs from iOS. For example, the menu may contain more or fewer menu items, they may be named differently, or they may be missing entirely. You can find the relevant settings on an iPad by using the approximate names in equivalent sections of the menu.


How to hide your data from prying eyes

open all
Configure unlock settings

What for: So that only you can unlock your phone.

The safest way to lock your iPhone is to use an alphanumeric password or a fingerprint scanner. A four- or six-digit PIN code is easy to crack, and in some cases a Face ID can be spoofed by a photo or 3D mask.

A strong password complies with the following requirements:

  • Consists of 8 or more characters,
  • Contains lowercase and uppercase letters, numbers, and special characters ($, @, etc.),
  • Is not too simple, such as 12345678 or qwerty,
  • Is not the same as for any other account, including your Apple ID password.
  • Is not an actual word or known phrase,
  • Does not consist of information that strangers could easily find out (such as your name, date of birth, pet's name, or those of your relatives and friends).

To set a password:

  1. Open Settings;
  2. Go to Touch ID & Passcode, or Face ID & Passcode if your device supports Face ID;
  3. Select Turn Passcode On;
  4. Tap Passcode Options;
  5. From the available options, select Custom Alphanumeric Code;
  6. Create a new password;
  7. Confirm it.

Important. Use a strong password even if you decide to sign in with your Touch ID. This strong combination will remain a backup method for unlocking your phone.

To configure sign-in by fingerprint:

  1. Open Settings;
  2. Go to Touch ID & Passcode;
  3. Enter your password;
  4. Tap Add a Fingerprint;
  5. Follow the on-screen instructions;
  6. If you want to use your Touch ID to confirm purchases and sign in to websites, also turn on the following features in this section:
  • iTunes Store and App Store
  • Apple Pay
  • AutoFill Passwords

Set the screen lock time

What for: To prevent strangers from accessing the system if you leave your device unattended.

The system can lock your iPhone when you are not using it. This will prevent strangers from accessing your confidential information in your absence.

To select the amount of time to wait before the device is locked:

  1. Open Settings;
  2. Go to Display & Brightness;
  3. Tap Auto-Lock and select a length of time that is convenient for you.

Important. Do not select the Never option; otherwise anyone will be able to access your personal information on the smartphone if you ever lose your device.

Turn off lock-screen notifications

What for: To not expose your private data.

By default, all notifications are displayed on your device screen even if it is locked. For example, strangers could see text messages containing a one-time code from your bank, or a private message in a social network. To prevent this, disable the display of notifications on your locked screen. To do so:

  1. Open Settings;
  2. Go to the Notifications section;
  3. Tap Show Previews;
  4. Select Never instead of Always;

You can also configure the appearance of notifications on the lock screen and in the Notification Center for specific apps:

  1. In the Notifications section, select the app for which you want to change the appearance of notifications;
  2. Clear the Lock Screen and Notification Center check boxes;
  3. Tap Banner Style and make sure that the parameter is set to Temporary. Otherwise, notifications will be permanently displayed in the upper part of the screen.

Downside: You have to unlock your phone every time you want to read a notification.


How to protect your data

open all
Turn on the Find My iPhone service.

What for: To find your iPhone if it is lost or stolen.

The Find My iPhone service will help you find your smartphone in case it is lost. You can use it to determine the location of your device and sound its alarm, and remotely lock it or wipe its memory. This will protect your data from prying eyes even if you are unable to find your iPhone.

The device search feature works even without Internet access and if location services are turned off. In this case, your lost phone sends a special signal over Bluetooth that is received by other nearby Apple devices. After receiving the signal, these devices send their location to Apple and the company forwards this data to your account. Using this feature, you will be able to see the approximate location of your iPhone in the Find My app.

To turn on the search service:

To turn on the search service:

  1. Open Settings;
  2. Tap your Apple ID;
  3. Open Find My menu;
  4. Go to Find My iPhone;
  5. Turn on the following features:
  • Find My iPhone
  • Enable Offline Finding
  • Send Last Location

You can find or lock a lost device by using the Find My app on any Apple device or at iCloud.com.

