[windows] git clone: Authentication failed for <URL>

Trying to access private corporate tfs. They gave me access by giving appropriate rights to windows user (domain\login).

I'm fine with accessing web interface of tfs, browse repository and stuff.

But when I try to run

 git clone https://tfs.somehostname.com/tfs/somefolder/_git/therepository

It fails with

Cloning into 'therepository'...

fatal: Authentication failed for 'https://tfs.somehostname.com/tfs/somefolder/_git/therepository/'

Tried with home pc without corporate network stuff - same error.

Tried in PowerShell, Git Bash, Clone via VisualStudio - same error.

SSH is closed (gave request timeout).

Web & Git both ask for credentials once (tried deleting in Credentials Manager - asks again, after submitting web is fine, git fails)

Corporate helper tried to help, but all he gave is tfs logs. He says, my username doesn't come with requests (tracked by syncing my attempts timestamps with logs).

This question is related to windows git tfs credentials

The answer is


As the other answers suggest, editing/removing credentials in the Manage Windows Credentials work and does the job. However, you need to do this each time when the password changes or credentials do not work for some work. Using ssh key has been extremely useful for me where I don't have to bother about these again once I'm done creating a ssh-key and adding them on the server repository (github/bitbucket/gitlab).

Generating a new ssh-key

  1. Open Git Bash.

  2. Paste the text below, substituting in your repo's email address. $ ssh-keygen -t rsa -b 4096 -C "[email protected]"

  3. When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

  4. Then you'll be asked to type a secure passphrase. You can type a passphrase, hit enter and type the passphrase again.

Or, Hit enter twice for empty passphrase.

  1. Copy this on the clipboard:

    clip < ~/.ssh/id_rsa.pub

And then add this key into your repo's profile. For e.g, on github->setting->SSH keys -> paste the key that you coppied ad hit add

Ref: https://help.github.com/en/enterprise/2.15/user/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#generating-a-new-ssh-key

You're done once and for all!


I'm facing exactly same error when I'm trying to clone a repository on a brand new machine. I'm using Git bash as my Git client. When I ran Git's command to clone a repository it was not prompting me for user id and password which will be used for authentication. It was a fresh machine where not a single credential was cached by Windows credential manager.

As a last resort, I manually added my credentials in credentials manager.

Go to > Control Panel\User Accounts\Credential Manager > Windows Credentials

Click Add a Windows credential link and then Supply the details as shown in the form below and you're done:

enter image description here

I had put the details as below:

Internet or network address: <gitRepoServerNameOrIPAddress>
User Name: MyCompanysDomainName\MyUserName
Password: MyPassword

Next time you run any Git command targeting a repository set up on above address this manually created credential will be used.

It is also important if you have a git command line you close it and reopen it for changes to be applied.


After trying almost everything on this thread and others, continuing to Google, the only thing that worked for me, in the end, was to start Visual Studio as my AD user via command line:

cd C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE
runas /netonly /user:<comp\name.surname> devenv.exe

Original issue: [1]: https://developercommunity.visualstudio.com/content/problem/304224/git-failed-with-a-fatal-errorauthentication-failed.html

My situation is I'm on a personal machine connecting to a company's internal/local devops server (not cloud-based) that uses AD authorization. I had no issue with TFS, but with git could not get the clone to work (Git failed with a fatal error. Authentication failed for [url]) until I did that.


  1. Go to Control Panel\All Control Panel Items\Credential Manager and select Generic Credentials.
  2. Remove all the credential with your company domain name.
  3. Git clone repository from git bash terminal once again and it will ask for password and username. Insert it again and you are all set!

Rather than escape my password I left it out and was prompted for it, but only when I included the domain name before my username:

git clone https://some-dom-name\[email protected]/tfs/...

Adding username and password has worked for me: For e.g.

https://myUserName:myPassWord@myGitRepositoryAddress/myAuthentificationName/myRepository.git

I had this same issue with my windows 10 machine, I tried many solutions but nor worked until I installed the latest git version. https://git-scm.com/downloads.


I had the same issue when Cloning the repository via Bash/VS Code with "fatal:Authentication failed". I used SSH Key authentication instead to connect my repository following the article: [https://docs.microsoft.com/en-us/azure/devops/repos/git/use-ssh-keys-to-authenticate?view=azure-devops&tabs=current-page][1] I didn't get any errors after with any bash commands!


In my case the error was some old username and password was stored in cache.

So I removed it by going to sourceTree and delete the existing account.

Now for the new clone then it will ask you for the password for the repo. enter image description here


Go to > Control Panel\User Accounts\Credential Manager > Manage Windows Credentials and remove all generic credentials involving Git. This way you're resetting all the credentials; After this, when you clone, you'll be newly and securely asked your username and password instead of Authentication error. Similar logic can be applied for Mac users.

Hope it helps.


In case someone is facing this issue with Azure DevOps, there the fix is very easy, just adding Git credentials to a repository.
