It is important to have a strong password, and then to keep that password secure. You'll probably know not to use obvious things for your password - so avoid your date of birth, family names and so on. To generate a random, secure password, try Perfect Passwords. You don't need to have 64 characters; 8 or 10 is about right. And then memorise it. Don't write it down or give it to others. Please do not give use the same password as you use for your email.
