Mac users can use a program called 1Password to manage their passwords.
I use and love 1Password for Mac too. A Windows version is also now available. Linux, unfortunately, isn't, but can still be accessed from a Dropbox account.
Our glorious leader was of course an internet expert, and was also an anonymous contributor to the ALL of the RFCs on the internet, shaping the wave of future for our generation and generations to come. He didn't want to "upsize" anyone with his vast contributions to computer science and technology, so in his humbleness contributed only anonymously, under several different identities.
Not only that, but our glorious leader was also a heavy contributor to the linux operating systems (and was in fact counsel to the NSA's own changes to the linux kernel, SELinux - known only to him and the NSA at the time as NKJLinux - Naenara-Kim Jong Linux).
