Microsoft Authenticator Lite Debuts on Outlook in Public Preview

Authenticator Lite taps into Microsoft Authenticator to provide passwordless sign-in for the Outlook email client.


Outlook users who want to sign in without using a password are getting a new feature to help stay secure. Known as Authenticator Lite, the tool is debuting now in public preview and allows users to authenticate by leveraging the Authenticator app on their phone.

To do this, users must have a Microsoft Account. Microsoft brought passwordless capabilities to Outlook alongside OneDrive in 2021. It is a part of Microsoft's overall goal to ditch passwords.

Among the password-less decisions the company has made in recent years include password-free login for Azure AD through Microsoft Authenticator. Elsewhere, customers also get password-free Microsoft Account login with FIDO2 compatibility. Then there's , which uses biometric tools to remove the need for a password.

Microsoft launched its Authenticator app back in 2016. The service provides native multi-factor on devices when accessing a Microsoft Account. Since the launch, numerous features have been added, including a phone sign-in ability, fingerprint support, password free login, and until recently it also supported the Watch but Microsoft has now deprecated support.

How Does Authenticator Lite Work?

Authenticator Lite taps directly into the full Microsoft Authenticator and is based on the FIDO2 standard, which enables passwordless authentication across devices and platforms. Users can enroll their Microsoft account for Authenticator Lite by scanning a QR code on the Outlook sign-in page. Once enrolled, they can sign into Outlook by approving a notification on their phone, or by entering a one-time code generated by the app.

Microsoft says the tool brings more efficient ways to access Outlook without compromising security. This is especially true for users who have Outlook across multiple devices or hold multiple Microsoft Accounts.

Authenticator Lite also reduces the risk of phishing, password reuse, and account compromise. Users can still use their password as a backup option if they lose access to their phone or the app.

Tip of the day: The Windows Clipboard history feature provides the functionality across device, space, and time, letting you copy on one computer and paste the text days later on a different PC. All of it is possible via the Windows 10 clipboard manager, which lets you view, delete, pin, and clear clipboard history at will.

In our tutorial we show you how to enable the feature, clear clipboard history, and enable/disable clipboard sync to meet your preferences. You can also create a clear clipboard shortcut for quick removal of stored content.
