I bought an renew iPhone 8 for my son. When he turned on the phone, asking to set a passcode, he use his old passcode and now the passcode lock the screen, being unable to unlock it.
iPhone 12, iOS 16
Click on the link for instructions on how to reset your passcode without a computer if you have iOS 15.2 or higher.
If you see an iPhone or iPad unavailable message or Security Lockout screen - Apple Support
Otherwise, you can take his phone to an Apple store and ask to use one of their computers to reset it. Or ask a friend or relative who has a computer if you can use theirs.

If the phone was reset correctly by the store who sold you the phone, the iPhone 8 would have powered on to the "hello" screen. You would not be asked to enter a passcode at this time.
If the phone did not display "hello", the phone was not reset correctly by the store.
Return the phone and make sure that the replacement powers on to the screen that you see above.
Did he type in the passcode correctly? Or is the iPhone locked asking the passcode of the previous owner? In this case you need to contact the seller and ask to delete the iPhone from his account
