How to create a new GitHub account with the same email address?

The simple answer is NO. You can't create more than 1 ID in GitHub by the same email, but you can do it by using multiple email IDs.

If you try to do it, GitHub will show an error - "email invalid or already taken", so delete the present account or make it with a new email id .

I know this is an old post but it still shows at the top on a Google search on this subject.

Some email providers support using special characters to use multiple email addresses that map to a single account. For example, if you use Gmail and your email address is [email protected] and you already have an account on GitHub with that email you can create a new GitHub account using [email protected]
