Since several months housands of email accounts have been hacked, How can you know it? Simple, You receive an email from Yahoo and notifies you that they detect a login attempt with valid password to your Yahoo account from an unrecgnized device and the Localization is Poland
They suggest you to change your password and activate a SECOND sign in verification with your mobile phone.which is the most STUPID suggestion!!Hello? Yahoo is not capable to keep your private information DO NOT add more private information to your account!
You receive an email like this:
Choose the option Change your password and you'll see this screen
Request to change the pssword and the type it and then you will see this screen
If you have a little bit of time and search the IP you will find something like this:
Yahoo knows it but users are still being hacked.You only need a free acces IP app to see all this, WHY Yahoo does nothing?
