The embedded MFA signature embedded into the generated QR Code should be unique for each site
I use Microsoft Authenticator for my MFA configurations. When presented with a QR Code to scan, there is a text signature identifying the site, and a secret. The text signature should be unique to the site, allowing for different codes to be generated for each site.
cloud.screenconnect.com is one site
mycompany.screenconnect.com is another site.
I have have attempted to set up a record for each site, only to accidentally lock myself out of cloud.screenconnect.com.
I set up cloud.screenconnect.com first. I then set up MFA for mycompany.screenconnect.com
Because the signatures used for the two sites are the same, one overwrote the other. This locked me out of cloud.screenconnect.com.
I don't like the idea of having a common secret between the two sites. Either site requires its own login with a different password. It is obvious that the secret for Authenticator should be different too. So the text signatures between the two sites should also be different.
