Hey! Yes we do have two you!
The formal you is "vous" and is usually used when you're talking to a stranger or like, an elder person as well. That's a form of politeness, That's it!
The informal you is "Tu" and is commonly used when you're speaking to someone you know, friends, family etc
If you use "Tu" to someone you don't know at all, some people could take it as rude!
So yeah, hope it was clear ~
