Hello. I have an elderly relative who has a Google account. Lots of his family photos of people no longer with us are stored on a Google Photos app on his iPhone. He does not remember the password. When we try to recover access to the account, a code is sent by text to a mobile phone number he no longer has access to. I cannot figure out any other way to gain access to the account. Is all lost, or is there something else I can try?
