On Stack Exchange's Add Login Credential page, one can add logins with Google, Facebook, Yahoo, etc. How many logins should I have to provide best combination of:
- The least chance of a hacker gaining access to my Stack Exchange account.
- The best recovery in case they do.
One? As many as possible? My possibly incorrect assumption is that I should have two. That way, there are fewer sites that can be hacked into to gain access to my Stack Exchange account; but if one of the two does get hacked, and, for example, its password is changed, I'll still be able to regain control of my Stack Exchange account with the other site's non-compromised account.
