Git Extensions stored wrong credentials [duplicate]
GitExtensions doesn't store any passwords.
They are stored by git or, more exactly, by "git credential manager" that stores them inside windows.
Search for Credential manager* in the start menu and you should find it. Otherwise, it should be in: Control panel => User => Credential manager
Then select the tab Windows credential and you will see keys named like git:xxxx.
