## What is Authenticator App?

Your password isn't enough anymore.

Hackers don't need to guess it. They buy it. Every day, millions of login credentials get leaked in data breaches — and a password alone won't stop someone who already has it.

Authenticator App adds a second lock to every account. Even if your password is out there, your accounts stay protected.

Scan a QR code. Done in 30 seconds.


KEY FEATURES

1. Instant Setup with QR Code Scanning
Point your camera at a QR code and your account is protected in seconds. No confusing steps. No clutter.

2. Codes That Refresh Every 30 Seconds
Time-based one-time passwords (TOTP) that expire automatically — so even an intercepted code is useless before it can be used.

3. Works With Thousands of Apps and Services
Gmail, Instagram, X, banking apps, crypto wallets, work tools — if it supports 2FA, Authenticator App works with it.

4. AES-256 Encryption
Your data is protected with the same encryption standard used by banks and governments. On-device. Private.

5. iCloud Backup and Sync
Switch phones without losing access to a single account. Your codes follow you securely across all your Apple devices.

6. Face ID and Passcode Lock
Only you can open the app. No one else sees your codes — even if they're holding your phone.

7. Clean, Ad-Free Experience
No ads. No upsells. No distractions. Just your codes, right when you need them.


BUILT FOR REAL LIFE

Your codes stay ready when it actually matters:

- Logging into a new device for the first time
- Protecting your bank, email, crypto, or work accounts
- Resetting a forgotten password
- Switching phones or traveling abroad

Set up in under 30 seconds. Works with any service that supports TOTP, MFA, or RSA SecurID.

If you've been putting off 2FA, this is the easiest way to start.

One scan. One extra lock. A lot harder to hack.
