TOTP Code Generator (2FA)
Generate TOTP 2FA codes from a Base32 secret — no app needed.
Sobre esta ferramenta
TOTP Code Generator implements RFC 6238 Time-based One-Time Passwords entirely in the browser using the Web Crypto API. Enter the Base32 secret from any 2FA QR code, and the tool shows the current 6-digit code with a live countdown to the next 30-second window, plus the upcoming code so you're never caught off guard. Add multiple accounts — they're stored in localStorage so they persist between visits. An educational panel explains how TOTP works under the hood. This is a backup / recovery tool: always keep your primary 2FA method safe.
