To change the secondary bank account, follow these steps:

1. Log in to console.zerodha.com.
2. Click on the Account.
3. Click on Bank.
4. Click on Modify bank account icon.
5. Enter the new account number and IFSC, and accept the terms and conditions.
6. Select to receive the OTP via e-mail or mobile and click on Send OTP.
   
7. Enter the OTP and click on Verify.

A test transfer is initiated to the new secondary bank account for verification. If this verification fails, or if a joint bank account is being linked and the Zerodha account holder is not the first holder, create a ticket with any one of the following bank proofs:

• A self-attested scanned copy of a personalised cancelled cheque with the name printed on the cheque leaf.
• A self-attested copy of the bank statement with the name, IFSC and MICR numbers clearly visible.
• A self-attested copy of the bank passbook with the name, IFSC and MICR numbers clearly visible.

The request is processed within 48 working hours, and a confirmation email is sent. There are no charges to change the secondary bank account.
