As a developer I was a big proponent of 'magic link' style authentication when it was new.
As a user who occasionally runs into this now, I hate it.
Why? I never run into it. I quite like the infinite login sessions, of course, so assuming the only friction is when those expire?
It’s annoying AF for me - I can 1Password into a site with incredibly secure password instantly - but with a magic link I have to find my email client, wait for the email, click it, etc. as a sign in backup it’s nice but as the Main signup it’s a pisser.
