Sparkassen is discontinuing the S-ID-Check app, requiring customers to migrate to the S-pushTAN system for secure banking authentication. According to local media reports, this transition is necessary to maintain access to online banking services and avoid potential service interruptions as the bank updates its security infrastructure.
The move replaces the S-ID-Check tool, which previously served as a secondary security layer for authorizing online transfers and identity verification. Customers who rely on this specific application must now switch to S-pushTAN to continue managing their accounts digitally.
Why Sparkassen is Replacing S-ID-Check
The retirement of S-ID-Check is part of a broader effort to streamline authentication processes. According to reports from local news outlets, the bank is consolidating its security tools into the S-pushTAN framework. This transition simplifies the user experience by merging identity checks and transaction approvals into a single, more modern application.
S-pushTAN operates by sending a push notification directly to the user’s registered smartphone. Once the user confirms their identity via biometric data or a PIN within the app, the transaction is authorized. This removes the need for the separate S-ID-Check step that some users previously encountered.
How Customers Can Migrate to S-pushTAN
To avoid losing access to online banking, customers must download and activate the S-pushTAN app. According to service updates, the process generally involves:

- Downloading the S-pushTAN app from an official app store.
- Linking the app to the customer’s online banking account.
- Completing the identity verification process as prompted by the bank.
Once the S-pushTAN app is active, the S-ID-Check app becomes redundant and can be removed from the device.
Warning Against Transition-Related Scams
Security analysts and local media reports warn that this transition period creates a window of opportunity for cybercriminals. Phishing attacks often spike during mandatory software migrations when users expect to receive notifications about account updates.
According to security warnings, scammers may send fraudulent emails or text messages that mimic official Sparkassen communications. These messages often claim that the user’s account will be blocked unless they click a link to “update” their app or provide login credentials.
Bank representatives emphasize that official communications will never ask for passwords, PINs, or TANs via email or SMS. Users are advised to download the new application only through official app stores or via links provided within the secure online banking portal.
