About TOTP 2FA Token Generator
The RFC 6238 TOTP (Time-Based One-Time Password) Authenticator generates real-time 6-digit and 8-digit 2FA verification codes from Base32 secrets with live 30-second countdown timers, HMAC-SHA1 / SHA256 support, and zero server logging.
How to Use TOTP 2FA Token Generator
Step 1
Enter your Base32 2FA secret key.
Step 2
Select digit length (default: 6 digits) and algorithm (default: SHA1).
Step 3
Watch the live 2FA code generate with the countdown timer.
Step 4
Click "Copy Code" to paste into your login prompt.
Practical Use Cases for TOTP 2FA Token Generator
Two-Factor Authentication (2FA) Code Verification
Generate real-time login OTP codes for GitHub, Google, AWS, and Cloudflare when setting up or debugging two-factor authentication.
Backend 2FA Implementation & QA Testing
Verify and debug server-side TOTP validation logic by comparing test secret outputs against RFC 6238 standard computations.

Key Terminology & Definitions
TOTP (RFC 6238)
Time-Based One-Time Password algorithm that computes a dynamic verification code using an HMAC hash of the current Unix epoch time and a shared secret key.
Base32 Secret
The standard human-readable encoding used to store and exchange 2FA seed keys without punctuation or confusing characters.
