TACC:MFA

From TAMU HPRC
Jump to: navigation, search

Effective on September 27, 2016, all users must authenticate using Multi-Factor Authentication (MFA) in order to access TACC resources. MFA adds an extra step to the login process, requiring an additional ‘factor’ other than a password to log into a machine. A factor may be:

· Something the user knows: a password

· Something the user possesses: a mobile phone, or hard token

· Something the user is: fingerprint or other biometric scan


MFA typically requires users to provide two or more of these factors to authenticate. Adding another factor to the login process creates a layered security, making it far more difficult for an unauthorized user to access a resource. This provides a higher level of security for themselves and the user community as a whole.


TACC users may NOW set up MFA on their accounts in one of three ways:

1. The TACC Token app

2. SMS (text) messaging

3. Possession of a TACC Hard Token

Access to TACC resources through MFA will become mandatory effective Tuesday, 27 September 2016, but users are strongly encouraged to start using this method of access as soon as possible.


Users who utilize automated, non-interactive workflows will be affected by the implementation of MFA. These users should establish contact via the TACC Consulting System or XSEDE ticket system for advice.


Also: Note that setting up MFA for your TACC account is different than the DUO MFA solution recently announced by The University of Texas at Austin and the NSF XSEDE project. Neither DUO option will work when trying to directly connect to TACC resources. XSEDE users connecting to TACC resources via the XSEDE Single Sign Hub will NOT be required (for now) to set up MFA on their TACC accounts.


Please submit any questions you may have through the TACC Consulting System or XSEDE Ticket System.
