Santander – Notes on Account Integration and Login (as of September 2025)

Santander online banking enables you to centrally manage your accounts, cards, securities accounts, and financial products – around the clock, from PC, tablet, or smartphone. You can make transfers, manage standing orders, use your mailbox, and handle many services online.

Login notes for Santander online banking:

• Access is via your username (often the 10-digit participant number/identification ID, or an individually assigned username) and your personal password.
• To authorize transactions and sensitive actions, a TAN procedure is required (e.g., SantanderSign app or mobileTAN/SMS-TAN).
• If you have problems with your login credentials or password, you can reset them using the “Forgot username/password?” function on the login page.
• After several failed attempts, access will be blocked for security reasons. Unblocking is possible via support.
• The login credentials are valid for both online banking and the Santander banking app.

TAN procedures:

• SantanderSign: Authorize transactions via the app on your smartphone (push TAN, biometric authentication possible).
• mobileTAN/SMS-TAN: TAN is sent via SMS to your registered mobile phone (gradually being replaced by SantanderSign).

Note in case of problems with bank login via fino services:

• Check your login credentials (username/participant number and password) for Santander online banking.
• Ensure that your TAN procedure (SantanderSign or mobileTAN/SMS-TAN) is active and functioning.
• Check whether third-party provider access is enabled and valid at your bank.
• If the problem persists, have your login credentials, TAN procedure, and permissions checked by Santander Bank.
