Sign up with otp to email

Hi, I’m trying to understand if universal login supports passwordless registration with otp to e-mail or sms. On the site, from what i understand, it is about login and not about registration. I would appreciate an explanation of this and whether the process will allow user to choose registration with otp to email or with email and password. which additional fields must be filled in when registering with otp? If you have screenshots it would be very helpful
Thank you!
