If you need to reset your Citibank password without a debit card, you can typically do so online or by contacting customer service. Visit the Citibank website, navigate to the login page, and click on “Forgot User ID/Password.” Follow the instructions to verify your identity using other personal information associated with your account. Alternatively, call Citibank customer service directly for assistance. Be ready to provide details such as your account number, social security number, or other identifying information to confirm your identity securely. Always use official Citibank channels to protect your account from unauthorized access.
