When the data security kit is installed
Login when user authentication is enabled
When "User Authentication" in the setting mode (administrator) is
enabled, login is required in the login screen before the machine can be
used. When "A Warning when Login Fails" ("Settings (Administrator)" >
"System Settings" > "Authentication Settings" > "Default Settings") is
enabled, if an incorrect password is entered 3 times in a row, login
operations for the user who entered the incorrect password will be
prohibited for 5 minutes.
For more information, see "About the lockout function" (page 16 of this
manual)
The number of incorrect entries made during login is counted separately
for each user.
The "A Warning when Login Fails" setting is always enabled when the
data security kit installed.
* If a high level of security is set, user authentication will always be
necessary before using any of this device's functions. For more
information, see "Setting a high level of security" (page 24 of this
manual)
