Dapple Security is a passwordless authentication platform that uses biometrics and software-based passkeys to secure employee logins without the need for passwords or hardware security keys. The platform is designed for businesses of all sizes, with a focus on small and mid-sized businesses (SMBs) as well as managed service providers (MSPs/MSSPs). It is built on privacy-by-design principles and uses responsible biometrics, meaning biometric data is processed in a way intended to preserve user privacy. Core capabilities include phishing-resistant multi-factor authentication (MFA), software passkeys as an alternative to hardware tokens, and protection against credential-based attacks. The platform is FIDO Alliance-compliant, indicating adherence to open authentication standards. Dapple Security targets the problem of unauthorized access through compromised credentials, positioning software passkeys as a deployable, cost-accessible alternative to hardware keys. The company was founded by an ex-NSA cryptographic mathematician and operates on a channel-first model, distributing its product through MSP and MSSP partners.
