Passport number, DOB, and expiry date based on my own checking.

I've used this app in the past; https://f-droid.org/packages/com.tananaev.passportreader/

I think anyone needing "fake passports" usually gets them from stolen identities (or stealing a passport from someone similar looking) and getting a new one issued. Probably easier in countries that don't require the passport to be sent back for another one to be issued.
