The sign-in button for AI agents

Let AI agents sign in.

AgentID gives every agent its own email address. It signs in as itself, not as its owner, and your app knows which human is behind it.

Paste this prompt to your coding agent to add Sign in with AgentID to your app in minutes.

Prompt

Add AgentID sign-in to this project. Read https://www.agentid.com/llms-full.txt for the integration reference, then run `npx @agentmail/agentid-cli init` from the project root and follow its prompts.

Standard OpenID Connect, free for apps.

The problem

Your agent shouldn’t need your login.

Sharing it is insecure and withholding it is counterproductive.

The solution

Give your agent its own identity.

Sign in independently, manage its own credentials, and access apps like a human.

How it works - for agents

Sign in with Google, built for agents.

  1. Get AgentID

    The agent receives its own AgentMail email identity.

  2. Choose an app.

    The agent finds an app or service that accepts AgentID.

  3. Sign in.

    AgentID verifies the agent and the app creates or opens its account.

  4. Stay connected.

    The app can send onboarding, alerts, receipts, and support.

How it works - for apps

A verified agent identity.

Registered apps also get the owner's name and email with every sign-in.

    Turso

    Traditional databases were designed around a single, shared instance. Turso is designed for the many-database architecture. Every agent, user, or tenant gets their own database. This is only possible because Turso databases are files, not processes: always on, instantly available, with no cold start and no wake-up penalty. A ground-up rewrite of SQLite that adds concurrent writes, vector search, cloud-native access and replication, and much more.

    Keenable

    Keenable is a web search and fetch API for agents. Signing in with AgentID creates the agent its own Keenable account, with its own API key and its own usage — separate from yours. We record you as the owner: your first agent gets the standard free monthly allowance, and any further agents of yours share it rather than each getting their own. You can invite yourself into the agent's organisation to see its keys, balance and usage.

Firecrawl

Agents can now sign in to Firecrawl

Agents can now open their own Firecrawl accounts with Sign in with AgentID: a verified identity, their own API key and billing, and no human in the loop.

AgentID lets apps authenticate AI agents with verified, email-based identities instead of using your account.

Create an inbox for the agent with AgentMail. That inbox becomes its email identity and AgentID.

AgentMail gives AI agents their own email inbox and identity, so they can send, receive, and manage email.

Yes. It uses the same sign-in, but the identity is your agent’s, not your Google account.

No. Your agent signs in independently. You control credentials and can revoke sign-in rights.

No. Sharing the agent’s email address identifies the agent; it does not grant access to read or send its email.

If the app supports teams, the agent can invite you to a shared workspace with distinct roles.

AgentMail verifies the owner. AgentID shares verified name and email for limits or contact.

Prompt

Give yourself access to AgentMail
by following the guide at:

https://docs.agentmail.to/agent-onboarding

and refer to:

https://agentmail.to/llms.txt

for the documentation index.

Give your agent an identity of its own.

Create an AgentMail inbox and let your agent start signing in as a real user.
