Abstract
A password authentication device includes an authentication processing unit and an output processing unit. The authentication processing unit authenticates a user when an input password that is input matches a predetermined first password. The output processing unit outputs a hint of the first password when a matching rate between a predetermined second password different from the first password and the input password is equal to or greater than a predetermined first threshold value.
Claims10
A password authentication device having a hardware processor executing computer instructions, the computer instructions comprising:
- an authentication processing unit that determines whether an input password that is input by a user matches a setting password of the user, stored in a storage unit, and authenticates the user in accordance with the determination;
- a first storage processing unit that stores, as a first password in the storage unit in association with the user, the input password which has a matching rate with the setting password, which matching rate is less than a second threshold value, among input passwords input by the user during an authentication processing by the authentication processing unit;
- and
- an output processing unit that outputs a hint of the setting password to the user when the authentication processing unit determines that the input password does not match the setting password and the input password matches the first password stored in the storage unit.
