Can I use a LiftMaster remote on a Craftsman garage door opener?

Yes, you can use a LiftMaster remote on a Craftsman garage door opener in many cases because Craftsman garage door openers are manufactured by Chamberlain Group, same parent company as LiftMaster and Chamberlain, and share same Security+ technology and frequencies, so remotes are often compatible if Learn button colors match. Craftsman openers use Security+ rolling code, so LiftMaster remote that matches Learn button color frequency will work. For example, if your Craftsman opener has yellow Learn button indicating Security+ 2.0 MyQ tri-band from 2011 onward, you can use LiftMaster remote like 893MAX, 895MAX, 893LM that are Security+ 2.0 compatible. If Craftsman has purple Learn button indicating 315 MHz 2006-2014, use LiftMaster remote compatible with purple like 893LM purple. If Craftsman has red/orange Learn button 390 MHz, use LiftMaster remote for red/orange like 61LM. To program LiftMaster remote to Craftsman opener, press Learn button on Craftsman motor unit, LED lights steady for 30 seconds, then press LiftMaster remote button within 30 seconds until opener lights flash indicating success. Some older Craftsman with DIP switches may not be compatible with newer LiftMaster rolling code remotes, need DIP switch remote. Check Craftsman model number and Learn button color and LiftMaster remote compatibility chart. So yes, LiftMaster remote can work with Craftsman if frequency matches.
