How I can check that name is already taken

Hello. Very good service, thank you.

I have a simple question, how I can check if name already taken for create account, but login with this name is possible. (Unity)

This is may code for login, it's standart:

public void Login() {  
 
	var request = new LoginWithCustomIDRequest {  

		CustomId = SystemInfo.deviceUniqueIdentifier,

		CreateAccount = true,  

		InfoRequestParameters = new GetPlayerCombinedInfoRequestParams {  

		GetPlayerProfile = true  }  

	};  

	PlayFabClientAPI.LoginWithCustomID (request, OnSucess, OnErrorMain);  

}

I think that I need to compare device ID with CustomID in account, because if I make without this, no one will be able to login with himself nickname. So, I need to find CustomID by entered nickname from all players and compare with device ID? How I can make this or maybe there is another way?

Sorry for the misunderstanding, if your concern is the repeated Display Names or repeated User Names then you don’t have to worry about it. PlayFab will check if the Name is used when you call API UpdateUserTitleDisplayName, RegisterPlayFabUser or API AddUsernamePassword. If the Name is used, you will get an error message like "Username not available" or “Name not available”.

According to Login basics and best practices, it says that ‘Unless you know exactly why you want LoginWithCustomId in your released title, you should migrate to another login mechanism before you launch.’

You could use Anonymous login mechanisms to get your players into game. But once a player logs into your game, you should prompt them to add a recoverable login method, which makes their account recoverable in the case of device failure or other issues.
