What it means
Edge Password Monitor checks saved username-password pairs against known leaked credentials and warns if it finds a match. That is a reason to change the affected service's password promptly. It does not by itself show that an attacker successfully signed in, when the exposure occurred or whether another account reused the same password. An absence of warnings does not establish that every credential is safe.
A real-world example
A banking login saved in Edge is flagged. The owner deletes the browser entry and the warning vanishes, but the old password still works at the bank. The actual risk was not removed because the service credential remained unchanged.
What to do
Open the bank directly, change the password to a unique one, enable its second factor and review its sign-in and transaction history. Update the saved entry afterward. Replace the same old password on any other service where you reused it.
The distinction that matters
A monitor alert is not a malware scan or transaction-dispute result. The account provider's sign-in records and statements are needed to evaluate actual misuse, and a fresh alert may indicate another saved credential. The correct order is to secure the service, then tidy the browser's saved copy—not to hide the alert first.
