Credential stuffing is a prevalent cyber attack method where attackers use automated tools to test large volumes of stolen username and password pairs, seeking unauthorized access to user accounts, capitalizing on the common practice of password reuse. Despite having a low success rate of one to three percent, the impact of successful attacks can be severe, prompting legal and financial consequences for businesses under regulations like GDPR. To mitigate these risks, companies are increasingly adopting measures such as multi-factor authentication, bot detection, and monitoring for unusual login attempts. Fingerprint Pro offers a solution that uses unique visitor identifiers to detect suspicious activities and prevent account takeovers by integrating with website login systems without adding friction for legitimate users. This approach involves configuring logic to flag suspicious attempts and implementing additional verification steps like two-factor authentication when necessary, thereby enhancing security while maintaining user experience.
