Security News > 2020 > June > Microsoft Edge browser: This new password monitor helps keep your data safe
The new Edge browser will soon warn you if one of your passwords shows up in a data breach - a feature based on an Azure service that enterprises can already use to protect user passwords.
Browser extensions like PassProtect warn you if the password you're using to log into a site is known to have been compromised and listed in a data breach, often based on the excellent Have I Been Pwned service.
Office 365, Xbox Live and Outlook are among the first services that attackers try out leaked usernames and passwords on, because so many people reuse the same password on different sites; Microsoft calls this a 'data breach replay attack' and it detected 4.6 billion attempts to use passwords lost in data breaches to log into Microsoft services in just one month.
If a password for a different site that you've saved in Edge is being used to try and log into one of the Microsoft services you use, Password Monitor can alert you even if security researchers don't already have a dump of the passwords from a data breach.
The identity protection feature in AAD Password Protection uses the same leaked credential information that Edge Password Monitor relies on, as well as looking at patterns in logins.
