I was actually working on an app, for which we used GitHub authentication, and used to push and pull commits. But as you may know, it actually changes your contributions, and we basically needed a debug account to test the app, so that we can test app, without changing anything on my OG account. So let’s see how to create a new GitHub account, with the same email you have used on another account.
Step-1 Open GitHub on your PC
Open the GitHub website on your PC.
Step-2 Click the SignUp button
Click the SignUp button on the homepage.
Step-3 Fill in the new credentials
Fill entries like your username, password. And then fill your email like this -> email+1@gmail.com, which means that if your previous email was email@gmail.com, you just need to add +1, or +2 or any number like this. This is possible because GitHub will treat this as a new email, but gmail doesn’t consider this as a new email, and redirects all messages to the email@gmail.com. So we are basically using same email to create a new account on GitHub.
Step-4 Completing
Just click create an account, and voila, you have a new GitHub account, for anything that you want!
