Solarisbank (Bitwala, Kontist, Penta, Tomorrow, formerly Finom) – Notes on Account Integration and Login (as of September 2025)
Solarisbank is a banking-as-a-service platform used by various fintech providers such as Bitwala (nuri), Kontist, Penta, Tomorrow, or formerly Finom as a banking partner. Account access and login processes may vary depending on the partner, but are based on Solarisbank interfaces.
Login notes for Solarisbank-based accounts:
- Initial setup is done via the central Solarisbank portal: https://my.solarisbank.de/portal
- Register with your email address and mobile phone number.
- After registration, you can add all related IBANs/accounts (e.g., Bitwala, Kontist, Penta, Tomorrow) (“Link a new bank account to my.Solarisbank”).
- For each bank connection/pocket (e.g., Bitwala, Penta, Kontist), you may need to link the account individually.
- For access in third-party apps (such as fino), use the login credentials assigned during registration.
- To integrate with third-party services, the account must be enabled once for the respective third-party provider (TPP).
- Note: Finom is no longer a Solarisbank partner; integration is currently not possible.
Security features:
- Solarisbank and its partners use two-factor authentication and secure identification procedures (e.g., VideoIdent).
- Login is always via the official portals or apps of the respective partner bank or via the central Solarisbank portal.
- If you have problems with account opening, lockouts, or identification, contact the support of the respective partner (e.g., support@solarisgroup.com or the respective provider’s support).
Note in case of problems with bank login via fino services:
- Check your login credentials (email and password) for the Solarisbank portal or your respective banking partner.
- Ensure that your two-factor authentication is active and functioning.
- Check whether third-party provider (TPP) access is enabled and valid for your account.
- If the problem persists, have your login credentials, authentication, and TPP access checked by Solarisbank support or your banking partner’s support.
