django-tokenauth

I solved this for django-tokenauth[1] by making the token short and easy for humans to type in. Depending on how many tokens you have in flight at once, you can use very few digits. [1] https://github.com/skorokithakis/django-tokenauth

I wrote a Django library to do this easily: https://github.com/skorokithakis/django-tokenauth It's the easiest login method by far to deploy, though I think users seem to slightly dislike it.

Why does this need to be a service? I wrote a Django library to do this, all you need is the ability to send email: https://github.com/skorokithakis/django-tokenauth

I like this method so much, that I wrote a Django library for it: https://github.com/skorokithakis/django-tokenauth For a demo, see https://www.eternum.io/ or https://www.pastery.net/.

Funny that you should ask, yesterday I wanted a fast and simple way to do logins for a side project I'm working on and ended up writing a quick Django library that does passwordless authentication over email: https://github.com/skorokithakis/django-tokenauth I would say email is significantly better than a username, as long as the user can change their address. An email is just much easier to remember. Of course, if your identifiers are ever going to be public, you need a username.
