If you haven’t already signed in or created a NETGEAR account, you can easily do this when you first open the Orbi app. We recommend using the latest version from the Apple App Store or Google Play Store. Once signed in to your NETGEAR account, you’ll be able to input your router’s admin credentials to update your router or make any changes your settings. If you haven’t changed your admin credentials before, the default password is password and the username is admin.
Your NETGEAR account is different from your admin credentials and is used for all of your NETGEAR products to receive important security improvements, activate your warranty, and much more. See here for more: What are the benefits of having a NETGEAR account
You can also access your Orbi network by typing orbilogin.net into your browser when locally connected to your Orbi network.
