Please wait 5-10 minutes before attempting to login with your new password. This is because it takes up to 10 minutes before your new password has propagated to all machines on the cluster.
We strongly recommend using a password vault application or website like the UCSF-provided Keeper Password Vault to generate and store your passwords.
As long as your password has not yet expired, you can change your password either via our web interface, or from the Wynton HPC command line. Only passwords adhering to the Unified UCSF Enterprise Password Standard are accepted. Attempts to update to an insufficient password will produce an informative error message.
You can change your password before it expires using the ‘RBVI Kerberos Web Interface’ site;
To access the page, enter your current Wynton HPC
‘Username’ (e.g. alice) and ‘Password’ (must not be expired)
in the browser pop-up panel
Upon successful login, you will reach the ‘Resource for Biocomputing, Visualization, and Informatics’ page, which allows you to set a new password
Wait 10 minutes for your new password to propagate before using it

Changing password for user alice.

Wait 10 minutes for your new password to propagate before using it.
After waiting for 10 minutes for your new password to propagate, you can verify your Wynton username and password using either of the below alternatives. If neither works for you, you might have to reset your password. If so, see below for instructions.
To test your Wynton credentials, try to login to Wynton HPC via SSH. If you have SSH keys set up, you can force SSH to ignore those and only accept password entries by using:
{local}$ ssh -o PreferredAuthentications=password alice@log1.wynton.ucsf.edu
by replacing alice with your username.
Alternatively, you can verify your credentials from your browser:
Go to https://www.cgl.ucsf.edu/admin/kerbtest.py in your browser. A popup panel titled ‘Sign in https://www.cgl.ucsf.edu’ is opened by the browser.
Enter your Wynton login credentials in the two fields ‘Username’ (e.g. alice) and ‘Password’ and click ‘Sign in’.
If you entered correct credentials, you will get to a confirmation page saying so. If you entered incorrect credentials, there will be no error message and the popup will appear again.
If your Wynton password has expired, please email password@wynton.ucsf.edu to have it reset.
Account are personal and login credentials must not be shared with others. If detected, access to the account will be automatically disabled. It is still possible and easy for multiple users to share and collaborate on the same folders and scripts. Don’t hesitate to ask if you don’t know how to do this - we’re here to help.
