I successfully installed qiskit, yet am unable to load my account in the Jupyter notebook.

Each time I load my account in Jupyter notebook here is the response I get

RequestsApiError: 401 Client Error: Unauthorized for url: https://auth.quantum-computing.ibm.com/api/users/loginWithToken. LOGIN_FAILED, Error code: LOGIN_FAILED.

What causes this?


This is normally caused by incorrect credentials being used. To fix this you can generate a new API key and update your saved credentials to use this instead.

You can do this by navigating to https://quantum-computing.ibm.com and getting your API key from the My Account section. In a notebook then run IBMQ.save_account('YOUR API KEY', overwrite=True). This will remove any incorrect credentials from your system and then the login should work.

The above answer did not work for me. This worked for me.


By deleting account, you should not be having any active accounts from IBMQ api. check that by getting active accounts


After which generate a new token in your IBMQ experience website, https://quantum-computing.ibm.com/account

And then copy the new token, save that as a variable (I saved it into API_KEY), then save account in IBMQ

IBMQ.save_account(API_KEY, overwrite=True)
