What would be a good password for iphone?

Idk any good iphone security password can you help me? Thank you:)

Type in password as your password always works

The last digits of your social security, you can spell out someones name with digits, you can do your fav #'s. Anything really.

Your mom's maiden name.
Your place of birth.
Relatives birthday.

Zip code!
