I'm wondering if you can help with this particular case. My university has a login system that it uses across most of its services and domains. I've added websites as need to the one 1P entry I have for the login and it works great. However, for their Gsuite, though the password is synced with the main login system (meaning I cannot change the Gsuite password itself), the username is different. I've just dealt with this by having the Gsuite login be separate from the university one, but this causes Watchtower to flag the accounts with duplicate passwords. I've been going through trying to address any Watchtower issues, but wasn't sure how to resolve this one.
