What is the Android feature where different passwords open different profiles?

I remember seeing a feature on some Android phones where entering one password/PIN would unlock a normal phone profile, but entering a different password/PIN on the lock screen would open a hidden/private profile with different apps, photos, files, and settings.

It was basically like having two separate phones on the same device, depending on which password was entered.

What is this feature called, and is it available on OnePlus phones (specifically the OnePlus Nord CE 3 Lite)? If not, what's the closest alternative?
