Authentication systems play a crucial role in providing a seamless and secure user experience.
An authentication workflow typically involves two processes: sign-up and log-in.
As the number of online services increases, people create accounts, and each account requires unique login credentials.
However, this makes it easy to forget or confuse login credentials.
Instead, you should tailor the approach you choose to meet the specific needs of your app.
Next, installAxios, a JavaScript HTTP request library.
you might find the project’s code in thisGitHub repository.
Create a Login Component
In the src directory, create a newcomponents/Login.jsfile and add the following code.
It first verifies the user by checking their email in the database before generating and sending the OTP.
Finally, it updates the UI with the OTP page.
It checks that the entered code matches the one stored in the context object.
If it’s valid, it displays the password-reset page.
Conversely, it shows an alert prompting the user to have another go or resend the OTP.
Finally, render the input JSX elements.
It will then update the UI if the request is successful.
It also includes a function that handles page navigation with ease without needing to re-render whole components.
To finish, you should probably configure the database connection and define the data models for your user data.
Use the code in this repository toset up the database connectionanddefine the data models.
Define the API Routes
A backend service ideally has several routes that handle clients' HTTP requests.
Create a newcontrollers/userControllers.jsfile and add the code below.
Use the code in this repository todefine controllers for the email verification and update-passwordAPI routes.
It sets up a transporter using your own Gmail account and password.
To get your Gmail app password, you need togenerate an app password in your Google account controls.
Youll then use this password in place of your regular Gmail password for authenticating the Nodemailer.
