Key .by Onlinesecurity and pro.ZA is a free Chrome add-on that provides a unique way to secure your passwords. Instead of using a traditional password, this add-on allows you to generate and use a key. This key is private, invisible, and cannot be copied and pasted, providing an extra layer of security for your online accounts.

Using Key .by is simple. Just head to the login page of the website where you want to enter your password and select "Build key". This will generate a unique key that you can then insert into the password field. The key remains invisible and cannot be copied or pasted, ensuring that it cannot be easily intercepted or stolen.

It's important to note that once you build a key, it cannot be recovered. So if you plan on using the same key for multiple sites, make sure to only use the "Build key" function once. This add-on is a useful tool for those who prioritize security and want an alternative to traditional passwords.
