The problem with magic links is that the secret is sent with each login attempt. It's just like SMS verification codes - an attacker that controls the email address, or the phone number, can log right in. In this case, probably without even resetting a password. Plus, with no way to verify the account owner other than the email address, if the email address is lost or changed, the account's as good as gone.
Also yes they're super annoying for the user too. It's inconvenient and less secure.
Passkeys are awesome, yeah.
As opposed to username/password, where... An attacker that controls the email address can log right in.
Unless you mean to say I should set up 2FA for my CSS theme variable helper website?
Passkeys and OAuth/social login are great, but everyone has an email. And I don't think any mainstream site supports only passkey as an auth method (and no other way).
