Resetting Samsung A13 without PIN & reset PIN

I have a Samsung A13 phone that has been used, but have no PIN code. The phone is turned on, but locked. To reset the phone I need to shut it down, but to shut it down I need the PIN. The battery is at 100%. I want to fix this before tomorrow. (I could turn on the flashlight, so I'm doing that to drain the battery.) This unlockjournal about the A13 mentions that I repeat entering the PIN to get alternative options to unlock the phone. The only thing that happens is that I get a 30 second time out. --- **Update** As @Robert suggested, I could restart the phone after holding Power + Volume Up + Volume Down for about half a minute. Then I could restart in Boot menu while holding Power + Volume Up. Then I did a factory reset and rebooted. Guess what! The PIN is still needed, so this is not a reset to factory settings. Wiping the cache partition didn't make a difference. Samsung knows the phone and expects an ID of some kind. It offers the option to login using a previously used Google account, but what if that is not possible? **Question** How do I reset the PIN?
