It is developed in a very nice way... https://protonmail.uservoice.com/forums/953584-proton-pass/suggestions/46854529-proton-pass-monitor-dark-web-scanning-password-h

so this can be closed, but i cannot do it.

It's now available in Proton Sentinel Program. You can close this now

Great feature request, would be very valuable to know that your « secret and unique » email address has been breached so that you can react accordingly

that would be nice!

@Joe Suarez

This is a pretty standard feature in all feature rich password managers (1password, keeper, bit warden, lastpass, etc).

As a security engineer who closely works with threat intel, I would really like this feature to be implemented rather than a basic and very limited hibp check.

I know it's a lot of work, but I think we, the users, would really appreciate seeing proton have our backs proactively in keeping our accounts safe...even if it were a paid feature

While ProtonMail doesn't currently offer darknet scans directly, they are actively exploring ways to integrate such features into their security suite. For general breach awareness, you can use the free service "HIBP", which checks your email address against a massive database of known breaches. You can find it here: https://haveibeenpwned.com/.

For more comprehensive monitoring, consider services like Abine's DeleteMe or Experian's IdentityWorks. These services often cover dark web scans and additional privacy protection features. Additionally, you can find a comprehensive list of B2B data providers offering dark web monitoring and other security services here: https://www.globaldatabase.com/top-10-b2b-data-providers-in-2024

Remember, even with the best security measures, practicing good online hygiene like strong passwords and being cautious about what information you share online is essential for protecting your privacy and security.
