faillock: List login failures of all users.
$ sudo faillock
try on your machine
The "sudo faillock" command is used on Linux systems to manage the faillock feature, which is designed to enhance the security of user accounts by locking them after a certain number of failed login attempts.
When executed with sudo (superuser do), which grants administrative privileges, the command allows the user to view and modify the faillock settings.
Some of the commonly used options with the "sudo faillock" command are:
- "sudo faillock --list": This displays a list of user accounts and their corresponding faillock status, including the number of failed attempts and the lock status (locked or unlocked).
- "sudo faillock --user [username] --reset": This resets the faillock status for a specific user, removing any lock that may be present and resetting the failed attempt counter.
- "sudo faillock --user [username] --unlock": This unlocks the account for a specific user, allowing them to attempt login again even if the maximum failed attempt threshold has been reached.
- "sudo faillock --user [username] --lock": This manually locks the account for a specific user, preventing them from logging in even if the maximum failed attempt threshold has not been reached yet.
These commands provide administrators with the ability to manage user account lockouts and reset the faillock status for troubleshooting purposes or to ensure account security.
