You can find both the HTTPS or an SSH URLs for cloning a repository on GitHub. With this approach to account management, you store the credentials for one account to use for HTTPS connections and upload an SSH key to the other account to use for SSH connections.

The protocol you use to clone a repository determines which credentials your workstation will use to authenticate when you access the repository. Git can use either the HTTPS or SSH protocol to access and update data in repositories on. If you contribute with two accounts from one workstation, you can access repositories by using a different protocol and credentials for each account. Contributing to two accounts using HTTPS and SSH #

Other people can invite the account to contribute to both individual repositories and repositories owned by an organization, and the account can be a member of multiple organizations or enterprises. With a single personal account, you can contribute to a combination of personal, open source, or professional projects using one identity.

If you aren't required to use a managed user account, GitHub recommends that you use one personal account for all your work on. Management of two or more accounts can increase the chance of mistakenly leaking internal code to the public. Warning: Be mindful when you use one workstation to contribute to two separate accounts.
