Toward Better Master Passwords

You should try 1password. It really like it. It syncs via wifi or dropbox.
I use a similar system, except that instead of remembering randomly choosen words I use pwgen to generate a string of symbols and then construct a story from them (human brains are pretty good a remembering stories.
Say I get IJC8M9yh I would then make a sentence like Ingrid, Joel and Carol Ate Margriths 9 year horse.
(The example given is more tricky than most, since I had to add an extra word). The idea is to take each letter and convert it into a word, leaving numbers and special characters as they are (or use them creatively, as in the example above) and if the letter is a capital letter, use a proper noun in the sentence.

Like many who got bitten by Gawker, Sony, Mt.Gox and whoever else, I researched better alternatives. I found these options for password management utilities:
- 1Password
- KeePass
- LastPass
- PasswordGorilla
- pwgen
- pwsafe
- SuperGenPassword
Nice summary. I wish I had seen it about a month ago when I spent an afternoon hunting through comments here and elsewhere looking for alternatives to 1Password. (No Linux or WebOS is my main issue.)
I see that you're using SuperGenPass. I loved and used the SGP bookmarklet for a while, but stopped when I read this article: "SuperGenPass is not that secure"[1]. Read the article, try the demo, then STOP USING THE BOOKMARKLET! Because of how the bookmarklet interacts with the page DOM, other scripts can read your password!
Now this doens't mean you have to stop using SGP. I still use it, mostly with the excellent Chrome extension (SuperGenPass for Google Chrome™ by Denis[2]) or the SPG mobile page[3] (which can be saved for offline use). Both of these compute the password without interacting with any other pages.

Thanks!
I agree, there are a few issues with SGP I would fix: It fails badly on Change Password forms, it uses ~10-iteration MD5 hashes which are easily-reversible today, and the default character set for the generated passwords is not great.
I feel I'm still in the "research" stage where I want to see if I can survive with using something like SGP. I'll definitely switch over to the extension from now, though.
Side note: It's probably not a terrible idea to still maintain multiple master passwords for really-important vs throw-away accounts.

I use KeePass and synchronize the database file through Dropbox. I can recommend this combination, it works well both on my computers and (Android) phone.
The downside is that I sometimes have to enter the master password on my phone's on-screen keyboard, so it is probably shorter than it should be.

Yeah, except for the whole Dropbox making passwords optional thing. I asked AgileBits about this and they have stated that only syncing via Dropbox is supported at this time.
I very much want to find an alternate sync solution. I think it is kind of pointless to have a secure password solution if the underlying sync is insecure or more accurately has a dismal approach to security.

I don't know... why should I worry about Dropbox security in this context? The risk that someone could steal my Dropbox data is of course there, but that they then would be able to decrypt the password database (or bother to spend resources on trying) seems very unlikely.
The only thing I'm a bit worried about is accidentally deleting or corrupting the password file, as Dropbox could then synchronize this change across all devices. I guess I should back it up regularly to non-Dropbox folders to avoid losing all my passwords.

Dropbox would keep the old versions.
Unison works okay for me between laptop<->desktop. I don't think there are mobile clients, it is nowhere near as comfortable as dropbox, requires a crontab entry, and sometimes requires CLI intervention when there's a conflict.
But it's the best I have found to get folder-sync for sensitive stuff (my notes folder) without relying on a 3rd party for storage or security.

I've been using an svn for this purpose. I can sync my password dp (and config files, project files, etc.) between my computers and n900 pretty easily. It's not quite as easy as a dropbox-type of synchronizer but it has some added benefits too (history, pretty much all platforms support svn, so on).
This article's advice is good, but is overkill for most purposes. That being said, using something like dicewords, but replacing one of the words with something NOT on the list sounds like a pretty good fit for maximizing the ratio of entropy to ease-of-memorization.
Password Gorilla: https://github.com/zdia/gorilla/wiki
I almost didn't look.
Password Gorilla is a Tcl/Tk application
I can't speak to the efficacy, security of the program, but I found that bit interesting.
I'm about ready to pick up Tk, again, because it looks good enough (for me) and I'm tired of dicking around with UI crap.

Doesn't look like the link works now - 'Error establishing a database connection'
I have been moving to LastPass, but the service, as nice as it is, just has too many controls, and is a bit ugly. It also only support Mobile Firefox if you have the premium subscription (not a huge price to pay, just another barrier for me). My biggest issue with it is that I will need to set up a premium account for my wife as well, since there are some shared passwords (e.g.: our banks, utilities, etc.) and some that are individual (work-related).
Ideally, what I'd love to find is a cross-platform (mobile, UNIX, Windows) system that syncs data over ssh to a server I specify.
Really ideally, I'd love if everyone adopted OpenID, so I can just maintain a single access point that I secure to my satisfaction (client side certificates, one-time passwords from hardware tokens, etc.)
