Protect the app with a PIN
Enable or disable the four-digit local app lock.
Turn on App Lock
- 1
Open Security.
Choose Settings → Security and turn on App Lock.
- 2
Set a four-digit PIN.
Use the number pad to enter a PIN you can remember.
- 3
Confirm the PIN.
Enter the same four digits again. If they do not match, repeat the setup.
- 4
Check the lock.
After the app locks, use your PIN on the unlock screen. Use backspace on the number pad to correct a digit before completing the entry.
Disable App Lock
- 1
Open Security again.
While the app is unlocked, switch App Lock off.
- 2
Enter the current PIN.
The app verifies it before disabling the lock. A wrong PIN leaves the lock enabled.
If you cannot unlock the app
Check that you are using the local four-digit app PIN. It is separate from any future online account credentials or Google Play purchase.
The current screen has no email-based PIN reset. Contact support before clearing app storage or reinstalling, because doing so can remove local records. A website support request does not unlock the app automatically.
