First of all, am completely unsure whether this is the correct place to post this question......
By sheer chance, I looked at my husband's email account a little while ago and discovered an email from Google saying his Google password had been changed and his account logged into via an iphone. My husband does not have an iphone, only an old Google Android phone which he uses for internet only.
I wan't sure that the email was genuine at first. I did however try to log into his account on our desktop computer (I do not think he is normally ever logged into Google on there) and managed to do so okay and to change the password, so this at first seemed to comfirm my doubts about the authenticity of the email. I then noticed that the name of the account holder had been changed from my husband's to another person's. I checked who had logged into the account and the IP number revealed that it was somebody from the US (we are in the UK).
I have now added my husband's mobile number to the account for additional security. As the password has now been changed, is everything now okay or should I do anything further please?
