Oh, asking for identity confirmation to power off? That's a new one on me, must be a Samsung feature (as I'm running Android 11 and have nothing like that).

I can only suggest looking in your security or power settings. If it's controllable at all one of those would be the logical place to put it, but Samsung do everything their own way so I can't guarantee my definition of logical is the same as theirs (or indeed that there is an option to do this). I'd start with Security settings though (and don't forget to look under "advanced").

 

do not have that on my note 10+ 5G. are you using the stock lock screen?

 

Well it's not on my note 10+..... Must be a S9 thing.....lol

Thanx for posting your solution to your issue.

Edit...... Turns out that I have it under lockdown security......huh? Did not know that was there.
