How to Fix: Authentication failed for Azure Git

The 'Authentication failed' error when cloning a web app in Azure can be frustrating for developers who are trying to deploy or manage their applications. This issue affects users who have set up their Azure Git repository and are attempting to clone it using the command line.

This problem is especially vexing because it involves a password change that has already been made in the Azure portal, which should ensure that authentication credentials are updated correctly.

🛑 Root Causes of the Error

• The primary reason for this error is that Azure SCM (Source Control Management) repositories have a different authentication mechanism than Azure App Service repositories. When you update your deployment credentials in the Azure portal, it only updates the credentials for your App Service repository, not for your SCM repository. As a result, when you try to clone your SCM repository using the command line, Git is unable to authenticate with the correct credentials.
• Another possible cause is that the password change has not propagated correctly to the SCM repository. This could be due to various reasons such as network connectivity issues or delays in updating the credentials.

🚀 How to Resolve This Issue

✨ Wrapping Up

To resolve the 'Authentication failed' error when cloning a web app in Azure, try updating your Azure App Service Repository Credentials using the Azure portal. Alternatively, consider using Azure CLI or Azure DevOps to manage your Git repositories. If you continue to experience issues, ensure that your network connectivity and credentials are correct.
