    Pros: 

    Great idea to bring some peace of mind for security.

    Cons: 

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

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

    Amin Afshar has used this product for one day.

How does it work? Is it sniffing the password and sending to a server? Or is it all client side?

@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. https://security.googleblog.com/...
