How to Re-set Your HPC Cluster Password

Note that account passwords for the main HPC system (raad2) and the GPU cluster (raad2-gfx) are synced in one direction every few minutes. More precisely, the password established on a user's raad2 account is automatically propagated to her GPU cluster account every 5 minutes. Consequently, the account password must always be changed on the main system (the nodes raad2a or raad2b), and NOT on the GPU system (the node raad2-gfx).

Your Old Password Expired

If your raad2 account password expires, or you wish to reset it of your own accord you must use the passwd command while logged in on raad2. The passwd command will ask you first for your current password, and then prompt you to type a new password twice for confirmation. If passwd does not like your proposed new password for lack of sufficient complexity, it will tell you so in its output and quit without making the change. You may therefore have to repeat the use of passwd several times until you satisfy it with a complex (and therefore strong) enough password.

You Forgot Your Password

If you've forgotten your HPC Cluster account password, please open a service desk ticket by sending email to mentioning this fact and request assistance in resetting the password. Your query will be directed to RC staff and we will then schedule either an in-person visit or a remote video call with you where we must compare your likeness to your picture on any government (or TAMUQ) issued ID. Once your identity is confirmed, we will proceed with the reset.

Password Complexity Rules

Whenever you create a new HPC Cluster account password, the following complexity rules must be respected. The password should:

  • be at least 10 characters in length
  • contain at least 3 out of these 4 character classes: (1) lower case alphabetic characters (2) upper case alphabetic characters (3) numeric digits (4) special characters
  • NOT contain words found in a dictionary
  • NOT contain 3 or more consecutive numeric digits, such as "193", "10375", "937", etc.
  • NOT contain sequences of 3 or more "adjacent" alphabetic characters such as "abc", "lmnop", "asdf", etc.

How to Re-set Your VPN Password

Your VPN password expires 365 days after the last time it was changed. If you are trying to use your VPN username and password to establish a VPN connection to TAMUQ, and the VPN client repeatedly solicits the password without accepting the one you type, it may be an indication that your previous password has expired. Or perhaps you may simply have forgotten your VPN password. In either case, to reset your password please follow these instructions:

  • Go to and click "Forgot Password" at the bottom of the page.
  • Enter the VPN account username (e.g. john.doe) or your email address (e.g. and press "Continue".
  • You will see a confirmation message indicating the e-mail is sent to your registered institutional address. It is the email address you submitted when requesting your HPC Cluster account.
  • Check your institutional email inbox for a message with a password reset link. Be sure to check your spam folder if it does not arrive within a few minutes.
  • Click the link in the email and enter a new password; note the complexity requirements. Press "Submit".
  • At the login prompt, enter your TAMUQ username and press "Continue"
  • Enter the new password you just set in order to log in.
  • Accept the Terms and Conditions.

If you have not previously been enrolled with our two factor authentication service "Duo", you may also have to complete a few more steps:

  • You will be prompted to begin the setup of Duo two-factor authentication. Press "Begin Setup". Follow the on-screen instructions to enroll your smartphone into the Duo system.
  • Download the "Duo Mobile" app from your device's app store. After the download is complete, select "I have Duo Mobile". This will generate a QR code on the computer screen.
  • Open the "Duo Mobile" app on your phone and scan the QR code generated. You can see "Texas A&M University at Qatar" listed as a DUO-PROTECTED account on your mobile app.

Once this registration is successful, every attempt to connect to TAMUQ VPN will generate a notification to your registered smartphone via the Duo app you have installed. Be sure to watch for such notifications during VPN logins and confirm your login attempts by responding to these Duo notifications.
