Once every 12 hours, you will need to refresh your tokens with the tsh command. SSH connections may remain active for longer than 12 hours, but new connections will require re-authentication. To authenticate yourself, run tsh , giving the location of our Teleport gateway: Your default web browser will open. You should login with your email address, ECMWF password, and then the code from your Time-based One-Time-Password (TOTP) device or the 8-digit one-time passcode from your ActivIdentity (HID) security token if you have not configured your TOTP yet.
