Can't login on github in any way

[verhoog_s2]

Is there any way to log in to Github that works?

I used sourcetree successfully but it now asks to log in.

I tried:

basic login: the accounts dialog doesn't protest, but when pushing my project I get a "remote: Invalid username or password."

OAuth via HTTPS: the accounts dialog doesn't protest, but when pushing my project I get a "remote: Invalid username or password."

OAuth via SSH: I get an error notification that the SSH key could'nt be uploaded. but the message is not shown entirely and when clicking on it, nothing happens (bad UX!!)

How do you connect to Github? 

EDIT: SOLUTION:

Wow, Atlassian has to work on the UX of Sourcetree's login system.

Because counter to any logic, the trick is to NOT use the settings > accounts tab.

This is how I managed to log back in on my github repo:

1 Delete old login trash (that, despite not showing in the accounts tab, still is present!!!) at: ~/Library/Application Support/SourceTree (basically everthing with an emailadress in the file name). more info here.

2 Because I have 2 factor login: create a login token and make sure you add the right permissions https://github.com/settings/tokens

3 Try to push the repo and then Sourcetree finally allows you the opportunity to type in your token.
