-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.
 
 ## Setup
 
 > [!WARNING]  
 > Pocket ID is in its early stages and may contain bugs.
 
+### 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) which requires a secure context.
