You can store a passkey on your Android device using your phone’s built-in screen lock (such as fingerprint, face recognition, or PIN). This securely saves the passkey to your device and links it to your Google account. Passkeys use public-key cryptography, which is far more secure than traditional passwords. To set up a passkey with an Android device, follow these steps:

Before you begin:

  • Please ensure you are using the latest version of your device’s operating system and web browser.
  • Make sure your Android device is running Android 9 or later.
  • You must be signed into your Google account on the device.
  • You need to have screen lock (PIN, fingerprint, or face recognition) already set up.
  • These instructions assume you are setting up a passkey on the same Android mobile device you are using to sign in to or sign up for myHawaii.

Step 1: Select your MFA option

  • After signing in to your myHawaii account from the myHawaii login page, you may be prompted to register for multi-factor authentication (MFA). If so, please follow the steps below.
  • On the MFA registration screen, select Passkey from the available options.
  • Select Next to continue.

Step 2: Register your passkey

  • From your Android mobile device, you should see a prompt such as “Choose a device for your passkey” with several options like “USB security key,” “Use a different phone or tablet,” or “This device”. Select “This device” to continue.
  • Authenticate using your screen lock method (e.g., fingerprint, face unlock, or PIN).
  • The passkey will be saved to your Google account and available on your other signed-in Android devices.

Step 3: Complete the MFA setup

  • New users will be redirected to their eHawaii.gov profile to complete account setup.
  • You can now use your registered passkey as part of your MFA sign-in process.
  • For added security, you can set up a secondary MFA method in your myHawaii profile.
