This post describes steps you can take to enable or disable Enhanced Phishing Protection to warn users if they reuse passwords used to sign into Windows 11.
Enhanced Phishing Protection in Microsoft Defender SmartScreen helps protect your account passwords against phishing and unsafe usage on sites and apps.
This protection is built into Windows, and it works with Microsoft Defender Endpoint to provide protection on your device and in the cloud. Protection such as Controlled folder access, Real-time protection, Tamper protection and Ransomware protection are included with Microsoft Security.
When you enable Microsoft Defender SmartScreen with enhanced protection, Windows will warn users if they reuse their Microsoft account password on sites and apps and prompt them to change their password.
This also works with any Chromium browser, including Edge. If users type their password into a site deemed malicious by Microsoft Defender SmartScreen, Enhanced Phishing Protection will alert them.
