Every application needs to have authentication implemented to deal with individual user accounts. Strong authentication is essential to keep the user data secure. Otherwise, it can fall prey to hacking attempts.
You can use multiple ways to ensure you have developed a secure way to log in and log out your users. Firebase provides a quick and easy way to set up an email/password authentication. You can also use JSON Web Token to encrypt the user credentials or use a Web API designed for web authentication.
This web API, also known as WebAuthn, uses asymmetric cryptography, widely known as public-key cryptography. Here you have a public and a private key for encrypting and decrypting messages to protect them from unauthorized access. The public key is present on the server. Even if the hacker gets access to the public key, they can not decrypt the data without the private key present on the user’s device.
This API does not require users to enter credentials like their passwords; instead, a public-private key is created for a website.
Here are some of the benefits of using this API for authenticating users:
Let’s take a quick look at some use cases of WebAuthn API:
