We would like to inform you that the Passkey feature is not available on devices running Android 9 or earlier and iOS 16 or earlier. This restriction is in place because operating systems of those versions do not yet have a decentralized biometric encryption module (WebAuthn protocols) natively integrated with the security standards required by the Passkey feature. To prevent security vulnerabilities in your account, our system automatically restricts access to this feature on older devices.

If you access the Indodax app using a phone running Android 9 or earlier or iOS 16 or earlier, the Passkey menu option will not appear on your account security settings page. The absence of this menu is an automatic response from the Indodax app system to adapt to the technical capabilities of the hardware and software you are using.

If you still want to use the Passkey security feature, we recommend that you take one of the following steps:

• Operating System Update (OS Update): Check your phone’s settings menu and update the operating system to a newer version (at least Android 10 or iOS 17) if your device still supports it.

• Use Standard Security Methods: If your device no longer supports OS updates, there’s no need to worry. Your account remains fully secure and can be accessed using conventional login methods, such as a password combined with Authenticator (2FA) or an SMS/email OTP.

Indodax is committed to maintaining a balance between strict security and your convenience when transacting. If you need further guidance on optimizing your account’s security features, the Indodax Customer Support team is ready to assist you 24/7 via Live Chat on the official app or through our support email.
