What is an Android phone lock: One-time fingerprint authentication, face unlock, and the ability to turn off Smart Lock – OREFOLDER

In the power menu of Android smartphones there is an item called “Lockdown” with shutdown and restart. Some of you may have wondered what this is, but have never used it.

If you click on this “lock”, you will not be able to unlock the lock using fingerprint or face authentication only once. It is a security feature.

Unlocking requires a non-biometric method, such as a PIN code or pattern. Once you open it, you will be able to unlock it again using biometric authentication from next time.

This feature is available on Android 9 and above. For Android 9 or Android 10, in SettingsSecurity and locationIf you go to the lock screen settings fromShow insurance optionsThere is an item called If you turn it on, it will appear in the power menu.

On Android 11 and above, if you set a phone lock (such as a code or pattern), it will appear in the power menu. (If it does not appear, try restarting once.)

When to use

Although biometrics are convenient, they say it is less secure than other unlocking methods. It’s easy for people who live together to hack fingerprint authentication using their fingers while they sleep.

Also, if you make your home a “trusted place” with Smart Lock, it will unlock when you’re at home. It is also effective if you have this setting and want to lock it temporarily.

I don’t think you’ll use it often, but it doesn’t hurt to know it’s there.
