Zoho Integration: Encountered error

I am met by this message when setting up to Zoho CRM - what does it mean EXCEEDED_MAXIMUM_ALLOWED_AUTHTOKENS?

Hi there,

The error you have given is related to your account in Zoho. It means you have generated a lot of tokens exceeding the Zoho limit. To solve this, please log into your account in https://accounts.zoho.com/ and check your tokens there. You can delete the unwanted tokens in your account.
