The lock mode was recently introduced to wnr.
For parents who want to control their babies' use of wnr, or for people who think they aren't good at willpower, lock mode is useful.
By using lock mode, all you need to do is to enter a password, then all the settings will be disabled and user cannot exit wnr once wnr is launched.
Currently, there's not a solution for you to retrieve your password. If password is missing, the only thing you can do is to contact me.
