I have always felt like this method sounds good, but is just annoying to do. I want to login fast, usually with passwords that autofill from lastpass or similar app.

Maybe if the information on the site was sensitive it would be worth it, but this is too much for just any random app.

This sounds like the least user-friendly option available and a real obstruction, especially if using the application on a mobile device.

Plus the whole thing becomes unsecure if users start forwarding the email to others without thinking of the implications.

I was debating including that option :P

I've just never actually seen anyone else do it.For some reason, it feels 100x more complicated than checking my SMS app for an SMS code when in reality its not that different.
