I'm looking for someone who knows what they're talking about when it comes to Internet security in general and Mac OS X Lion in particular to help me out with some advice here:
Since Mt.Gox's re-opening, I have started using a complex, un-memorizable, and barely typable new password. Since their security issues, it seems like they have also shortened the idle time after which they log you out to some unbearably short few minutes and it is driving me absolutely crazy trying to re-login with this password what seems like 50 times a day.
I recently upgraded my Mac to Lion and Safari v5.1 and I noticed a new feature where it offers to save your passwords to secured websites. (Yes, I realize other browsers have offered this for ages, in fact I think older Safari did as well, but it looks like this has been reimplemented in v5.1 to actually store the password in Keychain.)
I have a fairly rudimentary understanding of Mac OS and Safari internals, but I believe that Keychain is considered quite secure. However, with all the shenanigans around with Mt.Gox accounts getting hacked and Bitcoins getting stolen, I'm a bit nervous about storing this password right in my browser.
