Hi @Nigel, there’s nothing firm yet but basically, yes.
As you’ll already know, the mobile authenticator is currently a P.O.C. and it’s sitting on GitHub. When it’s in a more polished state then we’d hopefully be looking at getting it on to the Google Play Store for Android, and for iOS we’d probably be looking at TestFlight (initially at least). That being said though, we might look at other options as well.
Is that too much of a politician’s answer?
