1Password CLI get-started (summary)

Works on macOS, Windows, and Linux.
- macOS/Linux shells: bash, zsh, sh, fish.
- Windows shell: PowerShell.
Requires a 1Password subscription and the desktop app to use app integration.
macOS requirement: Big Sur 11.0.0 or later.
Linux app integration requires PolKit + an auth agent.
Install the CLI per the official doc for your OS.
Enable desktop app integration in the 1Password app:
- Open and unlock the app, then select your account/collection.
- macOS: Settings > Developer > Integrate with 1Password CLI (Touch ID optional).
- Windows: turn on Windows Hello, then Settings > Developer > Integrate.
- Linux: Settings > Security > Unlock using system authentication, then Settings > Developer > Integrate.
After integration, run any command to sign in (example in docs: op vault list).
If multiple accounts: use op signin to pick one, or --account / OP_ACCOUNT.
For non-integration auth, use op account add.
