Ask HN: Any obvious disadvantages to password-less, email-only login?
An idea suggested several times here on HN is the idea of password-less logins: You enter your email address and receive an email with a unique link (valid for an hour or so) which, when clicked, will log you in and allow you to stay logged in for e.g. two months.
This would not work for really sensitive stuff (e.g. banking) where you need to log in each time you visit the site, but for normal sites it's really user-friendly.
My question is: Are the any disadvantages to this model? The only one I can think of is the situation where you've deleted your old email address and some time after that have to log in to a website that uses password-less login. But that is probably a rare occurance and could be fixed by contacting support.
