Authenticating yourself
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.

If you're already logged in to the ECMWF website, or have recently logged in to this service, the password prompt might be skipped. |

If your computer does not have a browser or cannot display one, you may use the Teleport SSH access - Browserless Login Python Module for the authentication. |
If the process is successful, you will see an output such as:

Setup your SSH config
We strongly recommend setting up all the SSH options needed for the connection instead of passing them on the command line.
...
Edit the file ~/.ssh/config on your computer and add the snippet below. You may create it if it does not exist. You should replace ecmwfusername by your registered ECMWF user and user.address@somewhere.com by your registered email address at ECMWF.
