Can a paid Minecraft player (me) play with a cracked Minecraft player (my friend) in a aternos server?

Quote from azortics

I want to play with my friend but I am not sure if he can play on a aternos server with cracked on.

What I am saying is do I have to install TLauncher to play with him on my aternos server or can I stay on paid version?
