Different SSO Options/Account Linking Methods

At some point, may we get different SSO options for logging in or using F&F? Being able to use Google is nice and all, but I’m slightly worried about potentially losing access to my F&F account if anything ever happened to my Google one. Would it be possible to add account linking, or just some kind of local sign-in methods that would make securing our accounts a bit more robust? Just something to serve as a safety net in case something happens to our primary sign-in method.
