Let's say alice
is a github.com user, with 2 or more private repositories repoN
.
For this example we'll work with just two repositories named repo1
and repo2
https://github.com/alice/repo1
https://github.com/alice/repo2
You need to be to pull from these repositories without entering a passwords probably on a server, or on multiple servers.
