How to reset Samsung Galaxy S9 phone to reassign to new person

[Android Central Question]

I bought phones for my employees. One left, and gave me back her phone. I did a factory reset, thinking it would wipe everything and come back like a new phone. But it now locks me out and still remembers the Google ID and lock screen pattern from the former user. How do I take this back to actual new condition, no lock screen no google account no password. Just a "blank" phone I can set up on the network again.

Factory reset should always be done in settings not recovery, try to get ahold of that employee otherwise the device is useless because Factory Reset protection, no way around it.

Google requires the Google account removed prior to a factory reset or it locks the phone to the previous account when reset. This was done years ago as a way to deter theft, it's referred to as factory reset protection, prevents a stolen phone from being little more than a paper weight but unfortunately leaves employers in situations like you've encountered.
