I made a device using ESP8266 and I want to sell it
how can I protect my program from stealing using a password

thanks

The compiled image that is produced by the Arduino compiler can be saved back to a file and reflashed to another ESP; an ESP8266 doesn't have a protection fuse (and apart from that: the code is stored in external flash).

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
