Google Authorisation Code
You can allow the "Yoast SEO" plugin access to your Google Search Console information by entering your Google authorisation code. If you do not know your Google authorisation code, click the "Get Google Authorisation Code" button, and sign in to your Google account.
Once you have your Google authorisation code, enter it into the text field, and click the "Authenticate" button.
Once authenticated, you will be able to select the Profile to use, and view any Crawl Issues reported by Google Webmaster Tools.
