What is Passwordless Authentication?
Passwordless authentication eliminates the security risks associated with passwords—phishing, credential stuffing, password reuse, and weak passwords. Instead, it relies on possession of a trusted device, biometric verification, or cryptographic keys. Microsoft reports that passwordless methods reduce account compromise risk by 99.9% compared to password-only authentication.
In Microsoft 365
Microsoft 365 supports passwordless authentication through Windows Hello for Business, FIDO2 security keys, Microsoft Authenticator phone sign-in, and certificate-based authentication. Users can register for passwordless methods at aka.ms/mysecurityinfo.
