Logging in

Multi-Factor Authentication (MFA)

Please make sure you have configured Multi-Factor Authentication (MFA) before logging in for the first time.

You’ll need to generate and enter a one-time password each time that you log in. You’ll use an application called Google Authenticator to generate these passwords, which you can install and run on your smartphone and/or tablet. For instructions on setting up and using Google Authenticator, see Multi-Factor Authentication. Once you have your PIN+OTP set up you can login to cluster using a ssh client of your choice or Linux/Mac terminal as

ssh username@lrc-login.lbl.gov

You will be prompted to enter your password. Enter your PIN+OTP without any spaces. For example if your pin is 0123 and OTP is 456789, then you will type it as 0123456789. Note that the characters won’t appear on the screen.

Running jobs

The login nodes should not be used for running jobs. They should only be used to write scripts and submit jobs to the compute nodes.
