> It is impossible to absolutely prove that our answers to the easy questions above are truthful. But what I can do is provide a number of more verifiable claims, each of which makes it harder for us to lie about any of this. In combination, these should be enough to persuade you that there is no backdoor (deliberate weakness) in 1Password and that it would be very unlikely for one to be introduced.
Great post, and about as much as anyone can hope for. (I was glad to see this because I looked at some of the other 1Password like offerings and they are, erm, not good.) While the post doesn’t give me 100% confidence it gives me enough to feel comfortable staying with AgileBits products for the time being.
