Cannot push to github repo

My repo: https://shadyabhi@github.com/shadyabhi/learnajax.git

Now, I cant push into my repo. I have checked the github.token its the same as my Account Settings. Ofcoarse, I am entering the right password but I get this error.

I was having a similar issue pushing my origin with the correct user and password. It turned out that I had turned on 2-factor Authentication and had forgotten. If you have 2-factor Authentication enabled you will need to create an application specific password to push your repo. https://help.github.com/articles/creating-an-access-token-for-command-line-use

There is some issue (if using https) if username contains "some" special characters.

As I understand it, github.token (and github.user) aren't used by git HTTP transport - they're only there for other tools that use GitHub's API, such as GitX and GitNub.

I think the "Authentication failed" error must be due to you entering the wrong password. (This should be your GitHub password rather than the password to your SSH private key.)

I have hit the same problem just now. Apparently, when you use git in command line, it wants you to enter the access token instead of password. This is really weird, but it works.

$ git push origin HEAD
Username for 'https://github.com':        <--- your username here
Password for 'https://t7ko@github.com':   <--- access token here O_O

PS: This is the instruction on creating token: https://help.github.com/articles/creating-an-access-token-for-command-line-use

I had just same problem as previously described. Passwords with #, ¤ or " didn't seem to work, whatever I tried.

Seems to be more or less similar problem as with Microsoft Office 365 portal, where you can't use ex. ¤ character in password, if you are going to use mobile devices as well.

Github login works fine with all passwords, in web... but using whatever client, it doesn't.

If your password contains special characters, git push won't work in Terminal. My workaround is open up emacs and do git push inside eshell.

if your username or password has special characters, you can replace it with the encoded for example, if your password is "test@2010", you will write it as "test%402010" and the config command will be like this git config remote.origin.url https://{username}:test%402010@github.com/{repo_username}/{repo_name}.git
