How can I link Aadhaar card with NPS account?

You will have to log in to the NPS account. There you will be getting the section of updating the details where you will have to click the update address or Aadhar details option. Now you will have to provide Aadhaar number two times and then click on the button of generating OTP. After that, you will have to click on the proceed button to provide consent to the NSDL e-Gov to initiate the process of linking. The phone number which is registered with your Aadhar card will be getting an OTP. After providing the OTP, you can continue.
