![]() ![]() While PINs might not seem to offer an advantage over passwords, unlike passwords, Windows Hello PINs can only be used on the device where they are registered. Windows Hello can be used to sign in to Windows 10 and it also provides single sign-on (SSO) to services like Microsoft 365.įor devices that don’t have a built-in biometric device, like a fingerprint scanner, a PIN can be used. To add to the complexity, Microsoft supports three different passwordless technologies in Azure AD and Windows 10:ĭesigned for users that have a designated Windows 10 device, Windows Hello uses the PC itself as the ‘something you have’. Azure AD is the identity management platform used by Microsoft 365, Office 365, and of course Azure. ![]() If you read through Microsoft’s documentation on passwordless sign-in, it refers mainly to Azure Active Directory (Azure AD). Something you are might be a biometric gesture like a fingerprint. ![]() With passwordless sign-in, passwords are replaced by something you have, like a security key, plus something you are or know. Microsoft’s answer to these security problems is passwordless authentication. Multifactor authentication (MFA) helps protect passwords but it has a low adoption rate. Moreover, it’s common that people use the same password across multiple devices and services, increasing the damage if a password compromised. Users also make passwords less secure by choosing passwords that are easy to guess and that can be hacked in dictionary attacks. Around 80 percent of successful attacks originate from compromised passwords. Social engineering techniques, like phishing and malware, make passwords vulnerable. Microsoft has been trying to persuade IT, professionals and consumers, to do away with passwords in recent years. Passwords are a pain and they are also a security risk. ![]()
