APM Forms SSO V2 disable password save prompt

I created an Empty function after the login page, added a new branch with the filter "expr {[mcget -secure {session.logon.last.password}] == "f5-sso-token"}" and forwarded to a Message Box explaining the error, and how to update or delete the entry in the browsers, then forwarding to a Deny_Redirect back to the login page.

Dirty workaround, but prevents accounts being locked out and a few support calls.
