Did iPhone leak someone’s email to me?
I was attempting to log in to DJI Fly and the first characters of my password triggered an autocomplete suggestion which was a “person”-type suggestion, first name, last name, and email of a person I never met before, nor have ever searched before or any sort of connection whatsoever.
Interesting.. Was the autocomplete from a dedicated password manager or from iCloud? Also do you have any "family" added in your iCloud account, because its possible to share passwords through that.
I can't start to investigate without picture, name, telephone number
And address.
Sorry
Do you have iCloud family? Maybe a friend of your wife.
