If you're like me, you've likely established many accounts with online retailers, many of which also store your payment information. How easily can hackers guess your password and control your account? To avoid storing passwords, websites typically store a hashed version in their database. A secure hash algorithm creates a unique representation of your password that cannot be reversed. So when you enter your password, its hashed and compared to the stored hash. If they are the same, then you've entered the correct password. If the stored hash is stolen, the hacker can't reverse it back to a password, but they can try to guess your password. That's why its crucial that online retailers enforce good password creation when accounts are created. That means they should these best practices:
- Require a minimize length
- Mix alphas, digits, and upper/lower case
- Disallow commonly used passwords like '123456'
- Use email to verify accounts
- Limit the number of invalid attempts
Of course enforcement is all over the board. Dashlane, the provider of secure password management software, recently graded the top 100 e-commerce sites on their password management policies. You can see the results in the infographic below:
The details of the study are available here. According to the study, Northern Tool and 1-800-Flowers allow one character passwords. Thankfully, most of the retailers send an account confirmation email, and none of those send the password in cleartext. Want to use 'password' as your password? No problem at LL Bean, Gap, and Costco. When you change your password, Blue Nile, Karmaloop, and MLB will email your password in cleartext. And and Amazon, Aeropostale, and Shoebuy don't limit your password guesses.
As an industry, we can do better than this.
