 Pocket ID is a simple OIDC provider that allows users to authenticate with their passkeys to your services.

-<img src="https://github.com/user-attachments/assets/953c534c-b667-44e5-b976-a59142f1efb8" width="1200"/>
+→ Try out the [Demo](https://pocket-id.eliasschneider.com)

-The goal of Pocket ID is to be a simple and easy-to-use. There are other self-hosted OIDC providers like [Keycloak](https://www.keycloak.org/) or [ORY Hydra](https://www.ory.sh/hydra/) but they are often too complex for simple use cases. Additionally, Pocket ID only support passkey authentication which is a passwordless authentication method.

+
+Additionally, what makes Pocket ID special is that it only supports [passkey](https://www.passkeys.io/) authentication, which means you don’t need a password. Some people might not like this idea at first, but I believe passkeys are the future, and once you try them, you’ll love them. For example, you can now use a physical Yubikey to sign in to all your self-hosted services easily and securely.

+### Before you start
+
+Pocket ID requires a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts), meaning it must be served over HTTPS. This is necessary because Pocket ID uses the [WebAuthn API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API).

 - [Node.js](https://nodejs.org/en/download/) >= 20
- [Go](https://golang.org/doc/install) >= 1.22
+- [Go](https://golang.org/doc/install) >= 1.23

 - [Caddy](https://caddyserver.com/docs/install) (optional)

 1. Copy the `.env.example` file in the `frontend` and `backend` folder to `.env` and change it so that it fits your needs.

-### Add Pocket ID as an OIDC provider
+### Nginx Reverse Proxy

-You can add a new OIDC client on `https://<your-domain>/settings/admin/oidc-clients`
+To use Nginx as a reverse proxy for Pocket ID, update the configuration to increase the header buffer size. This adjustment is necessary because SvelteKit generates larger headers, which may exceed the default buffer limits.

-After you have added the client, you can obtain the client ID and client secret.
+```nginx
+proxy_busy_buffers_size   512k;
+proxy_buffers   4 512k;
+proxy_buffer_size   256k;
+```

-You may need the following information:
+## Proxy Services with Pocket ID

- **Authorization URL**: `https://<your-domain>/authorize`
- **Token URL**: `https://<your-domain>/api/oidc/token`
- **Certificate URL**: `https://<your-domain>/.well-known/jwks.json`
- **OIDC Discovery URL**: `https://<your-domain>/.well-known/openid-configuration`
- **PKCE**: `false` as this is not supported yet.
+As the goal of Pocket ID is to stay simple, it doesn't have a built-in proxy provider. However, you can use [OAuth2 Proxy](https://oauth2-proxy.github.io/oauth2-proxy) to add authentication to your services that don't support OIDC.

+## Account recovery
+
+There are two ways to create a one-time access link for a user:
+
+1. **UI**: An admin can create a one-time access link for the user in the admin panel under the "Users" tab by clicking on the three dots next to the user's name and selecting "One-time link".
+2. **Terminal**: You can create a one-time access link for a user by running the `scripts/create-one-time-access-token.sh` script. To execute this script with Docker you have to run the following command:
+   ```bash
+   docker compose exec pocket-id sh "sh scripts/create-one-time-access-token.sh <username or email>"
+   ```
