Claude Code Setup

Atom includes Claude Code, so no separate installation is required. Anthropic usage is billed through the Claude account or organization you authorize.

Sign in

1. Choose Claude Code in the model selector.
2. Click Sign In when Atom asks you to connect Claude Code.
3. Complete Anthropic’s browser authorization and return to Atom.

Switch accounts

Open Settings → Account → AI accounts, then click Change Account beside Claude Code. Team and Enterprise users can select their organization plan during Anthropic’s authorization flow.

For the complete work-account steps, see Switch Claude Code from a personal account to a work or Enterprise account.

Troubleshooting

• Wrong Claude account: Use Change Account in Atom Settings and choose the correct plan during authorization.
• Work organization missing: Confirm your administrator assigned you a Claude Code-enabled seat.
• Authentication error: Retry the sign-in from Settings → Account.
