I know it's been asked before, but any of the solutions I saw didn't work, I use windows 10 and sourcetree is in version 2.0.10.1
is still asks me for a password, even though I supplied one, I tried deleting the account and log in again, I tried to change the password.
nothing seems to work, it's a shame that this bug is dragging for so long, I saw people ask it about windows 8 and 7!!
