The credcheck PostgreSQL extension provides few general credential checks, which will be evaluated during the user creation, during the password change and user renaming. By using this extension, we can define a set of rules:
allow a specific set of credentials
reject a certain type of credentials
deny password that can be easily cracked
enforce use of an expiration date with a minimum of day for a password
define a password reuse policy
define the number of authentication failure allowed before a user is banned
define a delay on authentication failures
Release 2.8 has been published, it adds the compatibility with PostgreSQL 17 and shows current credcheck settings in error messageis.
Upgrade require a PostgreSQL restart to reload the credcheck library.
