Protecting your Instagram account from unauthorized access is more important than ever. As digital threats evolve, relying solely on passwords leaves you vulnerable to phishing attacks, credential stuffing, and SIM-swapping fraud. While traditional SMS-based two-factor authentication (2FA) offers some protection, it still hinges on one-time codes that can be intercepted or redirected. Passkey-based 2FA, leveraging device-level biometrics or a secure PIN, provides a far more robust, phishing-resistant layer of security—without the friction of entering codes. In this detailed guide, you will learn how to prepare your devices, activate passkeys in Instagram’s settings, verify your new login flow, manage multiple passkeys across devices, recover access with backup codes, and maintain best practices for ongoing account security.
