--- title: "Sign in" description: "arkor login, logout, whoami." --- You can use Arkor anonymously without ever signing in: `arkor dev` bootstraps an anonymous identity for you on first launch. To tie work to your Arkor Cloud account instead, use `arkor login`. ## Sign in ```bash pnpm arkor login ``` ```bash npm arkor login ``` ```bash yarn arkor login ``` ```bash yarn run arkor login ``` ```bash bun arkor login ``` The CLI prompts you to pick **OAuth (browser)** or **Anonymous**. Pick OAuth to sign in to your Arkor Cloud account; the CLI opens a browser, you authorize, and credentials land in `~/.arkor/credentials.json`. To skip the picker: ```bash pnpm arkor login --oauth ``` ```bash npm arkor login --oauth ``` ```bash yarn arkor login --oauth ``` ```bash yarn run arkor login --oauth ``` ```bash bun arkor login --oauth ``` In CI, use `--anonymous` instead; OAuth needs a browser. ## Check who you are ```bash pnpm arkor whoami ``` ```bash npm arkor whoami ``` ```bash yarn arkor whoami ``` ```bash yarn run arkor whoami ``` ```bash bun arkor whoami ``` Prints the current identity and the orgs you can reach. ## Sign out `arkor logout` asks before deleting `~/.arkor/credentials.json`, and the confirmation defaults to **No**. For anonymous credentials, deleting the file permanently loses access to that anonymous identity unless you backed it up yourself; the next `arkor dev` will bootstrap a fresh anonymous identity. OAuth users can run `arkor login --oauth` again. ## Reference For the full picker / flag matrix, the anonymous-vs-OAuth tradeoffs, token expiry behavior, and every error message, see the [auth reference](/docs/framework/cli/auth).
