Oracle Mobile Authenticator is a free Android app that enables you to verify your identity securely using your mobile device as an authentication factor. It provides an additional layer of security when used with username-password authentication. The app generates a one-time passcode for login or can receive login notifications that can be approved with a simple tap.

With Oracle Mobile Authenticator, you can generate a one-time passcode even when your device is offline. The app also supports push notification-based approval, fingerprint or App PIN for app protection, and can be set up via QR code, Config URL, or by entering the key manually.
