01 / THE PROCESS
How it works
01
Enter your key
Paste a Base32 secret or an otpauth:// setup link from the service you use.
02
Generate instantly
The TOTP code is calculated on this device with your browser’s Web Crypto API.
03
Copy and verify
Copy the one-time code to sign in. The code refreshes automatically.
02 / CAPABILITIES
Small footprint. Everything essential.
Supports RFC 6238 TOTP, 6- and 8-digit codes, SHA-1/256/512, custom time periods from otpauth links, clipboard paste and QR scanning on supported browsers. No external JavaScript or CSS dependencies.
03 / PRIVACY
Your key stays yours.
Nothing is sent to a server or saved in local storage. Closing or reloading the page clears the current secret. Use HTTPS (or localhost) and keep your device clock accurate.
