Descrição

Apple has integrated Touch ID with macOS and allows fingerprint use for many common operations. All use of Touch ID requires the presence of a password and the use of that password after every reboot, or when more than 48 hours has elapsed since the device was last unlocked. Touch ID is not a password replacement. The use of Touch ID can, however, make the use of passwords more secure for authorized users with physical access to a Mac. Normal day-to-day work operations can eliminate the use of console password entry unless a reboot is required other than on Monday morning. The infrequency of password screen unlock can enable a more complicated pass phrase that is seldom used. When Touch ID is used it remediates the risk of shoulder surfing (including video surveillance) to capture console credentials. There have been many reported shoulder surfing password captures on iOS devices. Rep...
