Express (trusted) login, can we have it?

[Kaes]

The reason you are able to login to Destiny without entering a username or password is because Destiny relies exclusively on console platform logins for user authentication and player identity, which is why the name shown above your Guardian is your name on PlayStation®Network or Xbox LIVE. Furthermore, there is no PC version of Destiny.

On the PlayStation console family, Final Fantasy XIV uses your PSN℠ login in addition to your Square Enix username, so it is possible to do a similar login method. However, a large number of FFXIV players are on PC, and unlike game consoles, PC clients are frequently infected with malware and there is no method to adequately secure saved credentials on a PC client.

Allowing faster login for players who are using a console does not benefit every player and could create bigger problems for Square Enix if such a system were to be misused.

I have also wanted a feature like this, but on second thought I can see how this would be tricky.
