Bypass locked phone after reset

[S_1]

I done a software repair on my sisters Xperia xz premium through the Xperia companion computer application and it said you must know the original google account email and password on the phone, my sister said she knew it so I proceeded. She does not know it, she has tried multiple email addresses that were once synced to her phone but none of them work. After trying to sign in, it comes up with a message that says something about a recent password change and to try again in 72 hours but nothing is working.

Is there a way to bypass this? Can Sony bypass it?

if she recently change the password for the google account, it wont be able to log in the device for 72 hours.

I dont know if this works but its worth a try.. http://www.techoxygen.com/bypass-google-account-frp-sony-xperia-z5-x-xa-android-6-0-1/

I know that's what I said, to make it clearer no emails work after 72 hrs, trying one every 72 hrs. Thank you for your reply though
