Authentication

Arctos relies on an open standard for authenticating users registered to use Arctos. Any one who wants to interact with Arctos, from downloading data to managing data, must have a user account to authenticate their access.

OAuth

OAuth (Open Authorization) is an open standard for authorization that allows third-party applications to access user data on another service without needing the user’s password. Arctos uses OAuth to allow logging in via various providers. All Operators (those who can change things in the database) must authenticate via TACC/TAPIS.

TACC Account

If an operator does not have a TACC account, create your TACC account here.. If you have a .edu email address, it is strongly recommended to use it in your TACC profile, as these addresses are authorized without additional review. If you have another work email domain (e.g., .org, etc) please use that. All other email address types are subject to additional validation by TACC.

MFA

TACC and Arctos generally require MFA for accounts. TACC accounts created after February 07, 2023 should work without issue. For those created before this date with SMS MFA, you will have to un-pair and re-pair your mobile number.

• Log into the TACC user portal https://tacc.utexas.edu/portal/dashboard
• Click Manage Account
• Click Manage multi-factor Authentication
• Click unpair
• Use the email option if SMS doesn’t work
• Follow the directions in the email to unpair
• Use the Manage multi-factor Authentication button again to re-pair your cell number

Migrating Existing Arctos Accounts

1. Log in to your existing and open Operator account in the usual way on Arctos.
2. Follow the TACC authentication option on the ‘success’ page.
3. Authenticate at TACC (You may need to accept TACC Terms of Use)
4. Success! In the future, simply use the TACC option to log in.
