I created a new github account but now I cannot upload my coding projects to my new github account through the bash command line

Everything looks like it is going well until I reach step 5 up the standard uploading process for github. when I type “git push -u master origin” on the command line of MINGW64 it returns "remote: Permission to user1/weather-search-api-app.git denied to user2.
fatal: unable to access ‘https://github.com/user1/weather-search-api-app.git/’: The requested URL returned error: 403. "

Do I need to download MINGW64 command line github bash again and configure it to my new github account? Do I also need to delete my existing MINGW64 command prompt that is configured with my old github account?
