It's really that difficult to use KeePass? It's offline, cross-platform, with password generation, secure session for entering the master password, could type passwords without using the clipboard and if you want to sync you can save the encrypted db on dropbox, git or wherever yout want.

The only problem I see is when I need a password but I can't access database, which is almost never since Keepass has a port for Android. But in those (few) cases I can write down a few notes which I can use to create a not easy to guess password for that specific use case.
