Example usage

Authorization Code Flow

Use this flow when your application needs to authenticate a real user.

It will:

1. Open the user’s browser
2. Redirect them to your identity provider’s login page
3. Wait for the user to authenticate
4. Receive an authorization code
5. Exchange it for an access token

Best for CLIs, desktop apps, and tools acting on behalf of a user.

from oidc_auth_client import Config, AuthorizationCode, OidcProvider

config = Config(
    client_id="<your-client-id>",
    oidc_provider=OidcProvider(
        openid_configuration_url="<auth-provider-url>/.well-known/openid-configuration"
    )
)

# Sign in with the identity provider in the opened browser!
access_token = AuthorizationCode(config=config).get_token()

Client Credentials Flow

Use this flow when your application needs to authenticate as itself, without user interaction. The client exchanges its own client_id and client_secret directly for an access token.

Ideal for:

• Backend services
• Server-to-server APIs
• Cron jobs
• Automated tasks

from oidc_auth_client import ClientCredentials, OidcProvider, TokenCache
from oidc_auth_client.client_credentials import ClientCredentialsConfig

config = ClientCredentialsConfig(
    client_id=CLIENT_ID,
    client_secret=CLIENT_SECRET,
    oidc_provider=OidcProvider(openid_configuration_url=OPENID_CONFIGURATION_URL),
)

access_token = ClientCredentials(config=config).get_token()

Token caching between runs

To allow the user to cache the token between usages, configure with a TokenCache. Will store the token in plaintext on the users system.

from oidc_auth_client import Config, TokenCache

config = Config(
    # ...
    token_cache=TokenCache(),
)
