Read full blog postCredential stuffing and password reuse attacks exploit stolen usernames and passwords from data breaches. Attackers use automated tools to test these stolen credentials across multiple sites, capitalizing on users who reuse passwords. Passkeys eliminate these risks by fundamentally changing how authentication works.
Unlike passwords, passkeys generate a unique cryptographic key pair for each website or application. The private key remains securely stored on the user’s device, while the public key is shared with the service. This means that:
Traditional passwords are stored on servers, making them prime targets for data breaches. Passkeys, on the other hand:
Since passkeys are bound to the original website (relying party ID), they prevent phishing attempts that trick users into entering credentials on fake sites. Even if a user unknowingly visits a malicious page, their passkey won’t authenticate the attacker’s site.
Passkeys support secure device-bound storage and cross-device authentication via cloud sync. Unlike passwords, users don’t need to manually type or reuse them across different devices, reducing the risk of compromise.
Passkeys effectively eliminate credential stuffing and password reuse vulnerabilities by ensuring:
By adopting passkeys, organizations can significantly reduce account takeover risks, enhance security, and improve user experience without relying on traditional password-based defenses.
