Microsoft Passwordless Authentication is a modern authentication method that allows users to access their accounts without having to enter a password. Passwordless authentication provides a more secure and user-friendly way to authenticate users by using alternative authentication methods such as biometric authentication, FIDO2 security keys, or a one-time code sent to a trusted device.
With passwordless authentication, users no longer need to remember complex passwords, which can be a significant security risk if they are easily guessed or reused across multiple accounts. Instead, users can use a device or biometric identifier that is unique to them, such as a fingerprint or facial recognition, to authenticate themselves.
Microsoft supports several passwordless authentication methods, including Windows Hello, Microsoft Authenticator app, and FIDO2 security keys. These methods provide an additional layer of security to protect user accounts against unauthorized access and help to prevent phishing attacks.
Passwordless authentication is supported by various Microsoft services, including Microsoft Azure Active Directory, Microsoft 365, and Microsoft Azure.
