I have successfully added my Macbook Pro as the first authorized device, but failed to add a Macbook Air as the second authorized device.
Here’s the details:
- I have done these:
- open identity.ic0.app
- Already registered but using a new device ?
- Enter User Number
- Then it require me: Use your security key with identity.ic0.app, but I don’t have a security key.
- Then I clicked the backward arrow at upper right, and there’s only one option to verify my identity, which is USB security key. And I stuck here.
Need some help to fix this issue.
