Your usual PC FUD...
Valve was one of the first gaming platforms offering two-factor-authentification since 2011. If some unknown PC / browser tries to log in with your account data, you get an eMail with a security code (additional to the login password). As long as your eMail address doesn't get compromised at the same time, you are on the safe side. You have also the option to get these security codes to your smartphone (Steam Guard Mobile Authentificator), but there is the risk that you get logged out of your own account if your smartphone gets lost or broken.
Microsoft (and Apple and Google) followed in 2013: http://majornelson.com/2013/04/19/using-microsoft-two-factor-authentication-with-your-xbox-live-account/
Sony however doen't seem to care despite their hacking history... personal data of 77 million accounts (unencrypted names, address, PSN login details, email addresses and encrypted credit card details) have been stolen in 2011.
There have been several petitions to Sony to add two-factor-authentification as option (its usage doesn't have to be mandatory): https://www.google.de/search?q=sony+two+factor+authentification&ie=utf-8&oe=utf-8&gws_rd=cr&ei=WpZ-VoOQIcexa4CGrrgC
And Nintendo probably doesn't even know that 2FA exists ;)
