Hi. I have a favourites bar on google chrome. I sign into something using my email address. Don’t fully understand this because... I used a different computer to search the web. I was asked to sign in to a google account. I was told to check my Lenova tablet M10. I struggled with that as I never really use it. I thought it might have been sent to my email address but it wasn’t their. How can I get control of this? I need to use an email address or get a text message on my mobile phone. How can I change my details? Email address, mobile phone, device and any way to verify myself. There is no phone or email support or anyone to contact over problems. I will want to change my email address and phone number.
