So the good news is nobody can go into your radio or receiver and see your bindphrase. The only time it's in plaintext is when you are flashing your receiver or transmitter with new firmware or you are changing it in the webgui. If you are worried about people seeing your bindphrase and sabotaging you then maybe there is a bigger problem where you race than the security of your bind. And besides, there are so many other things people could do to sabotage you when your back is turned how secure the bind is seems like a drop in the bucket. ExpressLRS is arguably the most secure actually. While you can bind elrs traditionally by powercycling the receiver 3 times and puttign the transmitterin bind mode, this does not work if you've set a bindphrase. So where with other manufacturers all you'd have to do to mess with someone's bind is plug in a bind plug or hold a button down, with elrs you'd have to get in the webgui and change the bindphrase or bust out a laptop and reflash the receiver. Not to mention if you are extremely paranoid you can turn off the receiver webgui if you want as part of the flashing options.
