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.
