Choose a Strong Password
To protect your password, it's important to change it periodically and keep it private, since anybody who knows your password may access your account.
To choose a strong password:
Use a different password at Amazon from what you use on other websites. If you need help remembering your password, write it down and keep it in your purse, wallet, or another secure location.
Use at least 8 characters. A minimum of 6 characters is required; a maximum of 128 is allowed.
Avoid passwords that are easy to guess. These include passwords such as "secret," "password," "amazon," or "123456." They also include things like a dictionary word, your name, e-mail address, or other personal information that can easily be obtained.
Tip: Though it's not a requirement, adding numbers or special characters to your password will make it even stronger. For example, the password "rivers2!%" is a much stronger password than "rivers".
Note: Passwords are case sensitive. For instance, "RIVERS2!%" and "rivers2!%" are two different passwords. When choosing a password, remember the capitalisation you use, and make sure that the CAPS LOCK key on your keyboard isn't turned on.
