I use 1Password as a password vault. Some years ago, I decided to start lying for secret question answer challenges. I use 1Password to generate a string of garbage (without numbers or symbols, 25 characters long) and keep that answer in a custom field in the 1Password vault. I've tagged those entries with a security tag to find all accounts with secret Q&A information.

I am paranoid about back ups because if god forbid I lost that vault, there are accounts that would be permanently lost to me.
