	/// <see cref="LoginCredentialType.ExchangeCode" /> - Token is the exchange code.
	/// <see cref="LoginCredentialType.PersistentAuth" /> - If targeting console platforms, Token is the long lived refresh token. Otherwise N/A.
	/// <see cref="LoginCredentialType.DeviceCode" /> - N/A.
	/// <see cref="LoginCredentialType.Developer" /> - ID is the host (e.g. localhost:6547), and Token is the credential name registered in the EOS Developer Authentication Tool.
	/// <see cref="LoginCredentialType.RefreshToken" /> - Token is the refresh token.
	/// <see cref="LoginCredentialType.AccountPortal" /> - SystemAuthCredentialsOptions may be required if targeting mobile platforms. Otherwise N/A.
