On XSEDE, what is Single Sign-On?

Single Sign-On (SSO) authentication on the Extreme Science and Engineering Discovery Environment (XSEDE) is based on Grid Security Infrastructure (GSI), part of the Globus toolkit.

SSO authentication allows you to access your accounts on various XSEDE digital services using one username and password combination. This XSEDE-wide login is the same as your XSEDE User Portal username and password.

Note:
NICS digital services: If your XSEDE allocation includes time on a digital service at the National Institute for Computational Sciences (NICS), you won't be able to access that system using your XSEDE-wide username and password until you activate your NICS account. Additionally, SSH access to NICS digital services requires the use of RSA One Time Password (OTP) tokens, which users receive in the mail after activating their accounts.

TACC digital services: If your XSEDE allocation includes time on a resource at the Texas Advanced Computing Center (TACC), you won't be able to use your XSEDE-wide username and password until you have activated your TACC account. TACC will email you a welcome message that includes a link to the TACC User Portal and instructions for activating your account.

Additionally, once you authenticate using SSO, you can connect to your accounts on other XSEDE digital services without re-entering your XSEDE-wide password.
