how to change atm pin in atm machine

To change your ATM PIN at the ATM machine, insert your debit card and select the 'Change/Reset PIN' option from the menu. You must first enter your existing PIN and then enter the new four-digit PIN you wish to set, confirming it by entering it again. For security verification, an OTP will be sent to your mobile number registered with the bank, which you must enter on the ATM screen to complete the process. If you have forgotten your existing PIN, many ATMs also offer a 'Forgot PIN' feature, where an OTP is used to generate a new PIN immediately.
