Account Credential Validation

[IronKane2]

I'm trying to figure out a way to validate an accounts credentials to see if they have changed their password from the default. I can do this in Active Directory by connecting to a domain with a users credentials. So I'm hoping that there is a way to do this with GSuite.

We use GAPS and at one point we were redirecting user away from the Google password change page and then we turned it back on because of this Distance Learning thing. So we have an unknown mishmash of AD/GSuite password synchronizations that they want me to unscramble.
