I am a collaborator in one the private github repository. I am able to fork it but when I try to clone it onto my system, it shows a pop up box asking for credentials and even if I enter correct credentials I can't login.
Is it just me or github actually doesn't allow cloning of private repo even if I am a collaborator in it?
You can clone it over HTTPS
git clone https://github.com/privateRepo/privateRepo.git
The prompt will ask for your username password/Authentication Token.
or
git clone https://username:token@github.com/user/repo
Note :- Support for password authentication was removed [link]. Please use a personal access token instead of password if it does not work.
If you can fork it, you should be albe to clone it.
even if I enter correct credential
Make sure to use a PAT (Personal Access Token) as your password, instead of your actual GitHub account password.
This is because of "Token authentication requirements for Git operations" from Dec. 2020.
