Can I have multiple LoRa connections at the same frequency, but with a different password?

In "LoRa Mesh Communication without Infrastructure: The Meshtastic Project (ESP32, BLE, GPS)"[1] Andreas Spiess mentions that with a password more than one channel can operate in the same area.

Perhaps this means that I can have multiple LoRa connections operating at the same frequency, but with different passwords.

I may want to explore if this also means that I can have different cryptographic keys and the same frequency.
