whoami - Authentication Status

Overview

The whoami command displays your current authentication identity and the method used. Authentication is checked in priority order: license key first, then OAuth token. When neither is active, you are prompted to run nmbl login.

Run 'nmbl login' to authenticate with OAuth or provide a license key.

Exit Codes

0 - The user is authenticated via license key or OAuth.

Authentication methods

License key

If a LicenseKey is configured (e.g., in config.json or via CLI argument), it is validated first. A masked version of the key is shown — the first 4 and last 4 characters are preserved; everything in between is replaced with asterisks.

OAuth (Google)

If no valid license key is found, the stored OAuth token is checked. The command shows your email address and the UTC expiry time of the token.

login - Authenticate with OAuth
logout - Clear authentication tokens
