Protect your online accounts with Authenticator App: 2FA Scanner — a simple, secure way to generate two‑factor authentication (2FA) codes for fast, safer sign-ins and login verification.

This app creates time-based one-time passwords (TOTP) and counter-based codes (HOTP) that refresh automatically, adding an extra layer of protection beyond your password for better account security. Set up new accounts in seconds by scanning a QR code, then get your verification codes anytime — even without an internet connection. Think of it as a lightweight OTP generator you can use anywhere.
