App lock (PIN)
Lock the app with a 4-digit PIN and hide message text in notifications.
If you share your phone with others, you can lock ARWY with a 4-digit PIN. The PIN is separate from your account password and only works on that phone.
Turning the lock on
- Open Settings › Security.
- Under APP LOCK, turn on App lock (PIN).
- Enter a 4-digit PIN, then enter it again.
From now on, the PIN is asked whenever you open the app.
Options
- Ask when returning from background: choose when the PIN is asked after you switch to another app and come back: Immediately, After 1 minute or After 5 minutes.
- Hide content in notifications: while the lock is on, notifications don't show message text, only something general like "New message". Tapping the notification still takes you to the right place.
- Change PIN: to set a new PIN.
Forgot your PIN?
- On the lock screen, tap I forgot my PIN.
- Tap Sign in again. Your PIN is deleted and you're signed out.
- Sign back in to your account. No PIN is asked; you can set a new one in Settings › Security if you like.
Good to know
- After 5 wrong PINs, you need to wait 30 seconds.
- Logging out deletes your PIN.
- App lock is only in the Android app, not on the web.
- To protect your account password, see Changing your password.
