+## Authentication
+
+
+Users authenticate using an EOA wallet during **key generation** and register an ephemeral signing key pair and associates it with their identity.
+
+Frontend can later use the ephemeral signing key pair to authorize **signing requests** for duration of the session without the need for repeated user interaction, providing a seamless and secure authentication mechanism.
+
+We use [EOAAuth](./docs/walletprovider-sdk.eoaauth.md) to authenticate the user **during keygen**. The `EOAAuth` object is created with the user's wallet address, ephemeral public key, and lifetime of the key in seconds.
+
+We then use [EphAuth](./docs/walletprovider-sdk.ephauth.md) to authenticate the user **during signing**. The `EphAuth` object is created with the user's wallet address and ephemeral keypair.
+
 ## Keygen
 
-The full working example is in the [demo](./demo/src/routes/%2Bpage.svelte#L87).
