Best I can find is Civic. But they’re not really decentralized and actually not private at all if you read their privacy policy about data retention. I’d say civic is a CEX for Web3 identity. Source: over 1 year ago
You could use Axur Hashcast to see if it returns any results for password breaches from your domain - it shows you the first 10 passwords for free. If you really want to know of all breaches you may need to use multiple services - our MSP ran a password breach scan (not sure what service they used) and I've used Axur, both had unique (and valid) breaches that the other didn't show, as well as some that both detected.
