the keyboard in the game at the bottom a little to the right there is a blank button, it is a space bar, you typed "RedBird" i am like you but actually we need to type "Red Bird" correctly, it applies to all the answers after that.
By the way, the password that lost the digits is "Black Turtle", the 4 passwords refer to 4 divine beasts: Vermillion Bird, Azure Dragon, Black Tortoise, White Tiger.
