In June 2023, the team at secure productivity software Proton first launched Proton Pass, an end-to-end encrypted password manager that can also securely store things like credit card numbers and more. Today, Proton announced a new feature being added to Proton Pass designed to help detect if your password is part of a data breach and alert its users if this happens.

in a blog post, Proton says the new feature is called Pass Monitor, and as the name suggests, the team scans the dark web to see if your passwords, along with your email addresses and aliases, were part of a security breach. The blog post reads:

We use our own dark web hub datasets, as well as those compiled by Have I Been Pwned (new window) and Constella Intelligence (new window), leaders in digital threat management. We only share personalized email addresses (with your permission) with third parties for dark web monitoring.

If a breach does occur involving your emails or passwords, Proton Pass will send notifications to users so they can make the necessary changes to their passwords and email. The alerts will offer information about which service breached data, what data was involved and when it was discovered. The new feature will also scan your current passwords and alert you if any of them have been reused or are considered weak.

Pass Monitor will also alert you if the services you sign up for have two-factor authentication but haven’t yet activated it. Finally, the new feature will add the company’s Proton Sentinel program. It uses a combination of human analysts and artificial intelligence to try to find and stop any attacks on your accounts.

The new Pass Monitor feature will be available to all Proton Pass users over the next few days. It is available with Proton Pass subscription starting at $4.99 per month.
