Add option to bypass 2FA when using SSO with 2FA

Example: If I have 2FA enabled on both my GitHub and Glitch accounts, I would be able to sign in to Glitch using GitHub with just the code for GitHub, without having to enter one for Glitch as well. However, sign-ins using an email link or a password would still require it, as well as any SSO accounts that don’t have 2FA enabled.
