In the current era of digital transactions, where financial activities predominantly occur online, safeguarding your investments has become of utmost importance. In order to enhance security, many Demat account providers have implemented a safeguard feature known as TPIN. In this article, we will dig deep into what a Demat account TPIN is, how it works, and why it is essential for investors.

Introduced in June 2020, TPIN is generally a 6-digit password that authorises the broker to deduct specific stocks from your Demat account. It also functions as an alternative to the Demat power of attorney. With the TPIN, you can independently authorise the online sale of shares from your Demat account.

When investors engage in buying or selling securities electronically through their Demat accounts, the TPIN acts as an additional layer of security. Before executing a transaction, account holders are typically required to input their TPIN to verify their identity and ensure that only authorised individuals can initiate trades or make changes to their investment portfolio.

This approach is simpler and offers greater transparency and immediacy since it is done online. The TPIN authorization remains valid for a single day and is limited to the specific stocks for which the TPIN has been provided. The availability of the TPIN facility ensures that shares can only be moved out of your Demat account with your explicit approval. TPIN provides you with safety, security, confidence, and the freedom to maintain complete control over your Demat account regardless of your location or the time of day.

Let’s see how the concept of TPIN came into the picture. Earlier, when you decided to buy or sell shares using your Demat account, broking houses required your authorization for the transactions to proceed. To facilitate this, they typically requested a Power of Attorney (POA) document signed by you. This document permitted them to withdraw securities from your account when you sell them. Unfortunately, this arrangement led to certain issues.

Some broking houses misused the POA by engaging in unauthorized trades. For example, they would deduct securities from unsuspecting investors' accounts even without receiving a request to sell them. Additionally, they would transfer securities without the customer's consent and intimidate them into paying for losses incurred from these trades. The Securities and Exchange Board of India (SEBI) took cognizance of this and introduced the TPIN concept.

When you initiate a transaction, such as buying or selling securities, transferring shares, or pledging securities, the TPIN plays a crucial role in the process. When you initiate a transaction, such as buying or selling securities, transferring shares, or pledging securities, the TPIN comes into play. When you start a transaction, you are required to enter your TPIN along with your regular login credentials. This combination of information ensures that only the authorized account holder, who possesses both the TPIN and the login credentials, can proceed with the transaction. By requiring this additional information, you can prevent unauthorized individuals from accessing sensitive account activities.

Also, by implementing the TPIN system, financial institutions prioritize the security of their customers' accounts. This system is a deterrent to potential fraudulent activities, as unauthorized individuals would need to possess both the login credentials and the TPIN to access an account and perform transactions. In case of any unauthorized attempts, the TPIN requirement serves as an early warning system, notifying you of potential security breaches or suspicious activities.

In addition to protecting against unauthorized access, the TPIN system also provides accountability and traceability for financial transactions. Since each transaction requires the TPIN, there is a digital trail that can be audited and monitored for any suspicious or fraudulent activities. This feature enhances transparency and assists in identifying any potential security breaches or irregularities within the system.

Understanding the importance of the Demat Account TPIN is crucial for investors seeking to strengthen the security of their electronic holdings and transactions.

  1. Enhanced Security

The primary purpose of a TPIN is to safeguard your investments and prevent unauthorised transactions. Even if someone gains access to your Demat account login details, they will still need the TPIN to execute any transactions. This provides an extra security level that helps protect your investments from potential fraud or misuse.

  1. Reduced Risk of Unauthorised Access

By requiring a TPIN for transactional activities, the chances of unauthorised access to your Demat account are significantly minimised. This feature ensures that only the account holder, who possesses the TPIN, can initiate transactions. It is a deterrent to potential hackers and ensures your securities are protected.

  1. Control Over Transactions

The TPIN system empowers investors with better control over their Demat account transactions. You can review and authorise each transaction individually by entering the TPIN, ensuring you have complete oversight of their investment activities. This control helps in detecting and preventing any fraudulent or suspicious activities promptly.

  1. Compliance with Regulatory Guidelines

The implementation of TPIN in Demat accounts is in line with the regulations set forth by regulatory bodies like Securities and Exchange Board of India (SEBI). These guidelines are designed to protect investors' interests and maintain the securities market's integrity.

  1. Convenience with Security

While the TPIN system adds an extra layer of security, it doesn't overly complicate the transaction process. Once you are familiar with the process, entering the TPIN becomes a routine part of your transaction activities. It strikes a balance between security and convenience, ensuring that you can conveniently access and manage your investments while keeping them safe.


The introduction of TPIN has brought significant advantages to the realm of security and convenience for investors. Beyond its primary function of adding an extra layer of security, TPIN has also revolutionised the traditional practice of physical POA documents. With the implementation of TPIN, investors no longer need to go through the difficult process of physically signing POA documents, which requires time and effort.

Instead, TPIN has streamlined the authorisation process, allowing investors conveniently and securely authorise transactions from their Demat accounts without needing physical documentation. This transition from physical POA to TPIN has enhanced security measures and simplified procedures, making it easier for investors to manage their investments efficiently.

While a regular password is used for general account access, a TPIN is specifically required for initiating financial transactions. It adds an extra security layer to ensure that only you, the authorised account holder, can carry out such transactions.

No, it is generally recommended to have a unique TPIN for each financial account you hold. Using the same TPIN across multiple accounts increases the risk of unauthorised access if one account's TPIN is compromised.

If you forget your TPIN, you should follow the account recovery process specified by your financial institution or service provider.

No, you should never share your TPIN with anyone, including friends, family, or even financial institution employees. Keeping your TPIN confidential is essential to maintain the security and integrity of your financial transactions.

If someone unauthorised gains access to your TPIN, they may be able to initiate transactions on your behalf. It is crucial to report any suspicious activities or potential security breaches to your financial institution immediately to mitigate potential risks and protect your account.
