<Security Settings>

You can specify the settings related to the user authentication function, password, and encryption.

<Prohibit Authentication Using Department ID and PIN>

Select whether to prohibit authentication with a Department ID and PIN when operating from the printer/scanner. If <On> is selected, authentication with System Manager ID and PIN is also prohibited when operating from a device management software.


Jobs that are restricted by this setting are forcibly canceled on the machine.

<Lockout Settings>

Select whether to block users from logging in for a specified period of time after a certain number of consecutive invalid login attempts. This setting does not apply to authentication with a Department ID or PIN, or authentication for the Mail Box.


Users may be blocked from logging in before a specified number of consecutive invalid login attempts if login operations are performed on Windows or other operating systems, or from applications that use FTP, IPP, SNMPv3, SMB, or WebDAV.

<Prohibit Caching of Authentication Password>

Select whether to prohibit caching of a password that is entered at login.

<Display Warning When Default Password Is in Use>

Select whether to display the screen for changing the password when the Administrator logs in to the machine using the default user name and password.


If the password has expired, the screen for changing the password appears, regardless of this setting.

<Allow Use of Default Password for Remote Access>

Select whether to allow the default password to be used when logging in from the Remote UI.

<Minimum Length Settings>

You can set the minimum number of characters required when registering a password to prevent the simplification of passwords. When a password length is set, a user cannot be registered with a blank password.


This setting applies to personal authentication management, not to Department ID and PIN.

<Validity Period Settings>

You can set a password expiration period to force users to periodically change their password, in order to prevent the simplification of passwords.

This setting applies to functions such as IPSec, TLS, Kerberos, S/MIME, wireless LAN, and SNMPv3. The machine may not be able to communicate with devices that only support weak encryption. Even if the use of weak encryption is restricted, it may be allowed depending on the certificate (root certificate). For information on the algorithms prohibited when this setting is set to <On>, see Specifications.
