Which is the best phone lock

The information portal for safe cell phone use

These instructions for Android devices were created using a Nexus 7 tablet with Android version 5. We have added the text for Android 6 (Samsung Galaxy S5), Android 8 (Sony Xperia XZ1) and Android 10 (Google Pixel 2).

The ways to the correct setting are similar for different Android devices and versions. Different menu items and paths known to us are noted in each case.

Instructions for setting up a lock for iPhones and iPads can be found here.

1. Open device settings

Open the "Settings" app in the mobile phone menu.

Tap on .

2. Call up the item Device security / Lock screen

Next, on Android 5, tap.

Deviating paths:

  • Android 6: Here you will find the point right away
  • Android 8: Navigate as follows:
  • Android 10:
Tap on .

If you have already set a screen lock, you must enter it before continuing.

3. Select screen lock

This is set by default on many devices (it is called on other devices).

This setting does not offer any protection against unauthorized access, because you only have to move your finger across the screen to unlock. Tap or to change the setting

Under the item, for other devices as well, you can see the currently selected lock. Tap the point to change the setting.

4. Set the screen lock

A secure screen lock is a PIN or password of at least eight characters. The combinations should not be easy to guess and should not relate to personal information such as your birthday.

We advise against the method. As studies have shown, such patterns are easy to guess.

More information: Samples and biometric identification

A pattern is more secure than no lock at all. If you would like to use a pattern, we strongly recommend that you make the lines of the pattern invisible, if possible on your device. You can find the setting behind the gear symbol next to the menu item or further down within the menu item.

Some devices also offer biometric options: face recognition, fingerprint and iris scanner. These are significantly more secure than the options and, however, not yet fully convincing. There are always reports that biometric methods can be tricked on smartphones. It also makes it easier to force the screen to unlock.

Tap the method you want to use.

5. Select the PIN for the lock

If you decide to use the PIN or password method, set the PIN or password now. Then tap.

Note: There is no way to recover your PIN or password if you've forgotten the combination. If this happens, you only have the option of resetting the device to factory settings. However, all data is then deleted.

If you decide to use the PIN or password method, define the combination now. Then tap.

You will now be asked to enter your PIN or password again.

Enter your PIN or password again.

6. Set notifications on the lock screen

You may now be asked whether you want notifications to be displayed on the lock screen. Notifications, also known as push messages, are incoming messages, for example about new messenger messages or e-mails.

By default, they come with a preview of the message, which can contain personal information. If you do not want this preview to be visible on your locked display, select the option here. You will then still receive a notification.

You may now be asked whether you want notifications to be displayed on the lock screen. If you are not sure, choose. You can always change this later.

You can also adjust this point independently of the screen lock in your device settings:

  • Android 6:
  • Android 10:

7. Automatic lock when not in use

Now select the period of time after which your device will automatically lock if it is not used. The period should not be too long, we recommend a maximum of five minutes.

Now select the period of time after which your device will automatically lock if it is not used.
  • Android 6: You can find the setting under.
  • Android 10: You will see a small gear icon next to the menu item. Tap on it and choose.

If you would like to deactivate the screen lock in the meantime, navigate to the setting (or) as above and select there. However, we strongly recommend that you always leave the screen lock on for security reasons.
