Authenticator App

When trying to set up 2FA, the panel with the QR code has a link that says "View suggested authenticator apps" but that link goes to a page that merely tells me in excruciating detail why I need to use this approach BUT DOES NOT CONTAIN ANY SUGGESTIONS as to what apps might actually be applicable to use here!

I still have no idea how to authenticate my account so I can access the files that have been placed there for me (owner has mandated authenticator app). This is about as user-unfriendly as it could possibly be!

... some time later...

I'm trying to set it up on a laptop. When I do scan the QR code it opens up Apple Keychain on my phone. Perhaps that is an authenticator app. Except that I DO NOT USE Keychain for storing website passwords on my phone (or laptop). And in any event I'd have to log in and use Box on my phone to do that. Sigh. So I did. And then once I'd manually entered my Box username and password into Keychain on my phone, and then logged in to Box.com, and then scanned the QR code again, Keychain starts generating a new verification code every 30 seconds. I've now tried several of them, to verify on Box.com on my phone, and every time I get a message saying 'invalid code'.

I'd love to raise a ticket but the one place I saw that (at the foot of the page of excruciating explanation but NO ACTUAL APP SUGGESTIONS) was a link that only took me to this community forum.

Good grief, but this is one of the worst user experiences I have had in a very long time!
