Lens Authentication is one of 6 APIs that [Lens Protocol](https://apis.io/providers/lens-protocol/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authentication, SIWE, Wallets, and Bearer Token. The published artifact set on APIs.io includes API documentation.

Lens authentication uses a sign-in-with-Ethereum style challenge: a client requests a signing message from the Lens API, the user signs it with their wallet, and the API returns short-lived access and refresh tokens scoped to a specific Account and App. The auth flow supports owner, manager, and onboarding-user roles.
