Understanding How Time-Based Codes Work The technology behind these security tools relies on the HMAC-based One-Time Password (HOTP) algorithm, specifically the Time-based variant (TOTP). The app then uses this key, combined with the current time, to generate a six or eight-digit code that refreshes every 30 seconds, ensuring that each login attempt requires a fresh, single-use credential.
