I have attempted to remove Git's access to private GitHub repositories on GitHub. No matter what I try, I cannot stop it from gaining access. I therefore wish to know how it is authenticating, so I can remove access .
I have tried both methods here
First:
git config --global --unset user.name
git config --global --unset user.email
git config --global --unset credential.helper
and second
git config --global --unset-all
And I've also deleted every github entry in Keychain Access.
When I open a new terminal window, and push to a private GitHub repository, it asks for by username and email ( not password), yet the push succeeds.
How can I find out how Git in terminal able to use my GitHub credentials to push a change to GitHub?
On most macOS systems, the credential.helper
variable is not set in the global config, but in the system one, so you still have a credential helper enabled. You can verify this by running git config --get credential.helper
, which will probably print osxkeychain
.
If your goal is to remove the credentials, you can do that by following the steps outlined in the Git FAQ :
$ echo url=https://username@github.com | git credential reject
If you're just interested in whether the credential helper has any credentials, you can run this:
$ echo url=https://username@github.com | git credential fill | less
That will print a line containing password=
with the password. Note that in this case I've piped it to less to prevent it from being printed long-term on the screen.
Per the GitHub Docs , for macOS:
Through the command line, you can use the credential helper directly to erase the keychain entry.
$ git credential-osxkeychain erase
host=github.com
protocol=https
> [Press Return]
If it's successful, nothing will print out. To test that it works, try and clone a private repository from GitHub. If you are prompted for a password, the keychain entry was deleted.
