What is the difference between Real Authenticator and Google Authenticator?

Google Authenticator and Real Authenticator both use TOTP (Time-Based One-Time Password) codes. The critical difference is purpose. Google Authenticator verifies you to a system (website login). Real Authenticator verifies one person to another person over any channel — phone call, text, video, in person. Google Authenticator cannot stop AI voice scams because there is no system login involved in those attacks.

How is Real Authenticator different from Authy?

Authy is a system-authentication app like Google Authenticator — it verifies you to websites and apps. Real Authenticator is a person-authentication app — it verifies people to each other. They solve different problems. Authy protects your accounts from hackers. Real Authenticator protects your conversations from AI impersonation. You need both for complete protection.

Is Real Authenticator free?

Yes. Real Authenticator is free for up to 3 trusted connections. The Family plan ($4.99/month or $34.99/year) supports up to 8 connections. The Pro plan ($9.99/month, $69.99/year, or $149.99 lifetime) supports unlimited connections. All plans include the same core cryptographic verification functionality.

The Key Distinction: System Auth vs. Person Auth

Every tool in this comparison is good at something. The problem is that Google Authenticator, Authy, and SMS 2FA are all system authentication tools — they verify you to a website or app. Real Authenticator is a person authentication tool — it verifies one human to another. These are categorically different problems. Most people only have tools for the first. Almost no one has a tool for the second — until now.

Tool-by-Tool Verdict

Google Authenticator

excellent for what it does

Best-in-class for protecting system logins. Zero capability for stopping AI voice scams. The attack layer is different. Use it for accounts. It won't help when your grandparent gets a voice clone call.

Authy

excellent for what it does

Strong multi-device TOTP with encrypted cloud backup. Same use case as Google Authenticator. Cannot verify person-to-person identity over a phone call. Necessary but insufficient for 2026 threats.

Video calls (FaceTime, Zoom, etc.)

no longer reliable for identity

Real-time deepfake technology has eliminated video calls as a reliable identity verification method. A $25M fraud in Hong Kong in 2024 demonstrated this at scale. Video adds context but is not proof of identity.

Code words

useful backup, not primary defense

A verbal shared secret is better than nothing and requires zero technology. But it can be extracted through social engineering, data breaches, or family member compromise. Use it as a backup layer alongside Real Authenticator.
