Your email is a digital treasure chest. Not only does it contain everything from your contacts to your calendar to personal information like doctors' appointments and employment history, but a hacker could also use the "forgot password" feature to take over a long list of your other accounts.
Once a hacker has gained control of your email, they could potentially lock you out of your own accounts, drain your financials, and commit identity theft, among other malicious behaviors. That makes it a particularly attractive target for threat actors, which means you'll want to make sure it's secure at all times.
