About 2faco
A privacy-first security resource — free tools, honest guides, and everything running locally in your browser.
What We Build
2faco was created to provide simple, secure, and privacy-focused security tools directly in your browser. No accounts required. Privacy-first tools, free forever. Every tool — from password generation to JWT decoding — runs entirely client-side.
Alongside the tools, we publish practical guides on two-factor authentication, data breaches, and account security. Our goal is to make good security habits accessible to everyone, not just developers.
Our Principles
Privacy First
Secret keys, passwords, and tokens never leave your device. Everything runs in your browser.
Free Forever
All tools are free with no paywalls. We monetise through affiliate links and display ads — clearly labelled.
Accurate
Our guides are written carefully and updated when platforms change. Corrections are always welcome.
No Bloat
No heavy frameworks, no trackers. Fast-loading pages that work on any connection.
Our Mission
We believe everyone deserves tools that respect their privacy. 2faco generates time-based one-time passwords (TOTP) locally, without storing or transmitting secret keys. The same principle applies to every tool on the site.
Our long-term goal is to build the most trusted, most useful, and most privacy-respecting security resource on the web.
