Introduction
If you work with multiple GitHub accounts—whether for personal projects, client work, or different organizations—you may encounter situations where Git continues authenticating with the wrong account. This often results in authentication errors even though you have the necessary permissions to access the repository.
I recently faced this issue while cloning a private repository from another GitHub organization. Despite having the correct access and verifying my Git configuration, every clone attempt failed because Windows was automatically reusing previously cached GitHub credentials.
After investigating the problem, I found that the issue wasn't related to Git itself. Instead, it was caused by cached credentials stored in Windows Credential Manager.
In this article, you'll learn why this happens, how Git authentication works on Windows, and the exact steps to resolve the issue.
The Problem
While attempting to clone a private GitHub repository, I used the following command:
git clone https://github.com/algointellia2026/demo-repo.git
Instead of prompting me to authenticate, Git automatically used credentials that were already stored on my Windows machine.
As a result, I encountered one of the following errors:
Repository not found
remote: Repository not found.
fatal: Authentication failed
Permission denied
Even after confirming that my Git configuration was correct:
git config --global user.name
git config --global user.email
the repository still could not be cloned.
At first, this appeared to be a Git configuration issue, but the actual cause was cached authentication credentials.
Why Git Configuration Isn't the Problem
A common misconception is that the following Git configuration determines which GitHub account is used during authentication:
git config --global user.name "Your Name"
git config --global user.email "[email protected]"
These settings only define the identity associated with your commits, including:
Commit author name
Commit author email
They do not control authentication when cloning, pushing, or pulling repositories.
Repository authentication is handled separately through authentication mechanisms such as:
Windows Credential Manager
Git Credential Manager (GCM)
GitHub CLI (gh)
Personal Access Tokens (PATs)
SSH keys
Why This Happens
On Windows, Git commonly relies on Windows Credential Manager or Git Credential Manager (GCM) to securely store authentication credentials.
When Git connects to GitHub, it first checks whether valid credentials already exist in the credential store. If cached credentials are found, Git automatically reuses them without prompting you to sign in again.
While this behavior improves convenience, it can create problems when:
Working with multiple GitHub accounts
Switching between personal and organizational repositories
Accessing repositories owned by different organizations
Previously cached credentials no longer have the required permissions
Since Git silently uses the stored credentials, authentication fails before you're given the opportunity to sign in with the correct account.
Solution: Remove Cached GitHub Credentials
The fix is surprisingly simple.
Delete the old GitHub credentials stored in Windows so Git is forced to authenticate again.
Step 1: Open Windows Credential Manager
Press:
Win + R
Type:
control.exe /name Microsoft.CredentialManager
Then press Enter.
Step 2: Open Windows Credentials
Select:
Windows Credentials
Look for GitHub-related entries such as:
github.com
or
git:https://github.com
Delete every GitHub credential that is no longer needed.
Note: Removing these credentials only clears cached authentication. It does not delete any repositories or change your Git configuration.
Step 3: Clone the Repository Again
Run the clone command again:
git clone https://github.com/algointellia2026/demo-repo.git
Since Git no longer has cached credentials, it will prompt you to authenticate again.
Depending on your Git installation, one of the following may occur:
Your browser opens for GitHub sign-in.
Git Credential Manager prompts for authentication.
GitHub CLI requests login.
Git prompts for a Personal Access Token (PAT).
This time, sign in using the GitHub account that has access to the repository.
The repository should now clone successfully.
Verify Which GitHub Account Is Authenticated
If you're using the GitHub CLI, verify the currently authenticated account:
gh auth status
If necessary, authenticate again:
gh auth login
This ensures you're using the correct GitHub account before cloning, pushing, or pulling changes.
Git Identity vs. GitHub Authentication
Many developers confuse Git configuration with GitHub authentication.
| Git Configuration | GitHub Authentication |
|---|
| git config --global user.name | Windows Credential Manager |
| git config --global user.email | Git Credential Manager (GCM) |
| Defines commit author information | GitHub CLI (gh) |
| Used in commit history | Personal Access Tokens (PATs) |
| Local Git setting | SSH keys |
| Does not control repository access | Determines repository authentication |
Other Authentication Methods
Depending on your workflow, GitHub authentication may be handled using:
Windows Credential Manager
Git Credential Manager (GCM)
GitHub CLI (gh)
Personal Access Tokens (PATs)
SSH keys
If you frequently switch between GitHub accounts, using SSH keys or separate GitHub CLI profiles provides a smoother experience than relying solely on cached HTTPS credentials.
Common Git Commands
Check Git Configuration
git config --global user.name
git config --global user.email
Clone a Repository
git clone https://github.com/algointellia2026/demo-repo.git
Check GitHub Authentication
gh auth status
Sign In to GitHub
gh auth login
Troubleshooting Checklist
If you're still unable to clone a repository, verify the following:
You have permission to access the repository.
The repository URL is correct.
Old GitHub credentials have been removed from Windows Credential Manager.
You're authenticated with the correct GitHub account.
Your GitHub organization membership is active.
Two-factor authentication (2FA) requirements have been satisfied, if enabled.
You're using a valid Personal Access Token (PAT), if prompted.
Best Practices
To avoid similar authentication issues in the future:
Use GitHub CLI to manage multiple GitHub accounts.
Prefer SSH authentication when working with multiple organizations.
Remove outdated credentials from Windows Credential Manager periodically.
Verify your authenticated account before cloning private repositories.
Keep Git Credential Manager and GitHub CLI up to date.
Conclusion
If Git continues authenticating with the wrong GitHub account, the problem is usually not related to your Git configuration. In most cases, the issue is caused by cached credentials stored in Windows Credential Manager or managed by Git Credential Manager.
Removing outdated credentials forces Git to request authentication again, allowing you to sign in with the correct account and successfully access private repositories.
Understanding the distinction between Git identity (commit author information) and GitHub authentication (repository access) can save significant troubleshooting time, especially if you regularly work across multiple GitHub accounts or organizations.
For developers managing multiple GitHub identities, using SSH keys, GitHub CLI, or separate authentication profiles is often a more reliable long-term approach than relying solely on cached HTTPS credentials.
