Learn more about authentication in Azure DevOps.
The following authentication options are available in Azure DevOps.
Personal Access Tokens
To use access tokens, you need to create a personal access token in your Azure DevOps account, where you have to set some Code access scope in your repositories and use it when configuring a VCS root.
Required Access Scope
Alternate Authentication Credentials
To use the login/password pair authentication, you have to enable alternate credentials in your Azure DevOps account, where you can set a secondary username and password to use when configuring a VCS root.
NTLM/Kerberos on Linux and macOS
To use this authentication method, check that your machine includes Kerberos libraries and that the authentication is properly configured. If you encounter any issues, please check the steps described in the Microsoft documentation.
