How does it work? Is it sniffing the password and sending to a server? Or is it all client side?
@school_4_ants skimming through the source code it looks like they check against a firebase database https://password-api-prod.fireba...
@school_4_ants According to Google they use "multiple rounds of hashing, k-anonymity, and private set intersection with blinding" to secure the username/password before sending them to a server.

Seems to work instantly. Not sure if this is a good or bad thing.


Great idea to bring some peace of mind for security.


Does it really need to be an extension? I think a website would have been sufficient.

If it's a Chrome Extension then it comes w/ you... otherwise, it's unlikely you'll visit a website repeatedly to check your passwords.
Great job!! 😊 Great move by Google
