The uv auth CLI

uv provides a high-level interface for storing and retrieving credentials from services.

Logging in to a service

To add credentials for service, use the uv auth login command:

$ uv auth login example.com

This will prompt for the credentials.

The credentials can also be provided using the --username and --password options, or the --token option for services which use a __token__ or arbitrary username.

Note

We recommend providing the secret via stdin. Use - to indicate the value should be read from stdin, e.g., for --password:

$ echo 'my-password' | uv auth login example.com --password -

The same pattern can be used with --token.

Once credentials are added, uv will use them for packaging operations that require fetching content from the given service. At this time, only HTTPS Basic authentication is supported. The credentials will not yet be used for Git requests.

Note

The credentials will not be validated, i.e., incorrect credentials will not fail.

Logging out of a service

To remove credentials, use the uv auth logout command:

$ uv auth logout example.com

Note

The credentials will not be invalidated with the remote server, i.e., they will only be removed from local storage not rendered unusable.

Showing credentials for a service

To show the credential stored for a given URL, use the uv auth token command:

$ uv auth token example.com

If a username was used to log in, it will need to be provided as well, e.g.:

$ uv auth token --username foo example.com

Configuring the storage backend

Credentials are persisted to the uv credentials store.

By default, credentials are written to a plaintext file. An encrypted system-native storage backend can be enabled with UV_PREVIEW_FEATURES=native-auth.
