Why github doesn't ask me for username/password?

Question

I tried to git pull from github origin and got this:

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

instead of promt for username and password. My ~/.ssh/ folder is empty, so I'm confused what publickey is meant here.

How does git decide whether to ask for username/password? How can I force him to do so? (I don't want for some reason to use ssh keys)

Answer 1

This happens because you're using SSH url and probably your SSH settings are not configured (you're also saying your ~/.ssh directory is empty).

You can check the current remote url(s) using the following command:

git remote -v

If you want to use basic authentication (username + password), you have to use https.

Do this in your repository:

git remote set-url origin https://github.com/your-username/repository.git

Replace your-username with your GitHub username and repository with the repository name. Also, replace origin with your remote name (if you're using another remote name, probably you are not).

As @Abizern mentioned, you can configure the SSH keys and use the SSH urls instead. That may speed up your work not annoying you to enter the username/password every time.

There are other alternatives to prevent git from asking for your password every time. Here is one of them, by setting the cache time.

...or you can provide your password/token in the HTTPs url, as mentioned here.

git remote set-url origin https://username:[email protected]/username/repository.git

Answer 2

Alternatively, set up an SSH key for Github.

It's quite simple - there is a full guide on the GitHub site.

This also has the advantage of allowing you to revoke the keys from the GitHub site without access to the computer. Useful if you are using a work computer.

Edited to add

I should note that GitHub recommends using https for access.
