Recent Authentication Changes
The Git web interface uses NCSA authentication through CILogon. This strengthens Git authentication by: 1) enforcing NCSA DUO for web access, and 2) using authentication tokens instead of passwords.
NCSA passwords can no longer access repositories. Instead use personal access tokens to authenticate with Git over HTTPS.
Information about other version control options at NCSA is at https://wiki.ncsa.illinois.edu/display/ITS/Version+Control+Tracking
