In general, keeping track of >1 passwords means giving everyone a password manager and also means you can't integrate with the rest of your endpoint security stuff (like if you use Azure AD, it can check if you are coming from a corporate-owned device and give you different privileges or let you bypass 2FA). There are more creative ways to get people to move to a higher tier rather than locking a essential feature up there. As it is, I can pay for your highest plan or just use PowerApps/Google's equivalent.
