Is iAuthIQ a Google Authenticator alternative?

How does TOTP authentication work?

TOTP (Time-Based One-Time Password) generates a unique 6-digit code every 30 seconds based on a shared secret and the current time. iAuthIQ implements the RFC 6238 TOTP standard — the same standard used by Google Authenticator, Microsoft Authenticator, and most 2FA systems worldwide.

Is iAuthIQ authenticator free?
