AgentID

What is AgentID?

AgentID is a sign-in system for AI agents from the team behind AgentMail. Each agent gets its own verified email address and signs in to apps on its own, without borrowing your account. Apps add it as a standard OpenID Connect provider, like Sign in with Google, free of charge.

Top Features:

• Agent email identity: every agent signs in with its own verified address, not yours.
• One-time signatures: apps never receive a password or any key they could reuse.
• CLI setup: one command configures Clerk, Auth0, Supabase, Better Auth, or Auth.js apps.

Use Cases:

• Agent signups: let agents create accounts and log in without your credentials.
• App onboarding: accept agent users in your SaaS through a standard OIDC connection.
• Owner checks: see the verified human behind each agent and cap their accounts.

Who Can Use AgentID?

• SaaS developers: teams that want agents to sign up for their app safely.
• Agent builders: developers whose agents need to log in to many apps.
• Security teams: people who want revocable per-agent credentials instead of shared logins.

Pricing

• App integration (free): adding agent sign-in to your app is free for every provider.
• AgentMail Free ($0): three agent inboxes and 3,000 emails each month for testing.
• AgentMail Developer ($20 per month): ten inboxes and 10,000 emails monthly for small agent projects.

Pros and Cons

Pros:

• Standard protocol: built on OpenID Connect, so most auth stacks support it quickly.
• No shared passwords: agents never carry your login, limiting damage from a leaked key.
• Instant revocation: revoking an agent stops it from signing in anywhere at once.

Cons:

• Early ecosystem: few apps show the sign-in button yet, so coverage is limited.
• Tied to AgentMail: agents need an AgentMail inbox, adding another service to manage.
• Developer focused: setup assumes familiarity with auth providers, tokens, and callback URLs.

FAQs:

1) Is it like signing in with Google?

Yes, it uses the same OpenID Connect standard, with an agent signing in.

2) Does the app get a password?

No, each sign-in uses a one-time signature that cannot be reused.

3) Is it free for app developers?

Yes, integration is free, since revenue comes from AgentMail inbox plans.

4) Which auth providers are supported?

Clerk, Auth0, Supabase, Better Auth, Auth.js, and custom OIDC setups all work.

5) What happens if I revoke my agent?

The agent stops signing in immediately, and no other agent is affected.
