What does account linking mean?
Account linking allows you to connect multiple identity providers (such as email, Google, and GitHub) that use the same email address to a single Console account. For example, if you initially signed up for Console with a Google account, you can later link a GitHub account or an email/password login to the same Console account.
How does it work?
To initiate account linking, log out of your current account and start the sign-up process with the identity provider you wish to link. During the sign-up process, you'll be given the option to link the accounts.
