When it comes to online security, the only thing we’re told not to reuse is our passwords. However, in reality, passwords rarely go alone and are almost always paired with an email address — something that travels everywhere in plain text but rarely gets the same level of caution.
By handing out our personal email addresses, we effectively give away our digital identifier, which can be used to trace us back. Just as you shouldn’t reuse your passwords everywhere, your personal email shouldn’t be used on every platform you sign up for, either — especially since email addresses are exponentially harder to replace if they end up in a leak.
