Why is the security of my mailbox so important?

With a hacked email account, criminals can impersonate you on the web. In this case, we speak of identity theft. In addition, sensitive information such as login credentials or bank details can be recovered: hackers can thus access your contacts, can make online purchases in your name or use your account to send spam or Trojans. This can cause considerable financial damage. For example, an online store will take money from your account without you having made any purchases. Since these are purchases made in your name, you will be held accountable for these fraudulent activities.
