I just received a newsletter from Mozilla on tips to improve online privacy. https://blog.mozilla.org/firefox/four-ways-to-protect-your-data-privacy/
Here is an excerpt from the article:
Email addresses are also a hot commodity for data collection, and with good reason. Most people have only a few email addresses, yet they have dozens, if not hundreds, of online accounts connected to them. Your email address is a unique identifier — after all, you’re the only one with it. Think about all of the information someone could glean by connecting everything you do to your email identity.
How we can help right now:
Firefox Relay is a smart solution for shielding your email. With just a click, you can create an email alias that forwards to your inbox, keeping your actual email address private. Plus, it helps cut down on spam and hacking attempts.
While I agree that I register lots of websites with the same email, but I’m not sure if someone will know my identity or all websites I registered with just by knowing my email. Unless if those websites are under the same company. Like Facebook and Instagram.
What is your thought on this?
