Should a player hide their PlayFab ID from other players? I'm considering implementing a feature in my game that allows adding friends via ID. However, I'm unsure if this should be the PlayFab ID. Would it be better to generate a random ID consisting of letters and numbers, 8 characters in length, and set it as a Generic ID? This would be similar to the Player Tag in Brawl Stars.
After all, the PlayFab ID is a unique player identification method. This ID can be used to request various information about the account. Players often post their ID on twitter, discord, etc. Or does it not matter?
