How to NOT remember a password ?

[Adrien Baur]

I'm sometimes pushing  things onto a personal remote github from a computer at work, so I don't want sourcetree to remember my credentialfor this specific remote. I'd like for it to require a login either everytime I push, or everytime I start sourcetree.

The way I works right now is :
Every other remote I work on are on bitbucket, so my sourcetree doesn't have any Github account configured. When I try to push for the first time I'll have to login throught this window, but I'll still have to manually delete the saved password when I quit :

Hi, to this day I still don't have any clue about how to make an authentication temporary in sourcetree.
