Vue Js OTP Authentication: Vue.js is a popular JavaScript framework for building web applications. One common use case for Vue.js is implementing OTP authentication for user login. Here’s an overview of how you can implement Vue Js OTP authentication:
- Create a form for the user to enter their phone number or email address.
- When the user submits the form, send a request to your backend API to generate and send an OTP to the user’s phone number or email address.
- Display a form for the user to enter the OTP they received.
- When the user submits the OTP, send a request to your backend API to verify the OTP.
- If the OTP is verified, log the user in.
How to Implement Vue Js OTP Authentication?
For Vue Js OTP Authentication, the following example demonstrates how to use the sendOTP and verifyOTP methods to implement OTP-based authentication in your Vue.js application.
To begin, the sendOTP method is used to send a POST request to the /send-otp endpoint on your backend API. This request includes the user’s contact information (such as phone number or email address) as the payload. Upon receiving the request, the backend system generates an OTP and sends it to the user’s contact information. If the request is successful, the otpSent flag is set to true, which displays the OTP verification form.
Next, the verifyOTP method sends a POST request to the /verify-otp endpoint on your backend API, including the user’s contact information and the OTP they entered as the payload. The backend system then verifies the OTP and returns a response indicating whether the OTP was valid or not. If the OTP is verified, the authenticated event is emitted to notify the parent component that the user is authenticated.
Keep in mind that this is a basic example, and you will need to address various details, such as handling errors and providing user feedback. Furthermore, the backend system must be implemented separately to generate and verify Vue Js OTP Authentication.
