Other data.
Yes. Authenticator App Secure 2FA's developer declares other data as data used to track you — data that can be combined with other companies' data for targeted ads or ad measurement, or shared with data brokers. On iPhone you can refuse: tap Ask App Not to Track, or switch off tracking requests for every app in Settings.
What “tracking” means on an iPhone
Apple defines tracking as linking data from this app with data from other companies' apps, websites or offline sources for targeted advertising or ad measurement, or sharing it with a data broker. It is narrower than “collecting data”: an app can collect a lot without tracking you, and a small app can track you with a single advertising SDK.
Since iOS 14.5, App Tracking Transparency requires every app to ask before it accesses your device's advertising identifier or otherwise tracks you. The App Store label is where the developer declares which of its data is used that way. Authenticator App Secure 2FA declares 1 data type, so expect the “Allow Authenticator App Secure 2FA to track your activity across other companies' apps and websites?” prompt.

How to stop Authenticator App Secure 2FA from tracking you
- When Authenticator App Secure 2FA shows the tracking prompt, tap Ask App Not to Track.
- Already said yes? Open Settings › Privacy & Security › Tracking and switch off the toggle next to Authenticator App Secure 2FA.
- To refuse every app in one go, switch off Allow Apps to Request to Track on the same screen. Apps then cannot ask, and are treated as if you declined.
- For Apple's own ads in the App Store, News and Stocks, see Settings › Privacy & Security › Apple Advertising and turn off Personalised Ads.
- Inside Authenticator App Secure 2FA, look for an analytics or personalised-ads switch in its own settings; it covers data the iOS switch does not.
