Security & privacy

Trust the architecture, not a slogan.

TOTP generation happens with Web Crypto in your browser. This build has no API for receiving secrets, no analytics integration, and no advertising scripts.

01Client-side codes

Your TOTP secret is used locally to generate the current code.

02Encrypted local vault

Saved accounts are stored as AES-GCM encrypted data in IndexedDB.

03Portable backups

Export the encrypted vault without exposing plaintext account secrets.

04No forced account

Quick generation and the local vault work without signing up.

Important: A compromised browser, malicious extension, or infected device can still expose data shown or decrypted on that device. Keep recovery codes for important services.
