Password Monitor feature in the new Microsoft Edge browser checks passwords saved to the browser against a large database of known breaches on the cloud and alerts you on the password manager page if it finds a compromised password.
Firefox uses Firefox Monitor service powered by HaveIBeenPwned to alert users when their passwords are breached.
Firefox users can check their online accounts compromised or get future breach alerts by entering their email address on the monitor.firefox.com page. Firefox also previously showed notifications to users when they visited breached sites in the browser.
Google Chrome has Password Leak Detection feature built-in. Chrome allows users to perform a manual scan for breached passwords from chrome://settings/passwords page. This requires you to sign in to your Google account in Chrome browser.
Now Microsoft Edge has joined with Firefox and Google Chrome by offering Password Monitor feature. You can now enable the feature in Edge Dev and Canary versions.
Enable Password Monitor in new Microsoft Edge
1. Launch Microsoft Edge browser
2. Click on the ellipsis icon and select Settings
3. Visit Profiles > Passwords and Enable “Show alerts when passwords are found in an online leak”
From now on, whenever Edge finds your passwords are leaked, it alerts you via notification in the Edge menu and on the edge://settings/passwords page, clicking the alert message takes you to Password Monitor page (edge://settings/passwords/PasswordMonitor) to take action.
Edge lets you go to the website and change your password or ignore the warning.
Ignored leaked passwords will be shown at the bottom on the Password Manager page.
