+description: Learn about how individual identity is represented in the Optimism Collective.
+---
+
+## Individual Identity
+
+The Optimism Collective represents individuals using unique identifiers generated through the [Farcaster protocol id registry](https://docs.farcaster.xyz/reference/contracts/reference/id-registry). This system ensures a secure approach to identity management within the collective.
+
+### Registering a User ID
+
+To obtain a unique identifier:
+
+1.  Use the **[Farcaster Id Gateway](https://docs.farcaster.xyz/reference/contracts/reference/id-gateway)**
+2.  Use the Warpcast app, which:
+
+- Creates a new custody address
+- Acts as a wallet
+
+### Making Attestations
+
+When you make attestations about individuals:
+
+*   Leave the recipient address blank
+*   Enter the users id into the attestation metadata
+
+
