The Fall of 2FA: Why Google & Instagram Can't Protect You
From Google account takeovers to Instagram session hijacking, the era of 'secure' 2FA is ending. Centralized identity is failing us.
Miguel Treviño•

For a decade, the advice has been simple: "Turn on Two-Factor Authentication (2FA)."
But what happens when 2FA isn't enough?
Recent reports from Kanakaljabir and Sushyant paint a grim picture of centralized security.
The Google Nightmare
One user reported a 10-year-old Google account being hijacked. The attacker didn't just guess the password; they managed to change the recovery phone number, swap the Authenticator app, and reset the Passkeys.
The result? Total lockout. The victim's digital life—emails, photos, contacts—gone in an instant, with no recourse because "Computer says no."
The Instagram Bypass
Similarly, users are reporting Instagram breaches despite active 2FA. Whether through session token hijacking (stealing the "cookie" after you log in) or sophisticated phishing that tricks you into entering the code on a fake site, the 6-digit shield is crumbling.
The Problem is Centralization
These hacks succeed because your identity is a purely digital entry in a centralized database (
user_id: 12345). If a hacker can convince that database to update a row—by stealing a session token or social engineering support—they become you.Zelf: You Are The Key
Zelf takes a radically different approach. We don't hold the keys to your identity—YOU do.
- Non-Custodial: We can't "reset" your account because we never owned it. A hacker can't call Zelf support and pretend to be you, because we have no "master switch."
- ZK Face Proofs: Authenticating with Zelf isn't about sending a code (which can be stolen). It's about proving liveness and ownership cryptographically.
- Unphishable: You can't accidentally "type" your face into a fake website. The Zelf proof is bound to your specific session and device.
Stop relying on 6-digit codes and email resets. Own your identity fundamentally.
