# oidc-keychain

`oidc-keychain` enables re-using [`oidc-agent`](https://indigo-dc.gitbook.io/oidc-agent/user/oidc-agent) between login sessions. Since version `4.3.0` [oidc-agent-service](https://indigo-dc.gitbook.io/oidc-agent/user/oidc-agent-service) is used to utilize a running agent across sessions. Still accounts are loaded when needed (using [`oidc-add`](https://indigo-dc.gitbook.io/oidc-agent/user/oidc-add)), and the `OIDCD_PID` and `OIDC_SOCK` environment variables are set. `oidc-keychain` is commonly used inside `.bash_profile` or similar to start `oidc-agent` when needed.

For example this line in `.bash_profile`

```
eval `oidc-keychain --accounts <shortname>`
```

starts `oidc-agent` when needed, loads the account if it isn't already loaded, and sets the oidc environment variables so other applications can locate the agent.
