Every secret stays on your device, encrypted with hardware-backed keys.

Add your accounts by scanning the QR code your service provides, or by typing in the setup key manually. The app reads QR codes locally on your phone — no image is ever uploaded.

WHY AUTHENTICATOR APP
• Works fully offline. Codes are generated on-device, no internet needed to sign in.
• Hardware-backed encryption. Every account secret is encrypted with AES-256/GCM using a key stored in the Android Keystore. The key never leaves the device.
• Open standards. TOTP (RFC 6238) and HOTP (RFC 4226) — the same algorithms used by industry-standard authenticators, compatible with any site that supports them.
• On-device QR scanning. Camera frames are processed locally and discarded.
• Encrypted backup. Export an AES-GCM encrypted backup file protected by a passphrase you choose, restore it whenever you reinstall the app. There is no cloud account and no server — you stay in control.

ADD ACCOUNTS YOUR WAY
• Scan the QR code on the service's two-factor setup screen.
• Or paste the setup key and customize digits, period, algorithm, or counter as needed.
• Edit names later, swipe to delete, search across your list as it grows.

THE CODES YOU NEED
• 6, 7, and 8-digit codes.
• SHA-1, SHA-256, and SHA-512 algorithms.
• 15, 30, or 60-second periods.
• Counter-based (HOTP) codes for services that require them.
YOUR DATA, YOUR DEVICE

• No account, no signup, no server. The app does not collect any personal information.
• Account secrets are never uploaded.
• Android auto-backup is disabled for this app, so secrets cannot leak through the system backup flow.
• Copied codes are marked sensitive on Android 13+ so they don't appear in the paste preview, and are cleared automatically 30 seconds after you copy them. ## Rankings - #1,256,099 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.CAMERA` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.USE_BIOMETRIC` - `android.permission.USE_FINGERPRINT` - `android.permission.WAKE_LOCK` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.app.authly.authenticator.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` ## Similar extensions and apps - [Authenticator App: 2FA & OTP](https://chrome-stats.com/d/com.vidus6.authenticator) — 56,393 users, 4.66 / 5 - [Authenticator App: 2FA Scanner](https://chrome-stats.com/d/com.authenticator.app.securitycode.scan2fa) — 18,493 users - [Authenticator App](https://chrome-stats.com/d/authentic.password.authenticator.pro) — 276,406 users, 2.11 / 5 - [Authenticator App](https://chrome-stats.com/d/com.authenticator.app.twofa.auth) — 1,896 users - [Authenticator](https://chrome-stats.com/d/com.cwsk.googleauthenticator) — 10 users - [Authenticator - 2FA Codes](https://chrome-stats.com/d/com.hauthenticator.app) — 1,638 users - [Authenticator App - 2FA](https://chrome-stats.com/d/com.twofa.authenticator.app.mfa) — 5,053 users - [Authenticator App 2FA & TOTP](https://chrome-stats.com/d/com.hasancapraz.authenticator) — 691 users - [Authenticator App - 2FA Auth](https://chrome-stats.com/d/com.two.factor.authenticator.app) — 2,749 users - [Authenticator](https://chrome-stats.com/d/com.ddt.aap.authenticator) — 186 users - [Authenticator App: 2FA & MFA](https://chrome-stats.com/d/com.twofactor.authenticator) — 11,592 users, 4.55 / 5 - [Authenticator — 2FA Codes](https://chrome-stats.com/d/com.securevault.authenticator) — 1 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.app.authly.authenticator)
