Whether you need an authenticator app for two-factor authentication, a fast OTP generator, or a secure way to manage your verification codes, 2Step Authenticator gives you the essential tools in one clean and easy-to-use app.

🔐 Secure Two-Factor Authentication

Generate time-based and counter-based one-time passwords (OTP) for your accounts. Use your authenticator codes whenever a website or service asks for a 2-step verification code.

📷 Easy Account Setup

Add your 2FA accounts quickly using:

• Scan QR Code – Scan the setup QR code provided by a website or service.
• Import QR Image – Select a saved QR code from your device gallery.
• Enter Manually – Add your account details and secret key manually.

🔑 TOTP & HOTP Support

2Step Authenticator supports both TOTP (Time-based One-Time Password) and HOTP (HMAC-based One-Time Password) authentication methods.

Your verification codes can be generated locally, allowing authentication to work without requiring an internet connection.

🛡️ Privacy-Focused Security

Your authentication codes are designed to stay protected on your device.

The app includes a Privacy Screen that hides your codes in the Android app switcher and helps prevent screenshots of the authenticator screen.

You can also protect the application with App Lock using your device security options, such as fingerprint, Face ID where supported, or device passcode.

⏱️ Auto-Lock

Use Auto-Lock together with App Lock to help protect your authenticator when you're not actively using it.

💾 Secure Backup & Restore

Keep your authentication accounts safe when moving to another device.

The Backup & Sync section lets you create an encrypted local backup of your tokens. You can also export your tokens as a password-protected backup file and import them when needed.

This makes it easier to restore your authenticator accounts when changing or resetting your phone.

📤 Export & Import Tokens

Move your authenticator data when needed with built-in Export Tokens and Import Tokens functionality.

Create a protected backup file and restore your accounts on another compatible device.

🔎 Find Your Accounts Easily

Use the built-in search feature to quickly find an authentication account.

Organize your tokens with categories such as:

• All
• Social
• Work
• Finance
• Other

This helps keep your 2FA accounts organized as your collection grows.
