In today's digital world, we all have countless online accounts for many different services – email, social networks, shopping, banking, etc. Both these accounts may be a challenge. It was the time when “Sign-in with Google” became helpful. This feature allows you to use your Google account to log in to other websites and applications easily. Let's analyze how this feature works simply.
When you use “Sign-in with Google” to access the website or application, one of the main benefits is that Google never shares your password with the website or application. The following is a deeper view of how this process works and related web technologies.
What is Sign-in with Google?
“Sign-in Google” is a service provided by Google that allows you to use your Google account to log in to other websites and applications. Instead of creating a new username and password for each website, you can use your Google login information. This makes the login process faster and safer.
How does this feature work?
- Select Sign-in Google: When accessing a website or opening an application that supports login options with Google, you will often see a button with the content “Sign-in Google”. Click this button to start the process.
- Google authentication: After clicking this button, you will be redirected to the Google login page (if you have not logged in). Here, you will enter your Google email address and password.
- Grant: After you log in, Google will ask if you want to grant the website or application of access to some of your Google account information, such as email addresses and avatars. This step is very important for privacy and security, because it ensures you know the data you are sharing.
- Backward: After you grant the right, Google will send a token (security code) back to the website or application. This token gives the website or application that you are an account holder.
- Has granted access: Website or application that gets tokens and login for you with your Google account information. Now, you can use the service without having to remember the new password!
What is the web technology behind “Sign-in with Google”?
The technology that helps “Sign-in Google” become feasible to be called OAUT 2.0. The following is a simple explanation of how it works:
1. OAUTH protocol 2.0
- OAuth 2.0 is an open standard for authorization. It allows users to issue websites or applications to limit access to their information without disclosing passwords.
- OAuth 2.0, short for “Open Authorization”, is a standard designed to allow a website or application to access resources by other web applications on behalf of users. It replaced the Oau 1.0 in 2012 and is now a practical industrial standard for online authorization. OAUTH 2.0 provides access to the agreement and limit the actions that guest applications can perform on resources on behalf of users without sharing their login information.
2. Information flow
- Request: When you click on “Sign-in Google”, the website or application will send a request to Google.
- User authentication: You will be redirected to Google's login page, where you enter your login information.
- Authority: Google requires you to allow specific data sharing (for example, email and your profile information) with the website or application required.
- Token release: If you grant your authority, Google will send an authorization code or token to return to the website or application. This token is a temporary, safe code that the website uses to require the necessary information from Google.
3. Access token
- Use: Token allows the website or application to access certain data from the Google account (as issued) without seeing your password.
- Security: Token is designed to survive in a short time and dedicated to the website or application, which reduces the risk of wrong use.
“Sign-in Google” simplifies the login process, making the process faster and safer. By using a Google account to log in to many different services, you save time and reduce the trouble when you have to manage multiple passwords. Remember to keep your Google account safely and you will have a smoother and safer online experience. Wish you have fun browsing!
