The bird does not like being handled, it is biting you so that you will let go. Wear a leather glove when you handle the bird and do it often, he will get more used to being handled and get no satisfaction from biting you as it will not hurt and make you put him down. Or get a dog.
Keep your hands away from it's beak.
I have one and if you keep whistling to it and stroking it if it lets you then eventually it'll trust you and stop biting. But it depends on the cockatiel itself, so sorry if these dont work for you.
You don't they just keep biting and biting and biting.
Try using a nail polish, this will stop you, or using creams that leave a bad taste in your mouth. Learn more at stopnailbiting.net
My cockatiel bites itself on the back whenever it has an itch. This may be the cause.
The best way to train a cockatiel, is always to have it from a young age so it grows up with you. When it bites you, or nips at you, do not talk to it, just put it back in it's cage. It will soon learn that if it bites, it get's put back in the cage.
