How do I switch the Google or GitHub account I use to log in to DigitalOcean with?

You cannot switch directly between accounts from the same SSO provider. Instead, you’ll need to switch to a different login method, then switch back. For example, if you want to use a different Google account for SSO, change your login method to either email and password or GitHub. Then, change it back to Google and select the account you want.

Switch from Google or GitHub SSO to the username and password sign-in method on the My Account page.
Try to restore access to your GitHub account by following GitHub’s account recovery process or 2FA credential recovery process.
