Invalid grant for user signup

Hi @shola.agunbiade,

I have an update!

The “Wrong email or password” error description is stating that the issue is coming from either a wrong email or password. (Reference: Invalid_grant error code received instead of documented error codes - #7 by thomas.osborn)

Because of this, I decided to test the Password-realm grant type on my end. In my tests, I could successfully get an access token with the following code:

const axios = require('axios');
const qs = require('qs');
let data = qs.stringify({
  'grant_type': 'http://auth0.com/oauth/grant-type/password-realm',
  'client_id': 'YOUR_CLIENT_ID',
  'client_secret': 'YOUR_CLIENT_SECRET',
  'audience': 'YOUR_AUDIENCE',
  'username': 'YOUR_EMAIL_ADDRESS',
  'password': 'YOUR_PASSWORD',
  'scope': 'openid email profile',
  'realm': 'Username-Password-Authentication' 
});

let config = {
  method: 'post',
  url: 'https://YOUR_DOMAIN.REGION.auth0.com/oauth/token',
  headers: { 
    'Content-Type': 'application/x-www-form-urlencoded'
  },
  data : data
};

axios.request(config)
.then((response) => {
  console.log(JSON.stringify(response.data));
})
.catch((error) => {
  console.log(error);
});

Then, the only way I could reproduce the"Wrong email or password" error is if I passed in an incorrect email address or password.

Given that, could you please make sure you are passing the correct email address and password values in the request?

After doing so, you should be able to make the request using the Password-realm grant.

Please let me know how this goes for you.

Thanks,
Rueben
