Website passwords and PINs help identify who you are. Keep your passwords/PINs for all of your accounts and the sites you visit safe at all times. Never write down or share your passwords or PINs with anyone. When selecting a password/PIN, avoid choosing numbers or letters that fall in a sequence or pattern. Also, avoid the obvious choices like your birthdate, address or family names. When selecting a security question, make sure it's something meaningful, so you'll remember it, and personal, so nobody else can figure it out.
