I use 2 factor authentication for any service that supports it,and I noticed the several of them generate single-use "backdoor" passwords that they recommend for you to print out and store someplace secure. That's not a bad system at all.
To my knowledge, the way 1Password currently works precludes the existence of a backdoor password scheme. So I'm looking for ideas on how to insure myself against forgetting my master password and having to rebuild my 1Password Vault. I don't think that I'll every forget it, but let say I get hit by the proverbial bus and my relatives need to get access to it to settle my estate. What would be a good setup to give them access to my vault?
Please chime in with your ideas! It could be print and store, it could be to store it in another password manager, store it as encrypted text in Evernote, whatever.
