A secure Android phone is a healthy Android phone. If you’re like me, the primary line of defense for your phone is a PIN. Sure, you may also use your phone’s fingerprint sensor or face unlock, but it’s your PIN or password that’s ultimately keeping your data secure.
PINs work the same on all Android phones: you enter the correct PIN to unlock your phone, and if you enter the wrong one multiple times, you’re temporarily locked out. And as we all know, the longer the PIN, the better.
