On the Microsoft authenticator it only recognised one code even when I scanned each of the bar codes individually ( I scanned all 4 and with each scan it recognised the key being linked to Elysium project and my in game username)
On the Duo Mobile It created 4 seperate keys, one for each scanned bar code. I tried each one individually at login but none worked.
I tried uninstalling the apps and then re-scanning but it didn't make a difference.
