MSN Explorer: About passwords
A password is a secret combination of letters and numbers that restricts access to an account.
A strong, secret password is an important part of online safety. Use these guidelines to help create your password:
Choose a password that's at least six characters long. Your password can contain any combination of numbers and letters, but it can't include spaces or symbols.
Use a random combination of letters and numbers. Passwords are case sensitive.
Never use a password that's easy to guess, such as your birth date or child's name.
Don't include your e-mail address, your first name, or your last name in your password.
Never write your password on paper. Instead, use a password that's easy for you to remember.
Never send your password by e-mail or in an instant message.
Change your password every few months.
