Sending link to e-mail is exactly as dependent on third party as OAuth.

Non-power users (11 yo kids) maybe don't always have their inbox open/session active.

Best case scenario with one e-mail entry for multiple devices stand in conflict with link only being usable once.

Don't get me wrong, I think passwords are horrible but this post was just made in too much of a hurry.

Interesting topic!
