Image forming apparatus and determination method in processing apparatus for determining whether authentication information satisfies authentication requirement

1. An image forming apparatus, comprising:

one or more controllers; and

a memory storing one or more computer-readable instructions and authentication information of a plurality of users, wherein

the one or more controllers are configured to execute the one or more computer-readable instructions stored in the memory to:

set, for each user of the plurality of users, an authentication requirement for the authentication information of the user;

authenticate the user based on the authentication information of the user; and

perform a determination as to whether the authentication information of the user being authenticated satisfies the authentication requirement corresponding to the user,

set a time for the determination,

perform the determination at a time set as the time for the determination,

determine whether to perform the determination at a time of login,

disallow, in a case that the determination is performed at the time of login, the user to log in when the authentication information of the user being authenticated does not satisfy the authentication requirement corresponding to the user at the time of login,

determine whether to perform the determination according to an authentication method, and

omit performing, in a case that the determination is performed at the time of login, the determination for the user when a user being authenticated uses the authentication method without the determination.

2. The image forming apparatus according to claim 1 , wherein

the one or more controllers are further configured to configure a setting according to an authority.

3. The image forming apparatus according to claim 2 , wherein

the authority is an administrator or a general user, and

the one or more controllers are further configured to:

set a user or a group of the plurality of users, whose authority is set to the general user, subject to performing the determination, and

omit performing the determination when a user being authenticated is a user other than the user subjected to performing the determination or is a user not belonging to the group subjected to the determination.

4. The image forming apparatus according to claim 1 , wherein

the one or more controllers are further configured to:

determine whether to perform the determination according to a function, and

omit performing the determination when a user being authenticated does not use the function subjected to performing the determination.

5. An image forming apparatus, comprising:

one or more controllers; and

a memory stores one or more computer-readable instructions and authentication information of a plurality of users, wherein

the one or more controllers are configured to execute the one or more computer-readable instructions stored in the memory to:

set, for each user of the plurality of users, an authentication requirement for the authentication information of the user,

authenticate the user based on the authentication information of the user,

perform determination as to whether the authentication information of the user being authenticated satisfies the authentication requirement corresponding to the user,

set a time for the determination,

perform the determination at a time set as the time for the determination,

determine whether to perform the determination at a time of changing the authentication information after changing the authentication requirement, and

display, in a case that the determination is performed at the time of changing the authentication information, a message urging input of the changed authentication information again when changed authentication information of the user for which the authentication information is changed does not satisfy the authentication requirement corresponding to the user.

6. A determination method in a processing apparatus, comprising:

storing authentication information of a plurality of users;

setting, for each user of the plurality of users, an authentication requirement for the authentication information of the user;

authenticating the user based on the authentication information of the user;

performing determination as to whether the authentication information of the user being authenticated satisfies the authentication requirement corresponding to the user;

setting a time for the determination;

performing the determination at a time set as the time for the determination;

determining whether to perform the determination at a time of login;

disallowing, in a case that the determination is performed at the time of login, the user to log in when the authentication information of the user being authenticated does not satisfy the authentication requirement corresponding to the user at the time of login;

determining whether to perform the determination according to an authentication method; and

omitting performing, in a case that the determination is performed at the time of login, the determination for the user when a user being authenticated uses the authentication method without the determination.
