CAVEATS

Requires valid OAuth2 client credentials (client ID and secret). The authorization code flow opens a browser and starts a local server for the redirect URI. Tokens are printed to stdout and should be handled securely. Some grant types require the redirect URI to be pre-registered with the authorization server.

HISTORY

oauth2c was created by Cloudentity to simplify OAuth2 token acquisition from the command line, supporting the full range of OAuth2 grant types.
