Features & Capabilities

KeyGuard Authenticator App by KeyGuard is a free, comprehensive solution for managing two-factor (2FA) and multi-factor (MFA) authentication on iPhone and iPad. It generates time-based OTP/TOTP codes for accounts—from Google and Facebook to thousands of services—while offering offline access, encrypted backups, and secure cross-device sync to keep you protected anywhere.

In addition to 2FA, it doubles as a password manager with autofill, optional built-in VPN, and strong biometric or PIN protection. End-to-end encryption ensures your data remains private, whether stored locally or in the cloud. Start by adding the accounts you want to secure, enable encrypted backups and 2FA, and enjoy a unified security solution for your online life.

Bought a new iPhone 17 and the app didn’t transfer over previously included sites. Your app continues to make it difficult.
