Help Needed Rename Admin Prefix

Hi Everyone, I need help in renaming my admin to something else. Currently I can access my admin as ‘mysiteurl/admin’ and I want to change it to something else. Can you please help me out? Also is it possible to change that through htaccess file? If yes then how? and If no then why not? Any help will be really appreciated. Thanks.

Just change the associated route(s)?
