To reset your Citibank internet banking password without a debit card, visit the Citibank website and click on the "Forgot Password" link. You will be prompted to enter your User ID and other required details, such as your registered email address or phone number. Once you verify your identity through a one-time password (OTP) sent to your registered contact, follow the instructions to create a new password. If you encounter any issues, contact Citibank customer service for assistance. This method ensures you can regain access to your account even without a debit card.
