tutorial Allow players using a crack version.

[zeiko]

Players with cracked Minecraft cannot authenticate themselves to the Mojang authentication system, which is enabled by default on every Minecraft server. You can disable this authentication system by disabling the "online-mode"

- Go to FTP

- Edit server.properties

- Switch online-mode=true by online-mode=false


Starting in 1.19 you also need to make sure that "Enforce Secure Profile" is disabled in the server.properties.
