I found in the MacRumors article that IOS 16 will let to use third-party two-factor authentication apps for auto-filling verification codes. But I can't find any specific information about auto-filling verification codes, and also can't find any API to implement it on my App. Also, I installed IOS 16 beta 4, and installed apps that are on the screenshot, and any of the apps don't show me on "SET UP VERIFICATION CODES USING" field. So somebody has information about this feature and API which need to implement?

An app will appear in this list if it registers itself as a handler of the otpauth URL scheme. Once you do that, you should be good to go. 🙂

By the way, we've also received a report that this section has disappeared from recent betas. If your app is registered to handle that URL scheme and you're still not seeing this section at all, you're probably also encountering that issue.

It is still unclear how it supposed to work. Each of these applications can generate different codes. So will this just start the corresponding app? Or are they supposed to communicate with the requesting app? Is there an API for that?

I can confirm what @erynrwells is saying. I registered my app as a handler of the otpauth URL scheme and it used to work just like in the screenshot, and it has disappeared. I wrote the report they linked to. The way this is supposed to work is that it's simply for setting up codes, not filling them. Meaning, if you click on any button or url that links to otpauth:// it'll directly to whichever app you have selected. However, in addition to that list being gone now in Settings, apps that previously had buttons such as "Open with an authenticator app" buttons are gone now too in the beta. @erynrwells The way you wrote your response suggests that perhaps you're not seeing the issue and we are? Can you confirm if that's the case? Hope this gets resolved soon.

@erynrwells Is it possible to get any feedback on this? My original report: https://developer.apple.com/forums/thread/711933 and my feedback assistant post: https://feedbackassistant.apple.com/feedback/11176810 have faded into obscurity with no responses. I'd really just like to know if this is a bug that will get fixed, or if it was intentionally removed since it's been gone for so long. Thanks in advance if you can help shed some light.
