I decided to upgrade my Version 1.9 Source Tree to Version 2.3.1.

I did so to find that my cached password was old and needed to be reset.

I navigated to the Options > Authentication Tab.

Source Tree Version 2.3.1 Does Not Display My Saved Password for My GIT Host.

There is no way to update my password using Version 2.3.1.

I tried doing a Git Fetch from the Git Bash thinking this might help.

I was prompted and I was able to access the Git Origin successfully from the Bash but that did nothing to update my cached credential after specifying my new password.

The only way I was able to change my password was to reinstall Version 1.9 where I still could see my cached Host Password.  There I could either Edit or Delete that Credential and be prompted to enter a new password.

Once I did that I was able to open SourceTree 2.3.1 and interact with my Git Origin.

I wasted 2 hours out of my morning playing around with this. 

I am surprised this is not a wide spread issue.

I am not doing anything special here. 

I have not tweaked anything or done anything special with GIT
