I amtrying to implement passwordless authentication with email+otp method below is the code for signup and for request otp and verify otp and error response.
Signup
const express = require("express");
const router = express.Router();
const dotenv = require("dotenv");
const { ManagementClient } = require("auth0");
const axios = require("axios");
dotenv.config();
// Request data to obtain the access token
const requestData = {
grant_type: "client_credentials",
client_id: clientId,
client_secret: clientSecret,
audience: audience,
};
const getToken = async () => {
try {
const response = await axios.post(tokenUrl, requestData);
const accessToken = response.data;
return accessToken;
} catch (error) {
console.error("Error obtaining access token:", error.message);
throw error;
}
};
router.post("/signup", async (req, res) => {
const { email, password, username } = req.body;
try {
// Obtain the access token
const accessToken = await getToken();
console.log(accessToken);
// Auth0 Management API configuration
const management = new ManagementClient({
domain,
clientId,
clientSecret,
token: accessToken
});
// Create a new user using the Management API
const newUser = await management.createUser({
email,
password,
username,
connection: "Username-Password-Authentication",
app_metadata: {
app_name: "anasuria",
},
});
// Extract the user ID from the createdUser response
const userId = newUser.user_id;
console.log(userId);
res
.status(200)
.json({ message: "User created successfully", user: newUser });
} catch (error) {
console.error("Error during signup:", error.message);
res.status(500).json({ error: error });
}
});
module.exports = router;
Login Request Code
const express = require("express");
const router = express.Router();
const dotenv = require("dotenv");
const { AuthenticationClient, ManagementClient } = require("auth0");
const jwt = require("jsonwebtoken");
const axios = require("axios");
const auth0 = new AuthenticationClient({
domain: domain,
clientId: ClienrtID,
clientSecret: secret,
});
router.post("/magiclogin", async (req, res) => {
const data = {
email: req.body.email, // Replace with the user's email
send: "code",
authParams: {
response_type: "token",
scope: "openid email", // Specify the desired scope
},
};
auth0.passwordless.sendEmail(data, function (err, user) {
if (err) {
console.error("Error sending passwordless email:", err.message);
// Handle the error.
} else {
console.log(
`Passwordless email sent successfully: ${JSON.stringify(user)}`
);
res.send(user);
}
});
});
module.exports = router;
Verify OTP
const express = require("express");
const router = express.Router();
const dotenv = require("dotenv");
const { AuthenticationClient, ManagementClient } = require("auth0");
const jwt = require("jsonwebtoken");
const axios = require("axios");
const auth0 = new AuthenticationClient({
domain: domain,
clientId: ClienrtID,
clientSecret: secret,
});
// Step 3: Magic Link for Login
router.post("/verifyotp", async (req, res) => {
const data = {
Grant_type: "http://auth0.com/oauth/grant-type/passwordless/otp",
username: req.body.email,
otp: req.body.otp,
realm: "email", // Use "email" for OTP sent to email
//scope: "openid profile", // Adjust the scope as needed
};
auth0.passwordless.signIn(data, function (err, response) {
if (err) {
console.error("Error verifying OTP:", err.message);
// Handle the error.
res.send(err);
} else {
console.log("OTP verified successfully.");
res.send(response);
// Assuming OTP verification is successful, exchange the code for an access token
}
});
});
module.exports = router;
