An operator (OP) is someone who has access to commands that are used for managing the server.
If you need to make an OP user in Minecraft, there are two ways to do so.
Method 1 - Game Panel
When your server is running, start managing the instance and open the Console menu:
Then run the command op <nickname>.
Method 2 - In game command
In case you already have OP privileges yourself, you can set any other player as an OP by joining your server and running this command:
/op <nickname>
That's it! Now you know how to set a player as OP 😊
NOTES:
If you see an error “That player does not exist”, log into the server once and run the command again
To remove the user from OP’s list, run command
/deop <nickname>Type
/helpto see the list of available commands
