An App is asking for my iPhone passcode
I logged out of an App on my iPhone 12 Pro Max. When logging back into the App it asked for my iPhone passcode. This was not access to iCloud Keychain - it was the App asking for my iPhone passcode to access the Apps own login credentials (which, I should add were not up to date - as I had recently updated them). I changed my passcode as precaution after entering it into the App.
An App asking for iPhone credentials seems unusual to me - I have not seen this in all my years of having iPhones.
Does this sound right?
iPhone 12 Pro Max, iOS 14
