Disallow specific characters from passwords in password policy

I’m wondering if it’s possible to configure a password policy to not allow the user to enter specific characters such as Å,Ä,Ö or special characters?

I can’t seem to find that configuration in the GUI for the policy.
Only configuration for “Minimum special characters”.

I would like a “Maximum special characters” and also the possibility to enter a list of characters that are not allowed.

We can try considering using a custom password dictionary. ISC allows you to create a password dictionary to prevent the use of certain words or patterns in passwords. Here is API please:

Thanks, I’ll try that =)
