Just got a flash up on my iPhone saying someone in somewhere in China (it came up with place name and location on map) is attempting to log in using my Apple ID. It asked me to allow or reject so I clicked reject and then it definitely asked for my passcode before allowing me to change password.
Can't remember if it asked me twice for authentication but now I'm panicking it was a scam? I have since changed my password again but should I be worried about this?
