What is TPIN (CDSL TPIN) and why do I need it?

The CDSL TPIN (Transaction Personal Identification Number) is important because it provides an essential extra layer of security, gives investors greater control over their assets, and prevents unauthorized share sales from a Demat account. It is a six-digit code provided by the Central Depository Services Limited (CDSL) itself, not the broker, ensuring a neutral and secure verification process.
