>>861053>>861081this only lets you download the data, not delete it, and it's going to be too much for you to go through.
It takes a while before the download is available so you may not have to worry about the "stranger" downloading that (depending on how many servoces they include)
I wouldn't recommend giving anyone access to your account as they will automatically have access to anything connected to it:
your phone number (if connected)
any passwords saved on your browser
all emails
google photos
drive
any accounts you use google to login
And of course there is no "guest" login because it's your fucking google account, don't do it OP
I wouldn't even give access to my best friend, not out of trust, but for security's sake
