Signing an agent in

Each agent program needs an account to talk to its AI model, for example a Claude account for Claude Code or a ChatGPT account for Codex. Each agent keeps its own sign-in, so signing in to the program on your own computer does not sign in an agent.

Ways to sign in

Open the agent's Settings and find the account section for its agent program.

• Sign in with… There is a button for each way the program itself offers, for example "Sign in with ChatGPT" for Codex. The agent has to be running for these buttons to appear. A browser window may open; the button waits until you have finished there.
• Use a key. Paste a key instead. It is kept encrypted and saved as a named account, and the agent uses it from its next start.
• The Terminal tab. A program that shows no button is signed in from the agent's Terminal tab. Signing in there affects that agent only.

One sign-in for many agents

Once an account has been saved, every other agent on the same program shows it under Saved accounts, with a Use this button. One sign-in can serve as many agents as you choose. A new agent is signed in with the most recently saved account, and the New menu lets you pick another, or none.

Sharing an account shares nothing else. Two agents on the same account still have separate settings, connectors, skills and files. Forget removes a saved account from every agent that used it.

Using a Claude subscription with Claude Code

Run this once in a terminal on your computer:

claude setup-token

Paste what it prints into the key field. Every agent you choose can then use your Claude subscription. A pay-as-you-go key from the Anthropic Console works in the same field.

If an agent says it is not signed in

If you send a message to an agent whose program is not signed in yet, a red banner says so, for example "Codex is not signed in for this agent. Sign it in under Settings, then try again." Sign the agent in, then send your message again.
