seems a bit redundant:
"What authentication methods are allowed?

The Git Connector supports both SSH authentication and HTTPS.


Is communication with Git Connector secure?
Communication is over SSH or HTTPS. The Git Connector can communicate with Helix over SSL.


How does the Git Connector handle authentication and authorization?

The Git Connector uses SSH keys to verify your identity, and matches your Helix user account and public key to that stored in the Helix server and the Git Connector.
HTTPS checks the user name and password against the Helix user name and password.

In addition, the Git Connector will check the permissions of the user."
