A new Chromium browser extension was released (alpha) today in the Monero Crypto-Lock github repository.
https://github.com/monero-ecosystem/Monero-Crypto-Lock/tree/master/browser-extensions/Chromium
This Chromium browser extension enables secure, anonymous authentication to web applications without usernames and passwords. This browser extension is free, open-source software.
I'm currently working on documentation and how-to videos for users and developers.
An Opera version of the Monero Authentication browser extension will be released soon.
A short demonstration of an early development version of this browser extension can be found at:
