If you are on the Settings screen, lock the device, then wait until the password expires, then unlock the device, the Settings screen appears without any password prompt. This may cause a backup to be performed, so an attacker can obtain the encrypted data and take it somewhere else for a brute force attack etc. They can also do other things like change the password timeout, etc.
