Per Rembrand’s Creator Terms, Rembrand requires creators to connect and verify their Instagram account with Rembrand. This ensures Rembrand can attribute a creator’s video views with the correct video and channel so that the creator can be paid out in a timely and accurate manner.
Steps to verify your Instagram account:
Log in to app.rembrand.com, navigate to “Account Setup” within the left side rail, and click “Verify” next to Instagram within the “Verify Your Social Accounts” section.
Log into your Facebook account. Note that only a professional or business Instagram account can be used. We are unable to verify personal accounts. Additionally, the business Instagram account must be linked to a Facebook page.
After you've entered your login credentials follow the instructions to approve your login on a different device.
Once you have approved, return to the "Account Setup" page on app.rembrand.com and click "Verify" next to Instagram. Reenter your Facebook password, then click "Reconnect".
You will be returned back to app.rembrand.com and will see that your YouTube account is now verified.
