Why the fuck do we log in with a username?!

The user already entered her email address, she doesn't want to remember a username which doesn't mean anything to her. Let's log in with an email address and avoid having to remember something else. This leads to confusing.

Why not permits the two? Login with username or email adress?

We can but... do we really need a username?

We use it as a slug for the url & as a base for the jabberid. We, maybe, could auto-generate one.

@jbpasquier : It is used anywhere else?

On mockup yes, on left menu & few other places.

Yes we need a username for the chat, but also for other uses.

I guess allowing to login with both is the right UX then

Quick question though: is there anything preventing a user to adopt an email as a login? I'm thinking about the very unlikely event where user A with email a@a.tld adopts b@b.tld as a login whereas there is an actual user B with email b@b.tld in the userbase. Does someone knows how to handle that?

@christophehenry : Good catch.

I see two solutions:

1. preventing @ as a possible character within usernames
2. checking unicity or usernames against both email and username fields

What do you think is the best?

I looked into it yesterday afternoon. Solution is not right. Nothing prevents user A to set b@b.tld as a username and then user B to register with b@b.tld as an email. Solution 1 seems to be the way to go.

Fyi, there is already an implementation of that in Django. I'm not sure how they dealt with this issue, but it might be worth looking into it. It doesn't seem major to me at this time though.

There's indeed a username validator in Django but it allows the @ character.

No my point was that there are modules that enable login through email in Django
