I hope Glenn will address this question in a Q & A session.
FYI: I don’t think I used a real address when I created my Bitwarden account early this year. Sadly, I don’t know which address I used and now I can’t log in to my Bitwarden Vault to change my master password. I’ve searched and found that I didn’t receive a confirmation email from Bitwarden which would solve that matter. I’ve tried every real email address and all the anonaddy addresses I created when I first started this privacy plan journey. And I’m traveling right now.
The Takeaway: Wjatever you do, be sure to keep your account login email with your master password!
