How to Check If Your Phone Number and Email Have Leaked Online?

There is no way to get complete details of a data breach or your details that were hacked. However, you can check if your email or phone number was leaked in a data breach recently or previously using the following methods.

Method 1-  Using ‘Have I Been Pwned’ Website

“Have I been Pwned” is a website where you can find if your email ID and phone number were part of any data breach. Here’s how to use the free tool:

1. Go to the Have I Been Pwned Website on your phone or computer.

2. On the webpage, enter your email or phone number in the international format and click on the ‘pwned?’ tab.

When you scroll down, you will also find all the web pages through which your data was leaked.

Method 2- Using the Avast Hack Check Tool

You can also use Avast’s Hack Check tool to check if your email address has been leaked in a data breach. One thing to be noted is that this tool doesn’t let you check if your phone number is leaked. To check for email address leaks, follow these steps:

1. Visit Avast’s Hack Check tool page and enter your email address in the box.

Method 4- Using The News Each Day Tool (US Only)

According to the website, to protect user privacy, it generates random phone numbers starting with the same five digits as your number and 99 such fake numbers and one real number to the server. So it can never be known which is your actual number.

How to Stay Safe Online?

It’s always a good idea to change your passwords whether your details have been compromised or not. Also, set a strong and unique password you haven’t used anywhere else. Apart from that, here are some other tips to further secure your several online accounts like email, Facebook, Instagram, etc.

  • Always use 2FA (two-factor authentication) for your Facebook, Instagram, and all other services offering 2FA. This will reduce the risk of hacking your account.
  • Also, remove phone-based 2FA and try to set up the 2FA app if the account allows it.
  • If you think your phone number has leaked several times earlier, consider changing your phone number as well.
  • Also, keep yourself updated with the latest and most common online scams.
  • You can also safeguard your data by using a more secure messaging app.
