About this app

Protect your online identity with the 2FA Authenticator: Secure Key app. As cyber threats increase, securing your accounts has never been more vital. The app adds an extra layer of security by generating one-time codes for your favorite services: time-based codes (TOTP) and counter-based codes (HOTP).

With a clean and simple interface, 2FA Authenticator makes two-step verification fast and reliable. Whether you want to secure your email, social networks or cloud storage, the app generates 6-digit codes on your device, with no internet connection needed.

🛡️ Why Choose 2FA Authenticator?
1. Stronger Account Security: Two-factor authentication (2FA/MFA) means that even if someone learns your password, they cannot sign in without the time-limited code from this app.

2. Easy Setup with a QR Code: Scan the QR code shown by the service you want to secure (such as Google, Facebook, X, Instagram, GitHub, Microsoft and many more), and the app sets up the account at once. You can also type the setup key by hand if your camera is not available.

3. Codes Work Offline: Codes are generated on your device. You do not need an internet connection or mobile network to see them.

4. Encrypted Backup & Restore: Save all your accounts to a backup file on this phone, encrypted with a passphrase that only you know, and restore them in the app when you need to. Keep your passphrase safe: a backup cannot be opened without it.

5. App Lock: Set a PIN to keep others away from your codes. Once a PIN is set, the app asks for it before it shows your codes or the lock settings, and again after you leave the app. Changing or turning off the PIN needs the current PIN.

Time-based (TOTP) and counter-based (HOTP) codes.
