Is it safe to Login to other Websites or App with Facebook Login?

It’s completely safe to log in to websites and apps that require the account you have created on your Facebook account with Facebook Login. Large tech business and platforms (e.g., Google, Facebook, Apple, and Twitter, etc.) utilize a standard known as OAuth. It lets third-party websites access and retrieves certain bits of information from these major websites to verify users.

Before we dive deeper into the mystery of websites/Apps login, we’ll take a quick look at the mechanism at work on a website when “With Facebook Login” can be used.

What exactly is OAuth?

With Facebook Login and other third-party Social Media Login uses Oauth, and The OAuth protocol is used to help large websites (websites with a huge number of users like Google, Facebook, Twitter etc.) give access to its users’ data to third-party websites and applications, without sharing users’ passwords or other personal, sensitive information.

In terms of more technical terminology, OAuth can be described as an open-standard for security delegation which is an open standard that permits big companies such as Facebook, Google as well as Microsoft to allow users to share selected information with third-party websites and applications, while safeguarding the private information of the users.

OAuth is typically utilized by applications or websites such as Facebook, Google, Twitter, and Microsoft, which all have huge databases of users.

A hypothetical scenario where “With Facebook Login” is perfectly suited

Let’s say you’d like to make quick edits to an image on the Internet. You visit a website such as Crello, which allows you to modify your image right in the browser window. But there’s a catch that if you want to avail of the services offered by Crello, Crello requires you to sign up.

The image needs only five to six minutes of editing, and you won’t think about spending longer filling out a signup page by hand. You might be bored or in haste with insufficient time to complete an application or manual signup. There are plenty of people who are irritated at the glance of a signup page!

In all honesty, I believe it’s reasonable to get annoyed. In today’s fast-paced, modern world in which the average attention span for the average Internet user is just under one minute when a user plans to spend just an hour or so on your site to signup and create accounts from scratch is quite a task! Users may abandon a “demanding” website and look for one which doesn’t ask the user to signup to do any reason.

OAuth and “With Facebook Login” help you avoid the difficulties associated with Registering.

The majority of websites (that require an account) recognize the behavior of users when they need to open new accounts. To ensure they don’t miss out on these reluctant users, these websites use the OAuth standard (With Facebook Login) in their systems.

A third-party site that is OAuth-enabled (e.g., Crello) generally offers two options. You can choose to sign up using the standard method, i.e., by filling an online form or signing up with Facebook, Apple, and Google.

Note the two ways of registering on the application: one permits users to access their account on social networks, and the more conventional method uses your email address.

Crello, like other websites on the Internet, recognizes the fact that Facebook, Google, and Apple have a huge number of users. (i.e., the amount of people who use their services ranges from billions to billions) and puts its bets on the likelihood that you may be a user on one or the other of those sites (Apple/Google/Facebook).

So instead of asking the new user to fill out a signup page manually, which can take up to 10 minutes dependent on the speed and the ‘annoyance level of the user Crello simply requires users to signup using your Google, Apple, or Facebook account.

What is the “With Facebook Login” process?

This is how the “With Facebook Login” and “OAuth standard” functions:

Imagine that the user (the user) have to sign up or create an account on a third party application or website (e.g., Crello).

Then, click the “Sign With Facebook.

It then redirects the user to Facebook.com and determines if you’re already signed into Facebook. If not, it prompts you to input your password and username to log in to your account.

After logging into your account, it displays an uninvolved dialog box that explains the type and quantity of information you’ll share with a third party’s website. If you’re comfortable sharing the necessary information with the third-party website, click the ‘Continue button.

The data that Crello is a website owned by a third party is looking to gain access to through Facebook.

In the event that you’re happy with the information that will be shared with a third-party website, you’re able to change the settings you’re using.

This time, Facebook redirects you to the relevant third-party site using an authentication code. This is Facebook’s way of telling the site that the user has a valid account for me’.

The website is now showing Facebook the unique code it obtained at the time it registered through Facebook to establish itself as an authentic site or application. Facebook utilizes that code to verify the legitimacy of the website, and as a result, it provides an access token for the website.

This token that websites use to access restricted or limited access to certain account details, typically consisting of your email address, name as well as gender and others.

This is basically how OAuth can help big websites such as Google, Apple, or Facebook provide restricted access to users’ specific information to third-party apps. To learn more about the whole procedure, visit the official site for Facebook which explain this system in depth (links are included in the references section on Facebook’s page about “Login with Facebook”).

With Facebook Login or Login With Facebook summarized
