unable to push from local to remote

[nguyen-info]

When I git push from my local repo to the remote repo, even after I carefully log in with my credentials, I'm unable to commit then push from my local repo to the remote repo. I get this error:

remote: Invalid username or password.
fatal: Authentication failed for 'https://github.com/BITS-Research/OSHI.git/'

Did permission settings change?

This was due to my failed attempt at creating an SSH key, but it is now fixed. For future reference, here's how to set up an SSH key to avoid having to type in your password for each push:

• create ssh public key by typing ssh-keygen in terminal
• create new file name. In this case, I just used github
• create or open file ~/.ssh/config to configure ssh key with ssh-keygen
• Add this text to the file. You can customize the github.com and last github instance to your preference. Something that identifies the remote server that you are connecting to:

  Host github.com Preferredauthentications publickey IdentityFile ~/.ssh/github

Note: The second and third lines are indented with two spaces.

• set up remote by typing into terminal git remote set-url origin git@github.com:repoName.git (In this case it was git@github.com:BITS-Research/OSHI.git)
• be sure to add the public key from local to github account settings. Find the public key by typing in nano ~/.ssh/github.pub in terminal