Activation Lock is also enabled when the Find My iPhone service is turned on. This feature prevents someone from signing in to your system with a different Apple ID, turning off the Find My iPhone feature, or wiping the memory without password confirmation. That means if your gadget ends up in someone else's hands, they will not be able to use it or sell it, except maybe for spare parts. They will not be able to disable the capability to search for it or lock it.

Please note: If you wipe the memory of your phone, the Apple ID data is also deleted together with your files. In this case, the location of the iPhone will no longer be visible on the map. Therefore, use the option only in extreme cases.

However, when the lock is enabled, your Apple ID data is saved on Apple servers linked to your device ID. This means that even after wiping all data, you can unlock your phone if you find it and enter the user name and password for your Apple ID.

Delete bank card details from Apple Pay

What for: To keep your account credentials and payment information safe.

The Apple Pay service lets you use your phone’s NFC module to pay for purchases . This is very convenient. However, if you link a card to the service, Apple obtains the right to share your location information with the bank, transmit your payment details to third parties, and in some cases transmit your private information. Apple also collects information about transactions and your account, including your card numbers and the approximate totals of purchases and transfers.

To erase this data:

  1. Open Settings;
  2. Go to Wallet & Apple Pay;
  3. Select a card;
  4. Scroll down and tap Delete this card.

Downside: You will not be able to use Apple Pay.

Please note that data deleted from Apple Pay may remain in other storage, such as Safari’s AutoFill list.


How to protect your Apple ID and other accounts

open all
Create a strong password

What for: To prevent your data and devices from being hacked.

An Apple ID account lets you synchronize music, photos, and other data across devices. However, if your account is hacked, criminals will gain access to all this data. In addition, access to your Apple ID will enable someone to remotely lock your device and format its hard drive.

Make sure that your account is protected by a strong password that complies with the following requirements:

  • Consists of 8 or more characters,
  • Contains lowercase and uppercase letters, numbers, and special characters ($, @, etc.),
  • Is not an actual word or known phrase,
  • Is not the same as your passwords for any other accounts,
  • Does not consist of information that strangers could easily find out (such as your name, date of birth, pet's name, or those of your relatives and friends).

To change your Apple ID password on your iPhone:

  1. Open Settings;
  2. Tap your Apple ID;
  3. Go to the Password & Security section;
  4. Click Change password;
  5. Enter your current Apple ID password;
  6. Create a new password and confirm it;
  7. Tap Change or Change password.

You can also change or reset the password for your Apple ID on the Apple website.

Use two-factor authentication for your Apple ID

What for: To prevent your account from being hacked.

You should enable two-factor authentication to improve the protection of your Apple ID. When this is enabled, the system will additionally require a one-time code any time you or someone else attempts to sign in to your account from a new device. In addition, it will send notifications to all the gadgets where you have already signed in to your account. If a different person has entered your user name and password, you can block the sign-in.

If you have already signed in to your Apple ID from a device and then signed out, you will not be prompted for a code the next time you sign in. In iOS 13.4 and later versions, two-factor authentication is automatically enabled when an Apple ID is created. Otherwise you can manually enable it as follows:

  1. Open Settings;
  2. Tap your Apple ID;
  3. Go to the Password & Security section;
  4. Select Turn On Two-Factor Authentication;
  5. Specify the phone number where you want to receive a text message or phone call. This can be your primary number or a backup number. This number is required in case you do not have a trusted device nearby or if it is broken.

There are two ways you can receive a code on a trusted device: View it in a notification (after you tap Allow) or request it:

  1. Open Settings;
  2. Tap your Apple ID;
  3. Go to the Password & Security section;
  4. Tap Get Verification Code.

On a Mac computer:

  1. Open the Apple menu by clicking the Apple emblem in the upper-left corner of the screen;
  2. In the drop-down list, select System Preferences;
  3. Click the Apple ID button in the upper-right corner of the screen;
  4. Go to the Password & Security section;
  5. Click Get Verification Code.

If you do not have a trusted device on hand, you can receive the code in a text message or in an incoming call to the phone number you specified. To do so:

  1. Click Didn't get a verification code;
  2. Choose to have the code sent to your phone number. You will receive a text message or phone call with the code.

