Welcome to the world of AWS Cognito, where user authentication and authorization are made easy! In this article, we’ll dive into the process of implementing sign-up with phone after having email in AWS Cognito. Yes, you read that right – we’ll show you how to allow users to sign up with their phone number after they’ve already registered with their email address.
Why Implement Phone Sign-up?
In today’s digital age, users expect seamless and secure authentication experiences. By offering phone sign-up as an option, you can provide an additional layer of convenience and security for your users. This is especially useful for users who may not have access to their email accounts or prefer to use their phone number for authentication.
Prerequisites
Before we dive into the implementation process, make sure you have the following:
- An AWS Cognito user pool set up with email sign-up enabled
- A basic understanding of AWS Cognito and its features
- A development environment set up with the AWS Cognito SDK
Step 1: Enable Phone Sign-up in AWS Cognito
To enable phone sign-up, navigate to your AWS Cognito user pool and follow these steps:
- Go to the “Attributes” tab and click on “Edit”
- Scroll down to the “Phone” section and select “Phone number” as an attribute
- Click “Save changes” to save your updates
Note: Make sure you have the necessary permissions to edit the user pool attributes.
Step 2: Configure Phone Verification
To configure phone verification, follow these steps:
- Go to the “Account recovery and verification” tab and click on “Edit”
- Scroll down to the “Phone verification” section and select “Required” as the verification method
- Choose your preferred SMS messaging service (e.g., Amazon Pinpoint or Twilio)
- Configure the SMS messaging service according to the provider’s instructions
- Click “Save changes” to save your updates
Note: Make sure you have set up your SMS messaging service and have the necessary credentials.
Step 3: Implement Phone Sign-up in Your Application
Now that we’ve configured phone sign-up in AWS Cognito, let’s implement it in your application. We’ll use the AWS Cognito SDK to handle the phone sign-up process.
Here’s an example of how you can implement phone sign-up using the AWS Cognito SDK in JavaScript:
[code]
// Import the AWS Cognito SDK
const AWS = require(‘aws-sdk’);
const cognitoidentityserviceprovider = new AWS.CognitoIdentityServiceProvider({
region: ‘your-region’,
accessKeyId: ‘your-access-key-id’,
secretAccessKey: ‘your-secret-access-key’,
});
// Define the phone sign-up function
async function phoneSignUp(username, phoneNumber) {
try {
// Create a new user in the user pool
const createUser_pool = {
UserPoolId: ‘your-user-pool-id’,
Username: username,
Attributes: [
{
Name: ‘phone_number’,
Value: phoneNumber,
},
],
};
const createUserResponse = await cognitoidentityserviceprovider.signUp(createUser_pool).promise();
// Get the user’s id token
const getIdToken = {
AccessToken: createUserResponse.CodeDeliveryDetails.AttributeName,
};
const getIdTokenResponse = await cognitoidentityserviceprovider.getIdToken(getIdToken).promise();
// Verify the user’s phone number
const verifyPhoneNumber = {
AccessToken: getIdTokenResponse.AuthenticationResult.AccessToken,
Code: ‘123456’, // Replace with the verification code sent to the user’s phone
};
await cognitoidentityserviceprovider.verifyPhoneNumber(verifyPhoneNumber).promise();
// Return the user’s id token
return getIdTokenResponse.AuthenticationResult.IdToken;
} catch (error) {
console.error(error);
}
}
// Call the phone sign-up function
phoneSignUp(‘username’, ‘+1234567890’);
[/code]
Note: Replace the placeholders with your actual AWS Cognito credentials and user pool ID.
Step 4: Handle Phone Verification
Now that we’ve implemented phone sign-up, we need to handle phone verification. We’ll use the AWS Cognito SDK to verify the user’s phone number.
Here’s an example of how you can handle phone verification using the AWS Cognito SDK in JavaScript:
[code]
// Define the phone verification function
async function verifyPhoneNumber(username, verificationCode) {
try {
// Get the user’s access token
const getUserAccessToken = {
AuthFlow: ‘REFRESH_TOKEN_AUTH’,
ClientId: ‘your-client-id’,
UserPoolId: ‘your-user-pool-id’,
AuthParameters: {
REFRESH_TOKEN: ‘your-refresh-token’,
},
};
const getUserAccessTokenResponse = await cognitoidentityserviceprovider.getUserAccessToken(getUserAccessToken).promise();
// Verify the user’s phone number
const verifyPhoneNumber = {
AccessToken: getUserAccessTokenResponse.AuthenticationResult.AccessToken,
Code: verificationCode,
};
await cognitoidentityserviceprovider.verifyPhoneNumber(verifyPhoneNumber).promise();
// Return a success message
return ‘Phone number verified successfully!’;
} catch (error) {
console.error(error);
}
}
// Call the phone verification function
verifyPhoneNumber(‘username’, ‘123456’);
[/code]
Note: Replace the placeholders with your actual AWS Cognito credentials and user pool ID.

FAQs
Q: What is the difference between phone sign-up and email sign-up?
A: Phone sign-up allows users to sign up with their phone number, while email sign-up allows users to sign up with their email address.
Q: Can I use phone sign-up with existing email users?
A: Yes, you can use phone sign-up with existing email users. AWS Cognito allows you to link multiple authentication providers to a single user account.
Q: Is phone sign-up secure?
A: Yes, phone sign-up is secure as long as you implement it correctly using the AWS Cognito SDK and follow best practices for authentication and authorization.

Frequently Asked Question
Get answers to your burning questions about implementing sign up with phone after having email in AWS Cognito!
What is the first step to implement sign up with phone after having email in AWS Cognito?
The first step is to enable phone number sign-up in your AWS Cognito user pool. To do this, go to the AWS Cognito console, navigate to your user pool, and click on “General settings”. Then, click on “Attributes” and select “Phone number” as an attribute. Finally, make sure “Allow phone number sign-ups” is enabled.
How do I configure the phone number verification process in AWS Cognito?
To configure the phone number verification process, you need to set up a SMS role in your AWS Cognito user pool. This role will allow AWS Cognito to send verification codes to your users’ phone numbers. You can do this by going to the “CustomAttributes” tab, clicking on “Actions”, and selecting “Create SMS role”. Follow the instructions to set up the role and configure the verification process.
Can I use both email and phone number as identifiers for users in AWS Cognito?
Yes, you can use both email and phone number as identifiers for users in AWS Cognito. This is known as an “alias” in AWS Cognito. When a user signs up with their phone number, AWS Cognito can use the phone number as an alias for the user’s email address. This allows users to log in with either their email address or phone number.
How do I handle phone number verification failures in AWS Cognito?
To handle phone number verification failures, you can use AWS Cognito’s built-in retry mechanism. You can configure the number of retry attempts and the delay between attempts. Additionally, you can also use Amazon Lambda functions to handle verification failures and implement custom logic to handle failed verifications.
Are there any security considerations I should keep in mind when implementing sign up with phone after having email in AWS Cognito?
Yes, there are several security considerations to keep in mind. Make sure to implement proper input validation to prevent spam or phishing attacks. Also, use SSL/TLS encryption to secure the communication between your application and AWS Cognito. Finally, ensure that you comply with relevant regulations such as GDPR and CCPA when handling phone numbers and user data.
