I shared read-access to a repo through my "manage_account" settings. However, under the other account, if I run git clone, I am asked for a username and password. I am unclear how to proceed.

Scenario: Would like to share a project, include allow people to look at the source code.

More precisely:
As an admin (nancy@curoverse.com) I shared my repo with non-admin (nancy.ouyang@gmail.com), however I cannot clone that repo. (see pictures)
