Add Users from Lock Screen auf Android
Android keeps user management inside Settings by default because adding a profile normally requires the phone to be unlocked first. That single rule stops a stranger who only has lock screen access from creating an account and reaching stored apps or data.
Multi-user households or shared work phones often want a faster path. Android includes a setting that exposes an Add user shortcut directly on the lock screen, letting a second or third person set up their own profile without borrowing an already unlocked device.
Where to turn it on
The option sits inside the multi-user menu: Tap on Settings ➔ Tap on System ➔ Tap on Multiple users ➔ Enable or disable Add users from lock screen. Toggling it on immediately adds the Add user entry to the lock screen user picker.
What changes once it is active
Anyone holding the locked phone can start creating a new profile, though setting it up still requires the usual account steps once inside. Turning the switch off again removes the shortcut and restores the original behavior, where new users can only be added after unlocking the device in Settings.
When to leave it disabled
On a personal phone with sensitive data, keeping this option off is the safer default. It matters most on devices meant to be shared, such as a family tablet or a kiosk-style phone at work.
