Password requirements

Your password must be 8-24 characters. It can have:
  • Uppercase and lowercase letters
  • Numbers
  • Special characters: + (plus), = (equal), # (hashtag), ? (question mark), * (asterisk), $ (dollar sign), ! (exclamation point), _ (underscore), - (hyphen)
For a more secure password, avoid using personal details that are easy to guess. Also, stay away from common words or obvious series like 123456 or abcdef.
