Trying to link square, but it will not accept our username and password

Trying to link square, but it will not accept our username and password as correct. I think this is because we now require double verification with Square. Is there a work around?

We are sorry that we are not able to find any accounts registered with your email address to check the forms and the issue that you are experiencing. Could you let us know the form ID/URL that you are having the issue with connecting to Square and a screenshot of the error so that we can guide you in the right direction.

Thanks!
