The worst offender for me is the Costco mobile app. It's handy because it allows you to enter the store by scanning the QR code it displays on start up. However it also nags you to create a passkey. You can dismiss this by saying that you want to keep using a password. But then it nags you again next time. This behavior is problematic because the delay between opening the app and the "create a passkey" splash dialog (which hides the QR code) is exactly the time it takes to pull the phone out, open the app and present the screen under the reader at the door. Every single time I need to look back at the phone screen to see why it didn't scan, dismiss the passkey nag, bring up the QR code again, scan.
