Looking to Sell. Do I Need to Secure or Erase?

Just got the "wrong pin" bug on my Pixel C. So I'm just gonna say "F*ck it" and get rid of it.

I know I need to do a factory reset, but do I also need to do the "secure" or "erase" functions from Android Device Manager (https://www.google.com/android/find)? Or will just the factory reset be enough?

Thanks!
