2FA Live — Authenticator & OTP Code Generator

Secure 2FA / OTP authenticator (TOTP). Scan a QR code or enter a secret. Fully encrypted, no account needed, optional Google sync.

Your 2FA codes, one click away — encrypted, private, and entirely in your control. 2FA Live is a two-factor authentication (TOTP) code generator for Chrome. Add an account in seconds, click a code to copy it, and get on with your day. No sign-up, no ads, no analytics. Your accounts are encrypted with a passphrase only you know and stay on your device — unless you choose to sync them through your own Google profile. ⚡ GET A CODE WITHOUT SAVING ANYTHING Paste a secret key or otpauth:// link into Quick code and a live code appears straight away. Nothing is stored until you tap Save — perfect for the times you just need a code once. ➕ ADD ACCOUNTS YOUR WAY • Scan the QR code on the page you're viewing with one click (only when you ask — the extension never watches your tabs) • Upload or paste a QR code image • Import from Google Authenticator: its "Export accounts" QR code is read in full, even when split across several images, and you pick which accounts to bring over • Paste an otpauth:// link • Type in a secret key manually Duplicate accounts and missing parts of a multi-image export are flagged before anything is imported. 🔐 BUILT TO PROTECT YOUR SECRETS • AES-256-GCM encryption with a key derived from your passphrase (PBKDF2, 210,000 iterations) • The whole vault is encrypted — issuer, label and secret, not just the secret • Auto-lock from 1 minute to 1 hour (or until the browser closes), or lock instantly with one tap • Optional "stay unlocked on this device" for convenience — off by default • No server, no tracking: the developer never sees your accounts or codes ☁️ OPTIONAL SYNC WITH YOUR GOOGLE PROFILE Turn it on in Settings and your vault follows you to every device signed in to the same Chrome profile. Only the encrypted vault is synced — never your passphrase or unlock key — and it's off by default. Switch it off any time to remove the synced copy. (Needs Chrome sync with "Extensions" enabled. Since a copy then lives in your Google account, choose a strong passphrase.) ✨ EVERYDAY CONVENIENCE • Live codes with a countdown ring — click any account to copy its code • Instant search across your accounts • Recognizable logos for popular services • Show an account's QR code to set it up in another authenticator app • SHA-1 / SHA-256 / SHA-512, 6- or 8-digit codes, 30s or 60s periods • Light and dark theme, following your system or set manually 💾 BACKUP & RECOVERY Export an encrypted backup file and import it whenever you need — it merges into your existing accounts without creating duplicates. Please note there is no passphrase recovery: if you forget it, nobody can decrypt your vault, which is exactly what makes the encryption meaningful. Keep a backup, and keep each service's own backup codes somewhere safe too. 2FA Live is an independent, unofficial project and is not affiliated with Google, Google Authenticator, Authy, or Twilio.
