Unexpected pop-up “Sign-In Required“
I keep on getting the above unwelcome prompt on my iPhone X (iOS 12.1). It seems to have been triggered by the Grocery Gadgets app: it always appears when I start GG, but also with monotonous frequency (every 5 to 10 minutes) after I have terminated GG.
There is no reason for GG to ask for this. My gut instinct says someone is phishing.
Whereas I use my e-mail often to sign in to services, each one has a different password. I have literally hundreds of passwords (thanks to 1Password).
How am I supposed to know which password is being asked for? And by whom?
Does anyone have any insights?
Regards,
Steve
