How to change github username

GitHub is the world's largest open source code hosting platform, which allows developers to store, share and collaborate on code development on one platform. When using GitHub, each user has a unique username corresponding to them. Sometimes, we may need to change the GitHub username, for example, because the username is not personalized enough, or because a more authoritative username has already been registered.

So, how to change your GitHub username? The specific steps will be introduced below.

Step one: Log in to your GitHub account

Before changing your GitHub username, you first need to log in to your GitHub account. If you don't have an account, you can register one on the GitHub official website. The operation is very simple.

Step 2: Enter Settings

After logging in to your account, click on the avatar in the upper right corner and select "Settings".

Step 3: Modify username

In the "Settings" page, click the "Account" tab, then find "Username" and click the "Change username" button. Then enter the new username and click "Update username" to complete the change.

It should be noted that the GitHub username can only contain letters, numbers, dashes, and underscores, must start with a letter, and cannot be shorter than 2 characters or longer than 39 characters. In addition, if the new username is the same as another user's username, GitHub will automatically prompt that the username cannot be used.

Step 4: Update the local warehouse

If we use Git to manage the local warehouse and synchronize it with GitHub, we need to update the local warehouse after changing the GitHub user name, otherwise the synchronization will fail.

Updating the local repository is very simple, just use the following command in the Terminal:

git remote set-url origin git@github.com:NewUserName/NewRepo.git

Among them, "NewUserName" is our new GitHub user name, "NewRepo " is the name of the local warehouse where we execute the command.

It should be noted that you need to change the "OldUserName" in the original "git@github.com:OldUserName/OldRepo.git" to the new user name, otherwise you will not be able to submit the code normally on GitHub .

Summary

Changing your GitHub username is a simple process. You only need to log in to your GitHub account, enter the "Settings" page, and modify your username. If you use Git to manage your local repository, you also need to update the local repository. Of course, we do not recommend changing your GitHub username frequently, as this will cause great trouble to other developers. You should only consider changing your username if necessary.
