It’s a pretty animation... so nice work on that front.<p>Regarding login in general, people are done with passwords. From a security perspective they are worthless in most situations. From a user perspective, no one wants to make a new one or remember a different one, so they reuse them.<p>The good thing is this greatly simplifies the flow.<p>1) Ask for the email address.
2) check it against your system
2a) user found -> send auth email link
2b) no user, make a new one<p>Done. 2 steps, no passwords, no double path / flow
