Find Your Internet Identity number

This page describes how you can find an Internet Identity number that you previously used to sign in to OISY on the same device and browser.

If you forgot your Internet Identity number, you can find it using any of the following methods:

• Review the list of identity numbers you’ve previously used at Legacy URLs, ensuring you use the same device and browser:

  • https://identity.internetcomputer.org.

  • https://identity.ic0.app

  • Important: This will not work once Legacy Identity has been sunsetted, currently slated for January 26th, 2026.

• Look at the number at the beginning of a recovery phrase you may have saved earlier.

💡 Tip: If your Internet Identity still doesn’t show up in the new modal, re-check that you’re using the correct device and browser used during registration.
