Internet Identity Upgrade 
There is a new Internet Identity upgrade available for voting in the NNS.
This upgrade includes a new feature developed over the last months, which we are excited to announce: Domains Compatibility.
Moreover, this upgrade also includes the analytics setup, as agreed in a previous forum post.
Domains Compatibility
Support For Multiple Domains
The new feature enhances the login experience to support multiple domains seamlessly.
Currently, Internet Identity operates in two domains:
- Identity.ic0.app
- identity.internetcomputer.org
Users have encountered difficulties switching between these domains because their passkeys are tied to the domain they initially registered.
This update ensures that users can log in across all supported domains without creating new credentials in the other domains.
Login
When logging in, II will determine the best way to fetch credentials based on where the user’s passkeys were registered. If a user has multiple devices registered across different domains, the system will try different origins automatically, prompting retries if needed.
Most users will not notice any changes because only a minority has passkeys registered in multiple domains.
New Passkeys
To prevent fragmented passkey registration in the future, new passkeys will always be registered in the same origin as existing ones—whenever the browser supports Related Origin Requests.
Limitations
Firefox, older Safari versions, and third-party password managers extensions do not support Related Origin Requests. Therefore, those users might end up having passkeys in different domains, which could trigger the retries during the login process.
To address potential issues, affected users will be prompted to register their current device on the active domain, ensuring a smoother experience in future logins.
Analytics
The new analytics setup includes integrating Plausible and events to track the Webauthn authentication flow for failures and successes
We will share the public dashboard next week.
