Title: [System Settings] [design] allow PINs of variable length instead of just 4 digits Status in Ubuntu UX bugs: Triaged Status in “ubuntu-system-settings” package in Ubuntu: Confirmed Status in “unity8” package in Ubuntu: New Bug description: Currently when setting a PIN on the device, it must be 4 digits. This is artificially limiting. Other platforms (eg Android) allow longer PINs. It has always been my understanding that we should support Swipe, Passphrase and PIN where Passphrase and PIN can be arbitrarily long. However, once longer PINs are supported, we will have to add an Enter key. Right now, the lockscreen checks the PIN once 4 digits are added so that you don't have to press Enter. I guess this was done for usability, but would be a security issue because an attacker can easily determine the PIN length, which makes it easier to for an attacker to guess the PIN. Eg, if I have a 5 digit PIN set, then an attacker need only type '11111' and know that the PIN is only five characters. Now, a PIN isn't strong to begin with and an automated attack could rather quickly brute force PINs, but we shouldn't make it easier for someone manually trying to guess the PIN. The passphrase lockscreen prompt correctly allows variable length passphrases and requires you to press Enter. I suggest moving the 'X' up t the left of '0' and an Enter symbol to the rigth of '0'.
