oidc-agent

oidc-agent is a set of tools to manage OpenID Connect tokens and make them easily usable from the command line. We followed the ssh-agent design, so users can handle OIDC tokens in a similar way as they do with ssh keys.

oidc-agent is usually started in the beginning of an X-session or a login session. Through use of environment variables the agent can be located and used to handle OIDC tokens.

The agent initially does not have any account configurations loaded. You can load an account configuration by using oidc-add. Multiple account configurations may be loaded in oidc-agent concurrently. oidc-add is also used to remove a loaded configuration from oidc-agent. oidc-gen is used to initially generate an account configurations file (Help for different providers).

Full documentation can be found at https://indigo-dc.gitbooks.io/oidc-agent/.

We have a low-traffic mailing list with updates such as critical security incidents and new releases: Subscribe oidc-agent-user

Refer to the documentation

Debian:

make deb

Quickstart

After installation the agent has to be started. Usually the agent is started on system startup and is then available on all terminals ( see integration). Therefore, after installation the options are to restart your X-Session or to start the agent manually.

eval `oidc-agent-service start`

This starts the agent and sets the required environment variables.

Create an agent account configuration with oidc-gen

For most OpenID Connect providers an agent account configuration can be created with one of the following calls. Make sure that you can run a web-browser on the same host where you run the oidc-gen command.

oidc-gen <shortname>
oidc-gen --pub <shortname>

For more information on the different providers refer to integrate with different providers.

oidc-gen supports different OIDC flows. To use the device flow instead of the authorization code flow include the --flow=device option.

After an account configuration is created it can be used with the shortname to obtain access tokens. One does not need to run oidc-gen again unless to update or create a new account configuration.

Use oidc-add to load an account configuration

oidc-add <shortname>

However, usually it is not necessary to load an account configuration with oidc-add. One can directly request an access token for a configuration and oidc-agent will automatically load it if it is not already loaded.

Obtaining an access token

oidc-token <shortname>

Alternatively, it is also possible to request an access token without specifying the shortname of a configuration but with the issuer url:

oidc-token <issuer_url>

This way is recommended when writing scripts that utilize oidc-agent to obtain access tokens. This allows that the script can be easily used by others without them having to update the shortname.

List existing configuration

oidc-add -l
oidc-gen -l

These commands both give a list of all existing account configurations.

A list of the currently loaded accounts can be retrieved with:

oidc-add -a

Updating an existing account configuration

An existing account configuration can be updated with oidc-gen:

oidc-gen -m <shortname>

Reauthenticating

If the refresh token stored in the account configuration expired a new one must be created. However, it is not required to create a new account configuration, it is enough to run:

oidc-gen <shortname> --reauthenticate
