What you need to know

Initially I had the same issue once connected to my iPhone......App said your connected with allowing me to pair my bluetooth Titan Key. Log into your google account on a computer and activate Advanced Protection and follow the required steps. Once complete, go back to the app and it will allow you to setup your titan Bluetooth key to secure your iPhone.

Advanced Protection Enrollment Misleading

I did a lot of research and ended up purchasing the YubiKey 5 NFC and Security Key NFC from Yubico’s website. I was really excited to use them to better secure my account. Unfortunately, due to the limitations of Google’s iOS apps, the Bluetooth “recommendation” is an unstated requirement. Nowhere during the enrollment process for the Advanced Protection Program does Google say that their apps only support Bluetooth-enabled U2F keys when using iOS. YubiKeys only support Yubico OTP over NFC for iOS. Google really should make an effort to detail its full compatibility, or in this case, incompatibility.

Run while you can...

The Google Advanced Protection and Security Keys are not worth the headache for the vast majority of users. Unless you have a business or corporate account, save your time and your money. This “app”, or (to be more precise) the product it is supposed to enable, breaks everything: Google Home, Hue Lights, Chromecast... the list goes on. It’ll be a week before it’s all fixed, I won’t be able to use the vaunted “advanced protection” and I doubt I can get my money back.
