You can't scan the QR code with your camera outside of mSecure. mSecure will prompt you to scan it when it's needed during the app setup process.
Go ahead and download mSecure if you haven't already, then open the app. After you open it, go through the screens until you asked to Sign In or Sign Up. Choose to Sign In and then enter your account's email address and your password. After that, if needed, you will be asked to authenticate as the owner of the account, and you'll choose the option to scan the QR code.
I have 6.0.7 not v5, all I had to do was sign in with my old password and then put in my new password. It now works fine.
That's great news John. Please let us know should you need further assistance.
