Github Issue: Microsoft Visual Studio we could not add the account error writing credentials into windowscredentialstore. Function: credwrite, Win32ErrorCode: 8.

Whenever I try adding a Github account to make a Github repository, I get this error:

Microsoft Visual Studio we could not add the account error writing credentials into windowscredentialstore. Function: credwrite, Win32ErrorCode: 8.

I tried to delete C:\Users\USER\AppData\Local.IdentityService. But it doesn't seem the credentials are stored here as all my accounts remained after staring Visual Studio.

Hello, which version of Visual Studio are you using? Do you install a helper called “Git Credential Manager for Windows”?
Did this issue occur when following the steps below?

I'm getting the same error. Running Visual Studio Community 2022, v. 17.2.5. Error happens from File → Account Settings, then +Add → GitHub/GitHub Account then selecting GitHub and Sign in with your browser. I get a success screen in the browser, but then get the error message attached above by the OP. I also get the same result and same error if I try Git → Create Git Repository then Account → Sign in... → Add an Account → GitHub/GitHub Account and then selecting GitHub and Sign in with your browser.

Error seems to be related to the Windows Credential Store being out of memory.

Hi Anna,

I am using Visual Studio Community 2022 (64 bit) Version 17.2.3.

I have installed 'Git Credential Manager for Windows' but only after others having similar issues posted to do so. I can't figure out how to make it work and reset the credentials like they say however. The problem existed before I installed this and still exists after.

The helper “Git Credential Manager for Windows” is no longer being maintained and is replaced by GCM Core.
Please try to manually install GCM Core.
For more details, please refer to the link: https://github.com/Microsoft/Git-Credential-Manager-for-Windows.

By the way, the error is more related to Git Credential Store, I suggest you can also report it in GitHub-GitCredentialManger.

Maybe this will be useful to someone (although an important detail is missing....): I had this same issue and for me (using W11) it was resolved by removing one of the 'Generic Credentials' under 'Windows Credentials' within the 'Credential Manager'. Which one... I'm afraid I didn't pay enough attention at the time because I was trying many things and the specific credential escapes me. But certainly one of the GitHub related ones.

It may however be due to storage because the Error Code 8 appears to be referencing inadequate storage space.

All the same; I found this very issue with Visual Studio Community not associating with my GitHub account and issuing the exact same error was directly solved by addressing the Windows Credential store (which on reflection isn't entirely surprising.)

FWIW HTH YMMV
