Your Trusted Partner in Sync Passkey implementation.
Cosync AppKey
With PassKeys, the private key never leaves the user’s device and is never shared with the server. This significantly reduces the risk of breaches. Email/password systems store hashed passwords on servers, which can still be targeted in data breaches. PassKeys use biometrics or device authentication (e.g., PIN or fingerprint), making them not only more secure but also more user-friendly compared to entering passwords and additional 2FA codes.
With Cosync AppKey, you can implement Passkey authentication in just a few hours! If maximizing productivity and minimizing overhead are your priorities, Cosync AppKey is the solution you’ve been looking for.
Unlike SMS-based 2FA, which is vulnerable to SIM swapping, interception, and social engineering attacks, PassKeys eliminate these risks entirely. By leveraging secure, phishing-resistant cryptographic authentication, PassKeys provide a more robust and reliable way to protect your users and your application.
The Federal Government’s Login.gov website currently utilizes PassKeys as a second-factor authentication method.
To meet these needs, Cosync is developing an Enterprise version of AppKey. This version will be fully deployable on your servers, providing complete control over your authentication processes. Delivered as a Docker container, it ensures seamless installation and integration into your infrastructure.
