Notifications Buggy

Generally a reliable authenticator, however either a recent app update or iOS update, or both, prevent the app for notifying the user properly on iPhone iOS. Checking the notifications settings for the app, it appears it has very limited configuration settings as compared to other apps.

Used to work with the Apple Watch notification so I could accept it from my wrist hasn’t worked in months.

Needs a watch version

Seriously, add watch capability!

No more Apple Watch or lock screen approval

I used to be able to approve login from my Apple Watch or directly from the phone notification on the lock screen. The more recent updates have removed this very useful feature.
