My home network, windows 10 pc, and Iphone was recently hacked. I have been (and am continuing) working with my wireless carrier and my ISP to resolve it all. I Just a few minutes ago signed back into gmail account via the gmail app for the first time in over a week, and after the genius bar wiped my devices clean & reinstalled software; and after my phone number and sim card have been changed. I have been checking all of my gmail account settings to secure the account. after being logged in for 29 minutes someone else logged in on an iphone located in the city where I live. I investigated and indicated to google I didnt recognize the device so google signed me out of it. Next I saw 2 additional active unknown devices signed in - 1 being an ipad and 1 an iphone - neither are mine. Both of these say IOS Account Manager. Interestingly, I just now noticed under my iphone's active connection it has my correct iphone name, correct location and says IOS ACCOUNT MANAGER underneath! under that there is a checkmark indicating this iphone connection is the phone I am currently using!
I do not know what this IOS Account Manager is, but it might explain why the passwords on many of my other (non google related) are "incorrect", and do not work. I use a password manager and always make changes to passwords inside the password manager. I know someone has been changing my passwords - I am not sure how. maybe this IOS Account Manager is the culprit - if I only knew what it is!!
I will continue following this thread and will post if I find out anything new. Incidently last night I changed my wifi network name and password, signed out of wifi then signed in again to make sure it was working. This morning the password was not recognized so I have updated via the router, signed out and am now signed back in. If it gets changed again I am going to scream 🤬!
