Configure the settings as described below.

User Account Lock

Choose whether or not to lock the user account after the user fails to 
login successfully. Specify the number of failed login attempts that 
cause the account locking. You can enter any number from one (1) to 
60. Default is five (5).

When you configure account locking, enter the message to be 
displayed to the user attempting to login. Enter text using 7-bit ASCII 
characters. This message is only displayed when users enter the correct 
passphrase to an account locked by an administrator. This message is 
not shown for accounts locked due to failed login attempts.

When a user account gets locked, an administrator can unlock it on the 
Edit User page in the GUI or using the 

userconfig

 CLI command.

Failed login attempts are tracked by user, regardless of the machine the 
user connects from or the type of connection, such as SSH or HTTP. 
Once the user successfully logs in, the number of failed login attempts 
is reset to zero (0).

When a user account is locked out due to reaching the maximum 
number of failed login attempts, an alert is sent to the administrator. 
The alert is set at the “Info” severity level.

You can also manually lock individual user accounts. For more 
information see 

.

Passphrase Reset

You can choose whether:

Users should be forced to change their passphrases after an 
administrator changes their passphrases. 

Users should be forced to change their passphrases after a 
specified duration. Enter the number of days a passphrase can last 
before users must change it. You can enter any number from one 
(1) to 366. Default is 90. In this case, you can optionally choose:

To display a notification about the upcoming passphrase 
expiration. Enter the number of days before expiration to 
notify users.

To allow a grace period (of specified days) to reset the 
passphrase after the passphrase expiry. Enter the number of 
days. 

If you are setting a grace period, user accounts will be locked 
if the passphrases are not changed within the specified 
duration. If you are not setting a grace period, users can 
change their passphrases any time after the passphrase expiry.

When a user account uses SSH keys instead of a passphrase 
challenge, the Passphrase Reset rules still apply. When a user 
account with SSH keys expires, the user must enter their old 
passphrase or ask an administrator to manually change the 
passphrase to change the keys associated with the account. For 
more information, see
