@vardaan24 How to enable Time-based One Time Password (TOTP) ? (one-time setup)

Step 1 - Visit smartapi.angelbroking.com/enable-totp
Step 2 - Enter your Angel One client id and trading terminal password
Step 3 - Enter OTP sent to Registered email & mobile. Once OTP is entered, you will see a QR code on the screen.
Step 4 - Open the authenticator app of your choice
Step 5 - Scan the QR code generated from our site on your authenticator app

How to login to SmartAPI using password and TOTP?

Once your authenticator app scans the QR code, it will automatically generate an authentication code (called as TOTP) every 30 seconds. You are required to pass the TOTP code in our existing loginbypassword API endpoint (/rest/auth/angelbroking/user/v1/loginByPassword) by sending a new "totp" parameter via the request body.

The below request parameters illustrates how to send the client code, password and totp to authenticate and get the tokens

{
"clientcode":"your_client_code",
"password":"your_password",
"totp":"enter_the_code_displayed_on_your_authenticator_app"
}
