Stop using one password for everything then. A manager like 1Password is almost an essential tool for the security conscious.
At first I worried about what would happen should the db file get corrupted somehow. But then I set up the backup tools with which I can keep as many backups in as many places as I want, so unless the db file gets corrupted in all places, I think I will be fine.
I'll have to give it another look, I guess.
<BTW: This goes without saying, but I'll say it anyway: Don't lose your 1 master password or your password database. ;) >
