***Do not clear your browser history or website data after setting up your Internet Identity & NNS. We strongly advise users to set up multiple devices.***
The workflow for adding a device can vary depending on what devices you’ve already added to your identity. For example, if you first authorized your computer to create your identity anchor, and you’d like to add your phone as a second authentication method, you must be able to authenticate your phone on the authorized computer. You must always be able to authorize the device you want to add by using a device that is already authorized.
If you are registering a new device, such as a new security key, or a new browser profile using a computer or phone that has already been registered, you can do this easily and directly from within Internet Identity Management.
Other workflows can be more complex, for example, adding your phone as an authentication device using your authenticated computer.
To register your phone as an additional authentication method using the phone’s unlock methods:
Open the Internet Identity web page in your phone’s browser.
Click Already registered but using a new device?
Enter your identity anchor and click Continue.
Click GET STARTED.
Select Use this device with screen lock.
You will be asked to unlock the device.
Authorize your phone.
After you’ve unlocked your phone, you will be provided with a URL and a QR code. You must use the URL or QR code in a browser in the computer that has already been authorized. For example, you can copy the URL and email it to yourself, then paste it into a browser on the computer.
Enter your identity anchor and click Login.
Link your phone to your identity.If you’re sure that the link you pasted in the browser came from you, click Yes, link new device.
Give the device profile a name and click Link Device.
Your phone will be redirected to the login page, and you can now use it with your identity anchor to log in.
