BrowserID – What is it?

BrowserID picture

BrowserID is a user identification method wherein the user takes the help of an email for web authentication. The core idea behind using a unique BrowserID is to prevent creating a username for different websites and then becoming confused. Instead, it promotes remembering your verified email address and using it as identity proof for every website you visit or log in to.

Before using it, understand that it will work only if the browser is compatible with Browser ID JavaScript API.

How Does It Work?

In technical terms, BrowserID is a Verified Email Protocol-based application built on public/private key cryptography. It’s decentralized and works in cross-browser. Websites using this facility allow visitors to prove their identity using an email.

  • Before accessing any web application or website, a user must provide a valid email address.
  • The targeted website will then share an email featuring a link.
  • Users will have to click on the link and prove their identity.
  • Finally, they are allowed to access the website.

What Are Its Pros and Cons?

You must have already understood ID browser or BrowserID from the previous section. Let’s now discuss its positive and negative sides.

BrowserID is a step towards improved web security and brings multiple benefits. For instance:

  • Verification is required once, and you can access the website again and again
  • The Verified Email Protocol, the base of Browser ID, comes with in-built security
  • Anyone can use it, and you can even implement it natively in the browser

But there are hidden dangers as well. If your BrowserID is stored on a device and is accessed by threat actors, you can lose control over it.

To make things worse, when threat actors get a device ID from a browser, they can use it to access websites and take actions like making transactions, sending emails, making purchases, and so on. Hence, one must always use it with solid security measures, for instance, VPN services. They have proven to be reliable tools for those who want to protect themselves online.

Is It Always A Bliss?

We agree that with a unique Browser ID, single sign-in is easy. However, it can be a headache if an ISP or browser saves it, making it prone to misuse.

If you’re not careful, the possibility is that your Apple ID was used to sign in to iCloud via a web browser, and your crucial data was leaked.

If that’s not what you want, you must learn about ‘how to remove ID browser history?’ immediately. Well, we’re coming on this next.

VPN, or Virtual Private Network, is an advanced technology that prevents logging. Once this tool is in place, the traffic becomes highly encrypted, and all the crucial details are removed from it. Thus, the traffic that a website receives from the users’ side hardly features any sensitive information. Also, the real IP address is replaced with a dummy one making it impossible to find out the real location of the visitor.

This way, one can prevent logging of Browser ID or any other crucial details, exposure of which could cause troubles, and enjoy safe browsing.

Ending Notes

BrowserID is an intelligent solution for simplified single sign-on. There is no need to create user IDs for different websites with it. However, it is not sufficient for enhanced security when used standalone. It’s better to club it with a VPN and keep all hassles at bay. With a VPN, you can also ensure your Browser ID is not saved elsewhere.
