I had the same problem. I was able to reset the account and get a new QR code through https://www.msecure.com/request_password_start/
be carreful it will delete all the data of your previous account
Thank you for the post Benjamin! Were you able to get access to the QR code for your account Xiping?
I made an order of mSecure for $21.99. but, I need QR code to lock in. Can you send me QR code? Thank you!
