Why passkeys are a step back for personal security: examining account lockout risks, platform lock-in, hardware key limits, and fragile recovery flows.
The best implementation of this I’ve seen has to be Ghost, an open source self-hostable newsletter/patreon thing. They detect what email provider you have and when you enter your email, will display a link to open your inbox. It’s super neat, and I haven’t seen it anywhere else, and I’m also not sure how they do it. For something self-hostable, I’ll definitely take one less attack vector.
A DNS lookup on a domain says who runs the email server for email users on that domain (that’s how email senders figures out how to send you messages), and if that host is a known one then you can just pull the link to show. If you’re self hosting email then a few solutions can be recognized and login shown by guessing that the email software’s default URL pattern is used.

Doesn’t help if you’re not using a huge provider such as Gmail or Hotmail
It worked with ProtonMail

I figured it was something like that, thanks for the explanation!
