Ok, I think I get what you're saying. You mean have a different form input without the password, like how it's done here: https://eu.app.orcasecurity.io/login? I guess that's one way to do it, but it's not really intuitive from a user perspective, since the first thing you see is a password field, and then think you don't have access because you don't have a password. This one comes to mind because I have had to tell people to click the tab for the email only field, not email and password.

I also often see implementations where there's a first step where you have to select how to log in. It's an extra click but very clear (and usually one of the options is some form of SSO where that one click fully logs you in if you already have a session open).
