I'm working with nrf24 and an ATtiny 85 MCU using NRFlite library to make rc with search and pair feature, that when u activate the search button the nrf24 starts looking for the Rx module and pair with it without presetting the ID or channel,simply like a bluetooth headset.
the idea here is when two transceivers are connected it must be immune to interference from other similar modules nearby working on same channel.
should i use a randomly generated password from transmitter and saved by receiver and every operation is checked by this password or there is any better ideas?
NRFs don't pair.
isn't possible either by code ?
i've tried but its kinda sluggish
NRFs can send and receive in multiple ways,
but there is nothing like pairing in the hardware or standard driver.
Security is not existent in the hardware.
You need encryption if security is an issue.
Immunity to interference is a dream that will not come true.

I suppose you could do it by custom code.
When a button is pressed, the device goes into an initialization mode and selects a fixed channel and a fixed pipe ID. Over this, the devices negotiate a new channel and pipe IDs for future communication. It is not highly secure but could work for your application.
