I really dislike these "magic links" as a login procedure as you always have to switch between apps instead of just filling login / 2FA with your password manager. SMS is even worse as it's also insecure.

As an additional option, I can see the benefit for people who live in their Gmail app and don't have a password manager.

If you log in only by the code or magic link, it's not 2FA because there's only one factor

Passkeys are even better since you don't have to pull out your phone or switch to email to grab a code. It just logs you in.

Also for old people, its impossible to fall for a phishing page using Passkeys. Unlike auth codes where you can type the code in to a fake login page.