Set difficult security questions

What for: To prevent hackers from changing your Apple ID password.

Security questions protect your Apple ID from being hacked. If a hacker wants to take over your account, they can try to reset your password and create a new one. However, the system will require them to answer a few questions to confirm your identity before resetting the password. If they can find these answers in your social networking accounts, they will be able to hack your account despite all of your security measures. We recommend that you set security questions that only you know the answers to.

You can set your security questions on the Apple website:

  1. Visit the Apple ID sign-in page on the Apple website;
  2. Sign in to your Apple ID account;
  3. In the Security section, select Edit;
  4. Add your security questions, then enter the answers to them.

You can change your security questions at any time on this same page.

Automatically save data in iCloud

What for: To safeguard your data.

You can configure your iPhone to automatically save important information in iCloud. If you do so and your device is lost or stolen, you can easily restore your passwords, settings, documents, and photos.

To enable iCloud Backup:

  1. Open Settings;
  2. Tap your Apple ID;
  3. Select the iCloud section;
  4. Turn on iCloud Backup;
  5. If you want to immediately save data on the server, tap Back Up Now.

Downside: With a free account, you cannot upload more than 5GB of data to iCloud.

Check your passwords in Keychain or delete them

What for: To ensure all your accounts are securely protected.

The built-in iCloud Keychain app lets you store and automatically insert account credentials and payment card details. Because of synchronization, this data is available on Mac, iPhone, and iPad.

If you are using identical passwords on different websites, theft or leak of one of them may result in several of your accounts being hacked. You can use the iCloud Keychain service to check whether your passwords match. To do so:

  1. Go to Settings;
  2. Go to the Passwords section;
  3. Enter the password for your Apple ID or use your Touch ID/Face ID;
  4. Select Security Recommendations;
  5. Make sure that the Detect Compromised Passwords parameter is enabled;
  6. You will see a list of resources with duplicate, weak or leaked passwords;
  7. Change the vulnerable passwords:
  8. Click the website name.
  9. Select Change website password.

Although this service is considered secure, there is always a risk that any electronic data can be leaked. To reduce this risk, you can delete your passwords from your account. To do so:

  1. Open Settings;
  2. Tap your Apple ID;
  3. Go to the iCloud section;
  4. Tap Keychain;
  5. Turn off iCloud Keychain;
  6. In the resultant prompt to save or delete the data, select Delete.

Please note that data deleted from iCloud Keychain may remain in other storage, such as the Safari AutoFill list.

Downside: You will have to manually enter your password on websites and in apps each time. You can eliminate this downside by installing a password manager with a reliable data encryption and security system.


How to avoid being hacked

open all
Enable automatic update of iOS

What for: To keep your protection up to date.

Even the most advanced system may contain flaws that enable it to be hacked. iOS developers regularly fix vulnerabilities and add new security functions, so it is important to install the latest patches as soon as possible.

You can configure your system to automatically install updates as they are released. To do so:

  1. Open Settings;
  2. Go to the General section;
  3. Select Software Update;
  4. Tap Automatic Updates;
  5. Turn on Download iOS Updates and Install iOS Updates.

Please note that the device will be updated only if it is connected to Wi-Fi and its battery has at least a 50% charge (or if it is plugged in to a power source).

Set up protection against brute-force password attacks

What for: To protect yourself against a brute-force hack.

If your phone ends up in the hands of criminals, they may attempt to figure out your password by trying all possible variants with the aid of special programs.

To help protect you against such attacks, iOS has a built-in feature for deleting your data after 10 unsuccessful attempts to enter your password. To enable this feature:

  1. Open Settings;
  2. Go to Touch ID & Passcode, or Face ID & Passcode if your device supports Face ID;
  3. Turn on Erase Data.

After 10 unsuccessful attempts, the system will warn you that your data will be erased and will lock the sign-in screen in case the buttons were accidentally pressed or if you made several typos in a row.

Check your third-party keyboard settings

What for: To not be spied on.

You can replace the standard iOS keyboard with a third-party app. By default, a third-party keyboard has no Internet access. This is to prevent the information you enter from being intercepted. However, many apps prompt you to grant them this permission to improve their operation.

