Individuals who want a free, secure, privacy-focused two-factor authentication app to protect online accounts with time-based login codes without tracking, ads, or centralized accounts

About 2FAS Auth

2FAS is a two-factor authentication and password management platform centered on its open-source 2FAS Authenticator app, which helps users add a strong second layer of login security to online accounts by generating time-based and event-based one-time codes that refresh frequently to defend against unauthorized access, making it easier to secure email, social, financial, and other services that support 2FA. It is designed to be simple, private, and secure, it works offline, does not store passwords or usage metadata, and doesn’t require users to create an account, offering anonymous use while still syncing codes across multiple mobile devices with encrypted backup options, biometric or PIN protection, and support for importing and exporting authentication seeds so you retain control of your data and can migrate between devices or apps.
