I want to play a game only with my friends, so, is there anyway to create a game with a password or something?

Thanks!

just invite them to the game and dont put open seats in the game

You mean invite them by email? So, thats the only option? It would be easier if the developers just put an option to create games with password... Why they didnt add that anyway?

If they already have a WL account then you just click create game and choose them from your invite list (if they are not on your invite list then you search their name in the search bar) If they don`t have a WL account then they`ll have to make one first. If you invite them to a game and do not add open seats or other players then it isn`t possible for others to join. No password or something needed, why would you want that if you can just put a limit on the amount of players and then invite your friends so that limit is reached and nobody else can join.

multiplayer>create game>you'll see a list of players-they're you friends, simply add them to the game and take away the open seat. you can also use the search function to find any player by their username ;)
