How to regenerate secret key
The secret key is like a secondary password shared between the authenticator app on your device and your Knowledge Hub account. If you have multiple devices, they must all share the same secret key.
If you feel that the secret key has been compromised, you should regenerate and save a new secret key.
To do this, log in to your Knowledge Hub account.
Select your name at the top of the page, which will then show you a drop-down menu.
Select the 'Settings' link (or you can select the 'Settings' tab if you are already within your profile).
Select the drop-down arrow in the blue box and select 'Two-factor authentication'.
Click on the link next to the bar code 'Regenerate Secret Key and QR'.
Scan the new barcode or enter the new secret key manually into the authenticator app on your device.
Select 'Verify Code' to verify your generated code.
