How can I protect my UPI ID?

To protect your UPI ID, use a strong screen lock and create a 4-6 digit UPI PIN that is not easily guessable. Enable biometric authentication if supported. Only download UPI apps from official stores. Never share your UPI PIN or OTP. Be wary of "Collect Requests," as you never need to enter your PIN to receive money. Avoid using public Wi-Fi for transactions. You can also enable app-level security features like those offered by Paytm for extra protection.
