## What is TOTP Authenticator?

Make your important accounts safer — and simpler.

This app is a two-factor authentication app dedicated exclusively to TOTP (Time-based One-Time Passwords).
It combines fast, easy everyday authentication with strong privacy by keeping sensitive information protected entirely on your device.

It does not rely on external network communication, and secret keys are securely stored in the Keychain.
From displaying authentication codes to account migration, every aspect is designed with security as the highest priority.
