1. Using the /op command
Use the command /op <player> to op a player on your server.
2. Adding OPs via the LEET app
You can also add OPs via the LEET app.
- Click on 'CONFIGURE' or 'SETTINGS'
- Click on Administrators/OPs
- Add the username(s) of the OPs.
NOTE: Adding an OP via the LEET app also allows that player to keep OP (meaning that they won't lose it if the server restarts, if someone uses the /deop command, etc.). The only way to remove OP from these players would be to then remove them from the app (you can use the /deop command if you used the first way).
