How can i reset a password for Rslogix500 program

i created password for Rslogix500(ML 1000) program and i forgot how can i get back that?

since you created the password, did you write it down, put it on a file
or some other way to keep up with the password?
if yes, open the file offline and type in your password.
if not, you need to contact your local distributor for help in getting the password reset.

The easiest way is to redo your program from scratch without password, reset cpu and put the new program in it.
Or contact AB and you will have to pay and convince them that you own the plc program rights
