What happens when I update the password security level in my security settings?
When you increase the security level for passwords on your account, all passwords set with a lower security level will be set to expire in 5 days. The results of this change will be different for end users than it will be for admins and agents.
The next time an end user signs in, they will be prompted to change their passwords to comply with the new security level. End users will not receive any emails notifying them of the change.
Agents and administrators on the other hand will receive email notifications three days before a password expires, as well as on the day it expires.
