Android 17 slashes PIN guess attempts from 1,800 to just 20
Android Authority • • general
Key Points:
- Android 17 introduces significantly stricter lock screen rate limits, drastically reducing the number of incorrect PIN or password attempts allowed before imposing lengthy lockouts.
- The hard cap for failed attempts has been lowered from 1,800 over five years in Android 16 to just 20 in Android 17, making unauthorized guessing much more difficult.
- To assist legitimate users, Android 17 includes duplicate-guess detection that ignores repeated incorrect entries of the same PIN or password and provides clear messages explaining the exemption.
- Lockout messages have been improved to show more user-friendly time units (e.g., minutes instead of seconds), and a recovery shortcut is now available on the lock screen for easier account recovery.
- These changes aim to prevent attackers from exploiting common PINs or passwords while balancing security with usability for genuine users.
