Secure TOTP Authenticator for Firefox Users

TOTP is a free JavaScript-based authenticator extension designed for the Firefox browser, providing a secure method for generating Time-based One-Time Passwords (TOTP). Functioning similarly to Google's Authenticator and other TOTP applications, it utilizes the browser's crypto API to ensure the secure generation of codes without communicating with external servers. This guarantees that all authentication processes remain private and local to the user's environment.

The extension stores TOTP keys using the browser's password manager, which enhances security by preventing unauthorized access from potentially compromised websites. It operates exclusively within its own unique URL space, thereby mitigating risks associated with autofill mechanisms. Although there is a noted limitation for Linux/X11 users regarding the copy-paste functionality, TOTP remains a reliable and user-friendly option for those seeking enhanced security in their online activities.
