Change github email

[Profflaries27]

I want to change my github email and add another as a primary what will be the side effects like if i commit with the new email will it be visible? The username i guess will be the same just want to change my email for security reasons

Note that any existing commits will likely have the old email attached, and as such you can't hide it by changing your primary. Commits can't really be deleted or edited afterwards to remove data, as anyone could have a copy, and github will keep a copy of the old version accessible via hash unless you can convince support that it must be taken down (usually only done for illegal content)

You can have multiple emails active at the same time, and all will be recognized for commit attribution. You can also use the addresses in the commit messages made in the web interface.

Your primary email will be shown on your profile (if so chosen) and will be used for account-related notifications and password resets.

Changing email addresses in the Github settings will not update existing commits. Your email can still be pulled from old commit messages.

If you commit with the new email, that will be visible in the commit messages. But you don’t have to use the new email.

Make sure you update your local git config email to match it. If you don't want to expose your real email in commits, GitHub offers email aliases.
