If you want to grant a third-party provider access to your account information, please follow these steps:

First, install the third-party provider’s app (e.g., Finanzguru) and open it. Select Tomorrow as your bank. You will then be redirected to the Tomorrow app or to your bank account’s login screen. Confirm the connection and log in with your credentials. This is the 1FA (first security factor). We will then redirect you to the Solaris page for the 2FA (second security factor). Give the required consent and enter the OTP code that Solaris sent you via SMS. Solaris will then redirect you back to the third-party application, which can now access your account data. 

The interface accessed by third-party providers was updated in March 2026, so my.solaris—the portal through which third-party connections used to run—has been shut down. If your third-party provider still redirects you to my.solaris, please contact them so they can switch to the new interface.
