Add an account
Open the More menu in the title bar and choose Add account….
Pick a provider
Pick Codex, Claude or Grok, name the account and add it.
Sign in
Use the provider's own login. Each one works a little differently:
- Codex
Choose Connect Codex, then Sign in or Use a device code.
Pick a model and effort, then press Start terminal. Astra needs High effort or above.
- Claude
Choose Sign in to Claude. Every terminal on the account shares this login.
Finish Claude Code's first-run setup once before usage can show.
- Grok
Sign in through the official Grok Build client.
Sign-in saved means the client holds local credentials and renews them itself.
You can connect four or more accounts.
Your existing logins stay put
Miko never imports the logins already on your Mac. Every account signs in on its own.
