Choose a Strong Password
To protect your password, it's important to change it periodically and keep your password private, since anybody who knows your password may access your account.
To choose a strong password:
Use a different password on Amazon from what you use on other sites. If you need help remembering your password, write it down and place it in your purse, wallet, or another secure location.
Use at least 8 characters. A minimum of 6 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 capitalization you use, and make sure that the CAPS LOCK key on your keyboard is not turned on.
