XSEDE’s web single sign-on (SSO) process is used to login to XDMod, Jetstream’s web interface, several XSEDE web sites (JIRA, Confluence, RDR, Research Software Portal, etc.), in the User Portal’s "Other Sign In Options", and is one of the options for logging in to Globus Transfer. This web login process uses a "weblogin.xsede.org" service operated by Globus for XSEDE.
As previously announced, XSEDE has transitioned this service to the "idp.xsede.org" service. All web SSO logins using XSEDE credentials now require multi-factor authentication (MFA). Users who have not yet enrolled in XSEDE Duo will be prompted to enroll the first time they log in using idp.xsede.org. Users will continue to have the option to use linked campus identities for authentication, which may or may not require MFA.
XSEDE MFA documentation has been updated to explain this change.
The XSEDE User Portal (XUP) main login process does not use XSEDE’s web SSO and is not affected by this change.
