No password. You get a link: it opens the app on this device and is valid for 15 minutes. If there's no account yet at this address, the same link creates one.
Log in at the dock, before you set off. Once the device is set up, the app works without coverage: downloaded maps, calculated route and the structures along the way stay on board.
By continuing, you accept the terms of use and the privacy policy. Your location is never shared; lock-wait observations are only contributed with your consent, and anonymised.
