Private by default
Your authentication secrets are encrypted on device and never sent to a Nodebin backend.
All your codes,
in one place.
Fast, private 2FA codes for the accounts that matter. No account required.
Security you don’t have to think about.
Open the app, copy the code, and continue. Everything important happens quietly on your device.
Works offline
Generate codes anywhere, even without Wi‑Fi or mobile service.
Easy to organize
Search, categories, and clear countdowns keep the right code close.
Core access stays free
Viewing and copying the codes you own will never require a subscription.
Your secrets stay yours.
Optional backup and sync are end-to-end encrypted before data leaves your device. Use them when you want them; core authentication works without them.
