How to change git user in Visual Studio Code or even in command line? (Permission denied to user1, The requested URL returned error: 403)

Question

I am in VS code as a particular git user (say user1) and want to pull & commit changes from one of my other github accounts (user2). After pulling my repository & commiting when I push I get the error of type:

remote: Permission to user2/repository.git denied to user1.
fatal: unable to access 'https://github.com/user2/repository.git/': The requested URL returned error: 403

So I assume this error is simply because I am 'logged in' as user1 in VS code. But how exactly can I change myself to user2 to be able to work on this repository?

I am using Macbook. I have tried many variety of ways e.g. changing to SSH cloning & resetting git config without any luck. There has to be a very simple solution to this problem which should be very basic. I was expecting it will ask me for credentials for the second account but it never did.

Solution

Deleting github information in Keychain worked as explained here.

Although it doesn't let one use multiple accounts at a time.

Have you searched the internet for an answer? A quick Google search lead to this, which would possibly work: stackoverflow.com/questions/28238037/…

This did not work for me.

Then the only option that comes to mind is to use the command line and change users.authenticate, then commit your code.

Can you elaborate bit more? I couldn't find any tag named users.authenticate.

That was a typo on my part, sorry about that. I was saying to use the command line to change users/authenticate -- meaning to use the command line to change your user, or to re-authenticate as another user.
