I just had this problem at work. The builtin git that ships with mac or comes when you install xcode caches git credentials in keychain. The fix for me was to:

start keychain access (start spotlight via cmd + space, type keychain, press enter)

Under keychains on the upper left, select "login"
Under category on the left, select "passwords"

find the name "github" and delete it.

github identifies you by the ssh key it sees, not by any setting from git.

Therefore, you need to ensure that your work account's ssh key is not in your keyring when you try to push from your personal account and vice versa.

Use ssh-add -l to determine which keys are in your keyring, and ssh-add -d <keyfile> to remove a key from your keyring, if it dosent work remove the 'unwanted' ssh key from ~/.ssh/config.

NB: Github will still identify your commit based on the email only.

it looks like my terminal does the commits with my username, but pushes them with the other one

Author and committer name and email (which are important for GitHub) are derived from:

git config user.name
git config user.email

However, as mentioned in git config and git commit-tree, those values can be overridden by environment variables:

GIT_AUTHOR_NAME
GIT_AUTHOR_EMAIL
GIT_COMMITTER_NAME
GIT_COMMITTER_EMAIL

So double-check those variables.

Things work back normally if I force the user in the .git/config of a repository but I don't think that's the good option.

But it should be a good solution.

When using an https url, I always specify the user in it to make sure the authentication is done with the right user.

http://USER@github.com/USER/REPO.git

If you are using MAC, then go to Keychain Access and remove the entry of the user for which you don't want git access.

A temporary solution is first run killall ssh-agent then add the ssh keys generated for the account you need to use ssh-add ~/.ssh/id_4shameer

It will help us to work on multiple github account when we will get the error of type ERROR: Permission to user/repo-git.git denied to username.

The solution for me was to add an entry in my ~/.ssh/config file for github. I had to do this because:

1. I had multiple github accounts with the same key (don't do this!)


2. when you 'git push' using ssh, your computer grabs id_rsa by default and uses that as its ssh identity.


3. github can't (unsurprisingly) deconflict which account you mean, since it's basing the account off the key it is presented, which if tied to more than one account, leads to pain like this. The killer is, for a long time, I was getting away with this and things just worked out.

The entry I added is:

Host github.com
 Hostname github.com
 Port 22
 User waterproofpatch
 IdentityFile ~/.ssh/id_rsa_waterproofpatch

I had created a new key, unique to my account, as id_rsa_waterproofpatch. This entry in my ssh config specifies that for connections to github.com, I wish to present this key.

Another solution would probably have been for me to log into the other account, delete the duplicate ssh key.

I'm using Windows 10 and I faced the same issue today. In my case my credentials for different user were saved by Windows Credential manager. Thus deleting/unsetting git credentials with below command,
git config --global --unset credential.helper

didn't help. I had to manually delete the entry in Windows by following the below way,

Start --> Control Panel ---> User Accounts ---> Manager your credentials ---> Windows Credentials

Then search for an entry like, git:https://github.com and remove it. It works fine after that.

clearing keychain didn't help... I had to ssh-add -D and re-add the key with ssh-add <keyfile>

I solved this problem removing (or renaming to *.bak) the id_rsa and id_rsa.pub file on MacOS High Sierra. Idea from here.

I have custom host redirects in ~/.ssh/config that should be applied but used wrong user before I renamed the two files...

That's what worked for me:

1. Changing the credentials inside .git-credentials


2. Changing the global user.name and user.email inside .gitconfig

What worked for me removing the repo and adding it again:

git remote rm origin
git remote add origin git@github.com:fguillen/MyApp.git

I have the same problem in windows10 even after uninstall my git, as @user542833 says it is because windows cache and you should remove Github credentials in your windows Credential Manager and when you again attempting to push, windows ask your credential and set it again
