The company said Thursday that users logging in to Microsoft 365 workplace software, Copilot, Xbox and Skype can now use “passkeys” rather than traditional passwords or an authenticator app. That means whatever biometric authentication (such as a thumbprint or face ID) you use to open your phone or computer will be all you need to access your Microsoft account. Passkeys are available on desktop and mobile browsers starting Thursday, with support for mobile apps in the coming weeks, the company said.
