@joniboini, yeah, it seems that Udrujex missunderstood my post. I heard about password management tools such as LastPass, but never tried to use it. I wouldn't feel comfortable to give my passwords to a third-party services, no matter that these passwords are encrypted. For me it's similar like online bitcoin wallets - in general it should be safe to use but I'm not a big fan of it.
I can understand your feelings. I'm still looking for another alternative too, but not yet find the perfect one. Writing down all of those passwords increase the security risk and it is inconvenience too. I really hope to have a perfect memory so that I wouldn't forget any password that I used :/
