Managing your TACC Account

Last update: February 24, 2025

In order to access any TACC compute or storage resource you must maintain an "Active" TACC user account. You may view your account status at any time on the TACC Accounts Portal in the User Profile section. Table 1. below lists all possible conditions for your account.

Tip

If you are having login issues see TACC's Login Support Tool to resolve problems.

If your account status is "Active" and you still can't login, try un-pairing and re-pairing your MFA device.

Deactivated Accounts

If you have not accessed your account within the past 120 consecutive days, your account will be automatically deactivated in accordance with UT's security protocols. To re-activate your acccount, login to the TACC Accounts Portal and request an activation link.

Important

Once you have re-activated your account, you will need to un-pair and re-pair your two-factor authentication.

New Accounts

Any user of TACC resources must first obtain a TACC account. A TACC account email is of the form username@tacc.utexas.edu. All new users are required to authenticate with a UT approved Identity Provider.

To create a new account:

  1. Go to the TACC Accounts Portal and click "Create a New Account" to begin registration.
  2. Check for an email containing a confirmation and activation link. Once you confirm your email, your account status will update to either "Pending" or "Active".
  3. If your account status is "Pending" then your account request will need further review by our User Services team. No action is required and a team member will reach to you.
  4. Once your account is "Active":

Warning

An individual may not have more than one TACC account. Shared accounts and/or multi-user accounts are strictly prohibited.

Tip

In order to log on to TACC's HPC resources, your TACC account must be Active AND you must have an active allocation on that particular resource.

Identity Management

As part of ongoing cybersecurity enhancements, TACC now requires using a 3rd party Identity Provider. Any user registering for a new account, reactivating a deactivated account, or updating their profile will be required to authenticate using one of the UT approved Identity Provider services listed below. All existing accounts will be required to authenticate with one of these identity providers at the annual account profile update.

  • UT EID
  • Apple
  • Google
  • Microsoft

Important

Use your institution's email, not your Apple, Google or Microsoft email, when registering/activating your TACC account.

Login Problems: Improper ssh Configuration!

If you see this message:

--> Verifying valid ssh keys...

Improper ssh configuration!
Please reconfigure or contact TACC consulting for assistance.

This is most likely because you have modified your ./ssh/known_hosts file. The solution is to generate a new .ssh folder to clear any conflicting keys/logins.

  1. Go to your home directory:

    $ cd $HOME

  2. Rename your .ssh folder to old_ssh to save the contents should you need to revisit them at any point: 

    $ mv .ssh old_ssh

  3. Log out of the system and then log back in. This will auto-generate a new .ssh folder and key for you.

Table 1. TACC Account Status

Account Status Description
Active All is well. Active account holders may log on to the TACC User Portal as well as any allocated TACC resources.
Pending Email Confirmation You haven't confirmed your email account. If you haven't received the confirmation email, check your spam or junk folder and any filters. Add "no-reply@tacc.utexas.edu" to your safe senders list, then request the activation link again.
Pending Your account is under administrative review.
Deactivated Reactivate your account by logging into the TACC Accounts Portal and requesting an activation link. You will have to re-pair MFA once your account is reactivated.
Suspended If your account is suspended you will be prohibited from logging into the TACC User Portal and as well as any TACC HPC resources. Please submit a help desk ticket and a member of our User Services team will respond. Account suspension may result if:
  • your HPC jobs are violating Good Conduct Policies or causing harm to our systems
  • your account usage is in violation of TACC's Acceptable Use Policy.
