Configuring a strong unlock password for an Android device
To keep an Android device secure, you need to configure the use of a password for which the user is prompted when the device comes out of sleep mode.
You can impose restrictions on the user's activity on the device if the unlock password is weak (for example, lock the device). You can impose restrictions using the Compliance Control component. To do this, in the scan rule settings, you must select the Unlock password is not compliant with security requirements criterion.
On certain Samsung devices running Android 7.0 or later, when the user attempts to configure unsupported methods for unlocking the device (for example, a graphical password), the device may be locked if the following conditions are met: Kaspersky Endpoint Security for Android removal protection is enabled and screen unlock password strength requirements are set. To unlock the device, you must send a special command to the device.
To configure the use of an unlock password:
- In the console tree, in the Managed devices folder, select the administration group to which the Android devices belong.
- In the workspace of the group, select the Policies tab.
- Open the policy properties window by double-clicking any column.
- In the policy Properties window, select the Device Management section.
- If you want the app to check whether an unlock password has been set, select the Require to set screen unlock password check box in the Screen lock section.
If the application detects that no system password has been set on the device, it prompts the user to set it. The password is set according to the parameters defined by the administrator.
- Specify the following options, if required:
- Minimum number of characters
The minimum number of characters in the user password. Possible values: 4 to 16 characters.
The user's password is 4 characters long by default.
On devices running Android 10.0 or later, Kaspersky Endpoint Security resolves the password strength requirements into one of the system values: medium or high.
The values for devices running Android 10.0 or later are determined by the following rules:
- If the password length required is 1 to 4 symbols, then the app prompts the user to set a medium-strength password. It must be either numeric (PIN) with no repeating or ordered (e.g. 1234) sequences, or alphabetic/ alphanumeric. The PIN or password must be at least 4 characters long.
- If the password length required is 5 or more symbols, then the app prompts the user to set a high-strength password. It must be either numeric (PIN) with no repeating or ordered sequences, or alphabetic/ alphanumeric (password). The PIN must be at least 8 digits long; the password must be at least 6 characters long.
- Minimum unlock password requirements (for device owner mode, Android 12 or earlier)
Specifies minimum unlock password requirements. These requirements apply only to new user passwords. The following values are available:
- Numeric
The user can set a password that includes numbers or set any stronger password (for instance, alphabetic or alphanumeric).
This option is selected by default.
- Alphabetic
The user can set a password that includes letters (or other non-number symbols) or set any stronger password (for instance, alphanumeric).
- Alphanumeric
The user can set a password that includes both numbers and letters (or other non-number symbols) or set any stronger complex password.
- Any
The user can set any password.
- Complex
The user must set a complex password according to the specified password properties:
- Minimum number of letters
- Minimum number of digits
- Minimum number of special symbols
- Minimum number of uppercase letters
- Minimum number of lowercase letters
- Minimum number of non-letter characters
- Complex numeric
The user can set a password that includes numbers with no repetitions (e.g. 4444) and no ordered sequences (e.g. 1234, 4321, 2468) or set any stronger complex password.
- Weak biometric
The user can use biometric unlock methods or set a stronger complex password.
This option applies only to devices running Android 12 or later in device owner mode.
- Password lifetime, in days
Specifies the number of days before the password expires. Applying a new value will set the current password lifetime to the new value.
The default value is 0. This means that the password won't expire.
- Number of days to notify before password expires (for device owner mode)
Specifies the number of days to notify the user before the password expires.
The default value is 0. This means that the user won't be notified about password expiration.
This option applies only to devices operating in device owner mode.
- Password history length
Specifies the maximum number of previous user passwords that can't be used as a new password.
The default value is 0. This means that the new user password can match any previous password except the current one.
- Period of inactivity before device locks, in seconds
Specifies the period of inactivity before the device locks. After this period, the device will lock.
The default value is 0. This means that the device won't lock after a certain period.
- Period for unlocking without password, in minutes (for device owner mode, Android 8.0+)
Specifies the period for unlocking the device without a password. During this period, the user can use biometric methods to unlock the screen. After this period, the user can unlock the screen only with a password.
The default value is 0. This means that the user won't be forced to unlock the device with a password after a certain period.
This option applies only to devices running Android 8 or later in device owner mode.
- Allow biometric unlock methods (Android 9+)
If the check box is selected, the use of biometric unlock methods on the mobile device is allowed.
If the check box is cleared, Kaspersky Endpoint Security for Android blocks the use of biometric methods to unlock the screen. The user can unlock the screen only with a password.

On devices running Android 10.0 or later, the use of fingerprints to unlock the screen can be managed for work profiles only.
If the check box is selected, the use of fingerprints on the mobile device is allowed. If the unlock password does not comply with corporate security requirements, the user cannot use a fingerprint scanner to unlock the screen.
If the check box is cleared, Kaspersky Endpoint Security for Android blocks the use of fingerprints to unlock the screen. The user can unlock the screen only with a password. In the Android settings, the option to use fingerprints will be unavailable (Android Settings > Security > Screen lock > Fingerprints).
This check box is available only if the Allow biometric unlock methods (Android 9+) check box is selected.
This check box is selected by default.
