How can I share only a part of my Search Console Properties?

It may be the case that you do not wish to link all your properties in your Search Console with with Toolbox. Unfortunately, Google does not provide an option for such a scenario through their API. It’s either all or nothing.

To be able to only share part of your properties you can use the following workaround: first you create a new Google account, for example, and then you can add access to all the properties you would like to have in the Toolbox to this new account. Lastly you connect this new account to the Toolbox and we can request only the properties you want.
