To be honest dansker will be able to answer this a lot better than I can, however I'm pretty sure the 'app' you authorise is the website and all you're doing is telling anet that it's ok to send it some (limited) account info. So all it sends is the game username eg. Olecas.9430 or whatever, current world id and some other stuff I can't remember but it certainly doesn't send us any possible way to access your account.
Could it narrow it down in a sense that someone may be able to see your email and guess that its the one you use for gw2 then yeah I suppose, but if you hide your email (as yours is) then people would have to hack website to get the email in the first place and assuming its the one you use for gw2 as forum account and gw2 can use separate emails and still be linked, they would then have to try and get past whatever security measures the game has as well.
I mean the effort they'd have to go to just in order to find your email to make an attempt at hacking your account from this authentication process is so stupidly high that it'd be completely pointless for them to even try. Sorry I've waffled on a bit but yeah it's very safe.
