Cybersecurity experts warn: This common email habit is a gift to hackers

Using your email address as your username has become the standard. In many cases, you simply enter your email address and choose a password. Some services remove the need for a password altogether, allowing you to register using just your email address and a onetime code sent to it. Others offer the option to connect your account directly to your Google or Apple identity. As we scroll, shop, apply, and register across services, our email address quietly becomes our identity everywhere, from shopping platforms to banking to travel. Over time, more and more of our activity starts pointing back to a single account. While it all feels convenient, there is an issue we often forget. Our email is not just an access point. It holds sensitive information about us—both in what we receive and what we send—and it is tied to many, if not most, of the services we use. We rely on it to receive one-time codes, confirm actions, and reset passwords. It is also where we communicate with accountants, bankers, doctors, and other providers, as well as for personal communication. Over time, this turns our email into more than just another account. It becomes a central point of access, connected to multiple parts of our lives. Your email is your identity Every time you use your email to log into a service, you are connecting another account directly to it. Over time, more and more services become tied to that same identity, and your email becomes the place that links them all. As a result, one email account ends up controlling access to many different accounts, across services that have nothing to do with each other. If someone gains access to your email, they can use standard flows, password resets, login confirmations, and verification emails to access those connected services. In addition, they gain access to a large amount of personal information, including medical records, financial details, addresses, contacts, and private communication.
