Some time ago I set up an account with Trello under one email address. When re-invited to that board yesterday I tried to log in, but was stopped by the need for a code from Google Authenticator. I don't have an entry in Authenticator for Trello, so that failed. I don't have a 24-character recovery key. And when asking for the next step, to have instructions emailed to me, It has been over 24 hours and I have not seen any such email show up.
I have (apparently) an account also under a different address, and that is what allowed me to access the Trello board to which I was invited.
How do I get Google Authenticator set up for the original address if I can't log into that account? Or, can I merge the old email with the other one that works?