You can check whether your keyboard app has permission to access the Internet and revoke permission. To do so:

  1. Open Settings;
  2. Go to the General section;
  3. Select Keyboard;
  4. Choose and tap a third-party keyboard;
  5. Turn off Allow Full Access;
  6. In the opened window, tap Do not allow;
  7. Repeat this with all third-party keyboards.

Restrict the operation of apps when the screen is locked

What for: To prevent your private information from being obtained from a locked device.

Some iOS apps and services allow you to work with the device even while the screen is locked. For example, the Today screen displays activities in your calendar, missed calls, and notifications — very convenient. However, if your phone ends up in the wrong hands, strangers will be able to see the data.

In addition, a skilled hacker can take control of your device or find your hidden information by using specific Siri commands, for example.

To prevent others from interacting with your locked device:

  1. Open Settings;
  2. Go to Touch ID & Passcode, or Face ID & Passcode if your device supports Face ID;
  3. Turn off all features in the Allow Access When Locked section.

Downside: You will not be able to view notifications or use Siri or other features until you unlock your device.

Block other devices from connecting to your locked phone

What for: To prevent hacks that use the Lightning connector.

The Lightning connector can be used to connect various accessories to your iPhone or to transfer files from a computer. To enable devices to exchange data, you must first unlock your smartphone.

You can configure your system to allow the connection even without unlocking your iPhone. This is very convenient. However, if your smartphone is stolen, a criminal can connect hacking equipment to it.

To protect yourself, disable USB access to your locked device. To do so:

  1. Open Settings;
  2. Go to Touch ID & Passcode, or Face ID & Passcode if your device supports Face ID;
  3. Scroll down the page until you get to the Allow Access When Locked section;
  4. Turn off USB accessories.

Note that access through the Lightning connector is blocked an hour after the phone goes to sleep, not immediately.

Downside: You will need to unlock your device each time you want to connect USB accessories to it.

  1. Open Settings;
  2. Go to the Phone section;
  3. Select Blocked Contacts;
  4. Swipe left the name of the caller that you want to remove from the black list;
  5. Tap Unblock.

Enable call and message filtering

What for: To avoid distractions from mass messaging and spam.

To avoid distractions from messages and calls from spammers without having to block each number individually, you can enable a filter. If you do so, you will no longer receive notifications about messages and calls from strangers, or see them in the incoming list. In addition, you will not be able to follow a link from a person's message until you add the sender to your contact list. That helps protect you from phishing scams.

To enable the filter for messages:

  1. Open Settings;
  2. Go to the Messages section;
  3. Turn on Filter Unknown Senders.

To view blocked messages, locate them on the Unknown Senders tab in the Messages app.

To not receive calls from unknown numbers:

  1. Open Settings;
  2. Go to the Phone section;
  3. Turn on Silence Unknown Callers.

After you do so, only people in your contacts will be able to call you. Note that this feature will be disabled for 24 hours if you make an emergency call, so that rescue services can reach you.

Downside: You may miss an important message or call from people who you forgot or did not have time to add to your contacts. In addition, if a friend changes their phone number and tries to notify you from a new SIM card, their messages and calls will also be blocked.

Turn on Do Not Disturb

What for: To block out notifications.

If notifications tend to ruin your concentration, enable Do Not Disturb mode. In this mode, you will not receive sound notifications.


To turn on Do Not Disturb:

  1. Open Settings;
  2. Select Do Not Disturb and enable it.


Important: After you manually enable Do Not Disturb mode, you will not receive sound notifications until you disable it in the settings.

You can configure the system to turn on Do Not Disturb automatically, for example, when you are sleeping. To do so, on the Do Not Disturb screen:

  1. Turn on Scheduled;
  2. Select the time period during which you do not want to receive sound notifications;
  3. You can also configure other settings in this section:
  4. Silence means that you will not receive any sound notifications when the device is locked.
  5. Allow Calls From lets you select from whom you can receive incoming calls even while Do Not Disturb is turned on.
  6. Repeated Calls lets you receive a sound notification about a call if someone calls you twice within three minutes.


How to protect yourself from snooping
