file outside of your source tree to avoid inadvertently sharing your client credentials. When I open the private key on the remote server this is the structure (obviously longer & i've changed it for security purposes. This OAuth 2.0 flow is specifically for user authorization. I have Pagent installed but unsure what to do from here? Any ideas. Your SSH agent (Pageant) is running but the server still rejected your connection. When I try to check out via SourceTree it says the following :- SSH Authentication Failed The issue I am having is basically trying to clone this same git repo to my local Windows desktop through a common git client like SourceTree. $ ssh-keygen -t rsa generates as you would expect the two files within my. I can SSH into this using PuTTy and have used the following command to generate the keys (its a Unix based server). Until Sourcetree is updated to include a later version of it's embedded version of Git (2.26.2 is several releases behind now), I recommend installing Git for Windows standalone, and then set Sourcetools to use the "system version" of Git.I am trying to clone a git repo that is currently configured using SSH public/private keys rather than passwords. GCM Core supports OAuth-based authentication which is the requirement from GitHub now. GitHub recently () changed their authentication mechanisms to remove username/password-based authentication, that GCM4Windows used. This explains why you're seeing the older GCM4Windows prompts, and not GCM Core.Īs to why the older GCM4Windows no longer works with GitHub. The latest embedded version used by Sourcetools appears to be Git for Windows 2.26.2, which only includes the older, and now deprecated Git Credential Manager for Windows, not GCM Core. nothing changed: my github password didnt change, I didnt even touch my git, nor sourcetree. Is it the embedded version, or the system version? Why did github authentication suddenly stop working. Which version of Git is being used by Sourcetools? Hi you open Sourcetools and go to: Tools > Options > Git, and scroll down to the "Git Version" section. The new GCM (GCM Core, this project) supports the new authentication mechanism GitHub now require, however Sourcetree isn't using it.Ĭan you please set the following environment variables, restart Sourcetree, and then upload the resulting log file?

If that's the case, then the reason is that GitHub has removed the username/password-based authentication the older GCM for Windows used to use to create authentication tokens (see here). I assume that these are images of authentication prompts you're getting whilst using SourceTree, and that entering username/password(/2FA code) in these no longer works? Something went wrong in your reply of images with GitHub - I cannot see them. That error message comes from GCM for Windows: Then I reran the wizard and chose to download and install the embedded packages. It looks like Sourcetree is using an old version of GCM (GCM for Windows). Possible cause: proxy settings (as in this thread) setup steps, with Git disabled (as in here) When SourceTree started for the first time, I skipped setting up Git & Mercurial in the wizard. Logon failed, use ctrl+c to cancel basic credential prompt. no-optional-locks push -v -tags -set-upstream GitHub_Git_Test After login success, you can run git pull well for you. git pull fatal: Authentication failed for repo url/ Apparently, updating my domain credentials also broke my Git credentials ' As a security precaution, GitHub automatically removes personal access tokens that havent been used in a year.

It will require you to enter your Username & Password. git config -system -unset credential.helper. Open Cmd, run with mode Run As Administrator. Git -c diff.mnemonicprefix=false -c core.quotepath=false Because you change the password so you need to re-login into Gitlab. This is what I get from Sourcetree when I try to push to To use Sourcetree, because that gives me much better visibility of branchesĪnd commits.
