Password validity term

Hi community,

any idea on how to update the Password validity term?

Since some version it seems the default was changed from 0 to 90 (unlike what is explained here: https://academy.creatio.com/docs/user/setup_and_administration/user_and…) and now all users in a recent implementation have a validity term.

If I change the sytem setting to 0 it does not update the validity for existing users.

How can I update existing users?

Thanks,

Luis
