There are several ways to unlock your phone. In some cases (such as if you are asleep when using public transport), password unlock is more secure than other unlock methods. When Lockdown mode is enabled, you will only be able to unlock your phone using your lock screen password. Other unlock methods will be temporarily disabled.

You must set a lock screen password to use this feature.

1. Go to Settings > Biometrics & password > Secure lock settings, and enable Show Lockdown option.

2. Press and hold the Power button until the Lockdown option is displayed on the screen.

3. Touch Lockdown and follow the onscreen instructions to enable Lockdown mode. Once Lockdown mode is enabled, your phone can only be unlocked using the lock screen password.

4. Lockdown mode is automatically disabled when you unlock your phone. You can use other unlock methods as usual the next time you unlock your phone.

   If you need to re-enable Lockdown mode, press and hold the Power button and touch the Lockdown option again.
