Description

Local-only TOTP 2FA code generator. Supports Google Authenticator format. Your secrets stay on your device. Privacy first. LocalBox2FA is a lightweight browser‑based TOTP 2‑factor authenticator that generates RFC‑6238‑compliant verification codes entirely locally on your device, letting you get and copy one‑time codes right inside Chrome without needing a separate mobile authenticator app; save and manage your 2FA secret keys, view real‑time 30‑second countdown timers, use dark‑mode UI, and keep all secrets stored locally so they never upload to any server, while premium unlocks export backup and bulk‑delete functions for convenient account management.
