Take back control of your 2FA workflow

Self-hosted OTP manager for individuals and teams

2FAuth lets you securely store, generate and organize your two-factor authentication codes in a modern web application.

Whether you need to protect personal accounts, manage company access, or secure your family’s online activities, 2FAuth provides a secure and independent alternative to proprietary authenticator apps.

Why 2FAuth?

Most authenticator apps lock your 2FA personal data inside closed ecosystems tied to a single device, account or vendor. It is restrictive, not very agile, and quite time-consuming.

2FAuth takes a different approach to bring you control, privacy and efficiency:

Accessible from anywhere
You own your data
Integrates seamlessly with any authentication workflow
Built for both personal and collaborative use
Allows backup, import and export
Fully customizable

In front of your computer, without your smartphone, dealing with a code request? No problemo, just open 2FAuth in a browser to get a code, and voilà!
