1.3. How the browser extension detects login passwords¶
Whenever a web page is loaded in a browser, the KeyReel extension automatically analyzes the page for a login or registration form using comprehensive heuristic algorithms.
The Password Vault authorizes the request and responds with the credentials for this site only. Then the extension inserts the login and password into the corresponding form fields. If there are multiple credentials available for a site, the user is prompted to choose the right credentials from a popup list on a computer.
