Security code is set in Splashtop Streamer's Security tab

When trying to remote into a workstation with Splashtop we get a request to enter security code.

Security code is set in Splashtop Streamer’s Security tab.

This typically means there is a full version of Splashtop on that machine, and that end of things has a code set for connection. The RMM version and the full version can coexist, but if the owner of the full version does things like add a connection code, you’d need to contend with that.
