The Best Ways to Prevent Credential Stuffing

Best ways to prevent credential stuffing stuffing attacks are not only common, but cause businesses billions in losses. Consumers are also affected by hackers using their usernames and passwords to login to accounts and steal personal information. Fortunately, companies can prevent these attacks from happening in the first place.

The best way to prevent a credential stuffing attack is to require strong passwords that are not reused across multiple sites or apps, and to use a secure password manager. Additionally, customers should be trained on how to create a stronger password and encouraged to reset their passwords after a data breach.

For e-commerce websites, the most important method for stopping a credential stuffing attack is to implement a multi-step login process. This will add time and complexity to the process, slowing down attackers’ bots. However, be aware that this may adversely affect the user experience for people with accessibility needs such as screen readers.

Besides requiring strong passwords, it’s a good idea to block users from reusing their account ID (usually an email address) or usernames across different services. Additionally, implementing anti-bot technologies like MatchKey from Arkose Labs can help as it imposes dynamic challenges tailored to each login attempt, making it difficult for bots to solve.

Lastly, it’s important to monitor the source of login attempts and identify unusual traffic. This can be done by reviewing the origin of an IP address, limiting traffic from Autonomous System Numbers, or blocking browsers that are known to be used by hackers.
