2fa Snap

TOTP code generator with encryption and cross-device sync

Never lose your 2FA codes. 2fa Snap generates time-based one-time password (TOTP) codes right in your browser toolbar and keeps them encrypted and synced across every device where you sign in to Chrome. No phone number, no new account — just the Chrome you already use.Click any code to copy it. The countdown shows how long it stays valid, and the next-code preview means you never paste a code that's about to expire. 🔐 SECURE BY DESIGN • Accounts are stored in an AES-256-GCM encrypted vault. • The master key is generated randomly on your device — not derived from a password. • Optional device password lock: the vault locks and asks for it again after inactivity. • Windows Hello biometric unlock on Windows (fingerprint or face). • No analytics, no ads, no third-party servers: everything runs locally in your browser. 🔄 SYNC ACROSS YOUR CHROME DEVICES Sign in to Chrome and your encrypted vault follows you: install 2fa Snap on a new PC and your accounts are already there. Lose a laptop? Your codes are still in your Google account — just sign in elsewhere. ✨ FEATURES • Live TOTP codes with countdown and next-code preview • One-click copy — codes shown in easy-to-read pairs • Add, edit and delete accounts • Import: restore from a .txt backup (one otpauth:// link per line) on a dedicated, localized import page • Export: one-click backup of all accounts in standard otpauth:// format • Search with smart filtering: accounts matching the current site appear first • Dark, light and system themes • Works offline — codes are generated locally 🌍 13 LANGUAGES English · Español · Français · Deutsch · Italiano · Português · Русский · 中文 · 日本語 · العربية · বাংলা · हिन्दी · اردو Right-to-left interface support for Arabic and Urdu. 🔒 PRIVACY FIRST No tracking, no ads, no data collection.
