Importance and benefits of TAN applications for secure online banking


Over the years, there has been a significant improvement in the security of TAN procedures. For secure online banking, TAN (Transaction Authentication Number) applications are important. To safely log into an account or complete a transaction, TANs offer an extra layer of security beyond a password, as they help prevent fraud, provide authentication, ensure compliance, and give users peace of mind. TANs are typically a seven-digit string of numbers used to validate online banking transactions.

What are TAN applications?

Banks and other financial institutions use a Transaction Authentication Number (TAN) application as a security measure for validating online banking transactions. For each transaction, the bank generates a special, one-time code that is provided to the user by SMS or through a mobile application.

Why is TAN important for secure online banking?

TAN (Transaction Authentication Number) is important for secure online banking for the following reasons:

  1. Strong Authentication: TAN serves as an additional layer of authentication beyond usernames and passwords. It provides a unique code for each transaction, ensuring that only authorized users can complete financial activities. This helps prevent unauthorized access to online banking accounts and adds an extra level of security.


  2. Prevention of Fraudulent Activities: TANs function as one-time passwords (OTPs) that are only good for a certain transaction or a finite amount of time. As the attacker would still need a valid TAN to conduct any transaction, the risk of fraudulent activity is reduced even if a user’s login credentials are compromised. It aids in preventing fraudulent activities such as unauthorized fund transfers.

  1. Protection against Phishing: Phishing attacks are a common threat in online banking, where malicious individuals attempt to trick users into revealing their sensitive information. TANs add an extra layer of security by requiring a unique code for each transaction. This makes it more difficult for attackers to impersonate users and carry out fraudulent transactions.

  1. Regulatory Compliance: For secure online banking, many regulatory authorities demand the usage of TAN or comparable authentication techniques. The implementation of strong security measures by financial institutions to safeguard clients’ financial information and transactions is ensured by compliance with these standards. It assures compliance with legal obligations and aids in protecting the interests of clients.

  1. Customer Trust and Security: Using TAN for safe online banking aids in fostering a sense of confidence among customers. Customers are more inclined to use online banking services when they feel confident in the security of their transactions. Increasing client loyalty and satisfaction, it improves the relationship between customers and financial institutions.
