Your Google Account password has been changed
In order to help keep your account secure, Google sends you a notification any time your password is changed. If you made this change, you won't need to take any action.
If you receive a notification regarding a password change that you did not make, your account might have been hijacked and you should follow the steps to reset your password. To keep your account secure, make sure to choose a strong password.
Message and data rates may apply. If you don't want to receive these notifications on your phone, change your security notification settings.
