The Oreilly learning platform does this. Email and password field on the same page and a message under the email field

> Using Single Sign-on (SSO)? Simply enter your company email address and click sign in.

Seems simple enough to me as a user, not sure how most people interact with it though or how many companies A/B test these things.

My company uses an SSO provider with Google Workspace. Most employees have no idea about any of that, they wouldn't know and probably would type their company password there.

The password field disappears if you enter an SSO-compatible email address.

Then you have to either leak a list of each customer to the client to verify there or send each key stroke and consider latency ...

That requires you to teach your users what SSO is. I don't think it's a great UX.
