Not sure about Apple devices, but for Android there’s FRP (factory reset protection). Basically, if an Android phone which has FRP enabled has at least one Google account signed in, after factory reset, the phone is locked unless it signs into one of the Google accounts previously in use.
I cannot find documents about FRP from Google, but here’s one from Samsung, and I’m pretty sure it’s not limited to Samsung.
I ran into this on my phone when I forgot the pin and tried to factory reset. However I know my Google password so it was quite simple, but I don’t know how thieves get past this.
