What password does it want?

14:32:10.592 gui1_b2_id is not found in Keychain/Keyring
14:32:10.594 gui1_b2_key is not found in Keychain/Keyring

This is what I see, but when I first installed and ran duplicacy, it said something like “this program wants your personal data” (or something like that) and then I tried to type in any password I can think of, but nothing worked. I created a randomly generated (by my computer) password to log in to duplicacy, and I can’t retype it. How can I restart and get backing up?
