Sign in with your email and password or an enabled Google or GitHub account. You can then use the resources and settings your organization role allows. Nodus does not require QR scanning, an authenticator app or a separate verification code after sign-in. Email verification for new accounts and password recovery still apply.

CLI and device login use your existing signed-in session. API keys and service account tokens keep their own scopes. Review them under [API keys](https://www.nodus-compute.ai/docs/guides/access/api-keys-and-scopes/).
