How do I clean the history of previous used passwords? The history which is used by passwd or whatever else?

I see:

t-account@dbg-host: ~ $ passwd
Changing password for t-account.
Current password: 
New password: 
Retype new password: 
Password has been already used. Choose another.

I want to clear the list concerning "Password has been already used". How do I do this?

Thank you!

P.S. There is already the same question marked as resolved. How to force password set when a password is not compliant with OS restrictions? My question is NOT how to set/reset/repair and so on.

    Old passwords are generally stored (in a hashed format) in the /etc/security/opasswd file. If you would like to clear them, simply blank the file. – matigo Oct 17 '22 at 06:33

    See also pam_pwhistory on how this is setup, – Rinzwind Oct 17 '22 at 06:55
