Guide to secure your SmartAPI Account with two factor authentication

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 or PIN
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"
}

Is the new login flow supported via SDKs?

Yes. To support the login authentication flow using TOTP we have updated and released libraries for Python and Java. Same can be referred here -

Python - https://github.com/angel-one/smartapi-python
Totp changes have been deployed in the latest python release 1.3.0
Please use the following command to upgrade to the latest python release
pip install smartapi-python --upgrade

Java - https://github.com/angel-one/smartapi-java

The latest jar version v2.0.0 containing login with totp changes has been released here - https://github.com/angel-one/smartapi-java/tree/main/dist
Sample Java Code - https://github.com/angel-one/smartapi-java/blob/main/src/main/java/com/angelbroking/smartapi/sample/LoginWithTOTPSample.java

GOLANG - https://github.com/angel-one/smartapigo

What is 2FA?

Two-factor authentication (2FA) is a method of authentication using the following two factors:

Knowledge factor i.e. something only the user knows like. password, PIN etc
Possession factor like OTP, authenticator apps etc

Why use it now?

The exchange vide circular ref no. NSE/COMP/52623 (https://www1.nseindia.com/content/circulars/COMP52623.pdf) has now mandated 2FA for login purposes from September 30, 2022

Which authenticator app to use?

Tested and recommended 2FA authentication applications:

Google Authenticator
Microsoft Authenticator

@nikaashpuri
I also faced similar issue. After upgrading pyotp the issue is resolved for me

$pip install --upgrade pyotp

I have suddenly started getting the following error when logging in using username, password, and otp using the API:

File "abc.py", line 327, in test_login_access
    data = angel_obj.generateSession(user_id, password, totp.now())
  File "/home/ubuntu/py37-venv/lib/python3.7/site-packages/smartapi/smartConnect.py", line 239, in generateSession
    id=user['data']['clientcode']
TypeError: 'NoneType' object is not subscriptable

What is going on here?

@webseos Thanks for your simple and effective answer. This works really well.

@Sukhwant280 said in Guide to secure your SmartAPI Account with two factor authentication:

smartApi.generateToken(refreshToken)

Why would you need smartApi.generateToken(refreshToken)?

ravindra.e · Oct 3, 2022, 5:47 PM

@smrtsaravanan Can you please paste your code here?

Oct 3, 2022, 10:17 AM

@admin thanks for update

Hi @patisupa , we have modified the goLang. Please refer here - https://github.com/angel-one/smartapigo

Oct 3, 2022, 5:39 AM

@admin What about golang library it is updated for totp changes.

webseos · Oct 2, 2022, 7:39 PM

@aj_Brk I have used similar code as given below , but got the following exception
Exception : Object of type TOTP is not JSON serializable

but then I solved the problem

But then I added last two lines and problem solved the last two lines given at the end of the following code- qrOtp is the code generated here : https://smartapi.angelbroking.com/enable-totp below the QR Code. So you have to generate your own qrOtp code here in this site. Then Install pyotp using command line "pip install pyotp"

My Code Below ( Last line totp = totp.now() is very important)

from smartapi import SmartConnect #or from smartapi.smartConnect import SmartConnect
import config
import pyotp

client_code = "aaaaaa"
client_pass = "bbbbbb"

apiKey="yyyyyyy"
qrOtp = "xxxxxxxx"
totp = pyotp.TOTP(qrOtp)
totp = totp.now()

smartapiObj =SmartConnect(apiKey)

data = smartapiObj.generateSession(client_code,client_pass,totp)
print(data)

smrtsaravanan · Oct 2, 2022, 7:36 PM

@smrtsaravanan it is working fine now. Ignore it.

I have made a couple of changes. 1st I have declared it like below

obj=SmartConnect(api_key=apikey)
totp = pyotp.TOTP(s='yourkey')
print("pyotp",totp.now())
attempts = 5
while attempts > 0:
attempts = attempts-1
data = obj.generateSession(username, pwd, totp.now())
print(data)
if data['status']:
break
tt.sleep(2)

and entered my new API key.

Hope it helps!

Sukhwant280 · Oct 2, 2022, 7:03 PM

@ravindra-e Thanks for the code.. Its working for me but it fails when I pass this token to next steps i.e.
smartApi.getProfile(refreshToken)
smartApi.generateToken(refreshToken)
Error is: Invalid json response.

My understanding is that he refresh token is valid until 5 AM next day, hence I can use the same refresh Token whenever I want to make API calls.

Please correct me if my understanding is wrong here. Thanks in advance

@admin , @Ashok - Please help.
