git push origin main
When I tried to push my repo,
Permission to my_repo.git denied to my_githup_username. fatal: unable to access 'https://github.com/my_githup_username/my_repo.git/': The requested URL returned error: 403
A error like above occurs. The solution is quite simple.
git remote set-url {remote_name} https://{my_githup_username}@github.com/{my_githup_username}/{my_repo}.git
Enter the command above. Then the browser asks you to log in. After login, try push again. Then it works!
