About this app

Sx Auth is your secure two-factor authenticator that stays 100% on your device.

Sx Auth generates the familiar 6-digit one-time codes (TOTP according to RFC 6238) for GitHub, Google, Microsoft, your NAS, and thousands of other services. No cloud, no account, no ads.

Your data stays with you.
Sx Auth has no internet access. No data is collected, analyzed, or transmitted—neither to us nor to third parties. Your secrets are encrypted and stored on your device (AES-256, keys in the Android Keystore).

Features

- Import from Google Authenticator via QR code, even multiple accounts at once

- Categories/Folders: filter with a tap, arrange freely with a long press

- Quick search
- Tapping copies the code; In hide mode, only the tapped code is briefly visible.

- Encrypted backup, password-protected, for transferring to a new device

- App lock via fingerprint or PIN

- Screenshot protection to prevent unauthorized viewing

- German and English, light and dark themes

Simple and fair
No registration, no tracking, no cloud storage. Install and get started.
