Getting “fatal: Authentication failed” -error when sending git commands in Windows 10

Question

After updating domain password, accessing git-repo is no longer possible. VS Code and Source Tree as well as Visual Studio are returning the following error message on pull, pus

Answer 1

I have experience a similar issue with Windows 10 and here's how I have solved it:

1. From Windows Search, type Credential Manager:

2. Open Credential Manager, and navigate to Windows Credential Tab:

3. You should see an entry for git credentials in Windows Credential Manager:

Here is the root cause, this git credentials is locally cached/saved to your local computer, and since we have changed our Active Directory password, it is currently out of synch.

4. Click Edit, and change this to your new/changed Active Directory password (this password has to match your new/changed Active Directory password) :

Note: This is for using git with https only, not for SSH: https://docs.github.com/en/free-pro-team@latest/github/using-git/which-remote-url-should-i-use

5. Save, it should work (does not require terminal or machine restart).

Lastly, if you do not have access to Credentials Manager (due to admin/security policy), you can force git to prompt for password by do a git pull from the specific repo by using username based repo url, e.g.

git pull https://{yourgitusername}@{gitrepo}.git

Note that, this is repo specific so you will have to do this each repo.

Good luck.
