No. Internet Identity is a decentralized service, meaning you control your own upgrade timeline. There is no mandatory deadline. The upgrade will remain available indefinitely.
However, we strongly recommend all Internet Identity users to upgrade before January 26, 2026 at https://id.ai.
After this point, users accessing Internet Identity via legacy URLs (https://identity.ic0.app and https://identity.internetcomputer.org) will see the new product and will be required to go through the upgrade flow before they can continue.
