Azure Repos is part of Azure DevOps. The first time you authenticate, the helper opens a browser window to Microsoft login. Subsequent authentication is non interactive. ## Installation **Download** binary from https://github.com/hickford/git-credential-azure/releases. Then test that Git can find the application: git credential-azure If you have problems, make sure that the binary is [located in the path](https://superuser.com/a/284351/62691) and [is executable](https://askubuntu.com/a/229592/18504). ### Linux [Several Linux distributions](https://repology.org/project/git-credential-azure/versions) include a git-credential-azure package: [![Packaging status](https://repology.org/badge/vertical-allrepos/git-credential-azure.svg?exclude_unsupported=1&header=)](https://repology.org/project/git-credential-azure/versions) ### Go users Go users can install the latest release to `~/go/bin` with: go install github.com/hickford/git-credential-azure@latest ## Configuration This assumes you already have a storage helper configured such as cache or wincred. ```sh git config --global --add credential.helper azure ``` ### Subtleties with multiple users or organizations If you use more than one user or organization across Azure Repos, make sure that the remote URLs include usernames. This is the default if you copied the URLs from the Azure Repos web interface. Alternatively, you can set [credential.useHttpPath](https://git-scm.com/docs/gitcredentials#Documentation/gitcredentials.txt-useHttpPath) to store separate credentials for each repo: ```sh git config --global credential.https://dev.azure.com.useHttpPath true ``` ### Unconfiguration Run: git config --global --unset-all credential.helper azure ## Development Install locally with `go install .`. ### Debugging Use the `-verbose` flag to print more details: ```sh git config --global --unset-all credential.helper azure git config --global --add credential.helper "azure -verbose" ``` ## See also *
