Please include the following information in your post:

- Which SDK this is regarding:  
react-native-auth0
- SDK Version: 2.13.3
- Platform Version: react-native: “0.67.1”,

Hello people, I am trying to get the mfa\_token from the below method:

```auto
export async function login(email, password) {
  const response = await auth0.auth.passwordRealm({
    username: email,
    password: password,
    realm: 'Username-Password-Authentication',
  });
  return response.accessToken;

```

the problem is that I don’t t get the mfa access token from the catch response, I am only getting this message: [mfa\_required: Multifactor authentication required]. without the mfa access token.

I already granted MFA permission to my app, and I was able to get the MFA token by calling directly the API by postman:

but from the React Native Auth0 SDK using passwordRealm function I am not able.

Does anyone knows what I am doing wrong?

Solution:  
In my Catch error I should concatenate the json string in order to display the mfa token, like in the example below:  
.catch(error =\> console.log(error.json));

before I had it like this:  
.catch(error =\> console.log(error));
