# tb login

Authenticates with your Tinybird account.

By default, the command opens a browser window for authentication. You can also use the `--method code` option to authenticate using a temporary code instead of a browser.

The credentials are stored in the `.tinyb` file. See [.tinyb file](/forward/dev-reference/datafiles/tinyb-file).
