If you see a 401 error message in Qiskit Runtime, regenerate your API token

If you see a 401 Client Error when working with the Qiskit Runtime service, please navigate to the IBM Quantum Platform dashboard(opens in a new tab) to regenerate your API token.

Click the refresh icon to the right of the API token field. Click “regenerate token” in the subsequent modal and then copy the token provided. Once generated, you will need to overwrite your existing tokens using the instructions found in documentation.
