This authentication consists of a new type of user credential that is tied to a device and uses a biometric or PIN.
Windows Hello for Business lets user authenticate to an Active Directory or Azure Active Directory account. Windows Hello addresses the following problems with passwords: - Strong passwords can be difficult to remember, and users often reuse passwords on multiple sites. - Server breaches can expose symmetric network credentials (passwords). - Passwords are subject to [replay attacks](https://go.microsoft.com/fwlink/p/?LinkId=615673). - Users can inadvertently expose their passwords due to [phishing attacks](https://go.microsoft.com/fwlink/p/?LinkId=615674). >[!div class="mx-tdBreakAll"] >| | | | >| :---: | :---: | :---: | >| [![Overview Icon](images/hello_filter.png)](hello-overview.md)
