Disable SmartScreen Enhanced Phishing Protection "password reuse" notifications

Overview​

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script disables the Warn me about password reuse feature in Defender SmartScreen's Enhanced Phishing Protection.

The script prevents SmartScreen from warning users when they reuse their work or school password across different services 1 2. The feature aims to encourage users to change reused passwords 1.

This feature is off by default 1. By explicitly disabling it, the script ensures it remains inactive persistently.

This script improves privacy by reducing the password-related data shared with Microsoft. It may also improve system performance by eliminating the background processes that check for password reuse. This feature may occasionally misidentify password reuse 2, potentially causing user inconvenience.

However, disabling this feature may reduce security. The Center for Internet Security (CIS) recommends keeping it enabled for stronger security 2. When active, this feature alerts users if they try to use a password that has been exposed in a known data breach 2. This can help reduce the risk of unauthorized access to online accounts and encourage the use of strong, unique passwords 2.

Caution

Disabling this feature means you won't receive warnings about potentially compromised passwords, which may increase your risk of using unsafe passwords.

Technical Details​

This script sets the NotifyPasswordReuse 1 3 4 policy to disabled state. This setting applies only to Microsoft accounts used for Windows or browser login 2. It is only supported on Microsoft Windows 11 and later versions 1 2. It does not affect on-premises domain-joined accounts 2.

This script uses Batch (batchfile) scripting language.

Not Advised

This script should only be used by advanced users. This script is not recommended for daily use as it breaks important functionality. Do not run it without having backups and system snapshots.
