After you get into the Retail Mode App, you must use a password to successfully disable the retail mode app. Obstensibly, these passwords are private and not meant to be shared to the public. As a result, I cannot say for sure what (if any) publicly available password will work on your specific device.
However, a good number have been leaked and are available. I am copying a reply from @jason79421, who does not seem to be active on these forums any longer, but whose list includes every password I have found and some that I have not found elsewhere:
here are all the passwords for samsung i have. some are specific to where the device came from.
