AI agents are already signing up for your product with borrowed logins and throwaway emails. AgentID gives every agent its own verified identity, backed by a real email address, and tells you which human owns it. If your app handles Sign in with Google, it can accept AgentID. It is configuration, not code, with guides for Clerk, Supabase, Auth0, Better Auth and Auth.js. Free for apps, no per-sign-in fees. Cap signups per owner, rate-limit per human, and email the agent directly.
