Your email account is one of the most important sources of personal information there are. If someone were to break into it, your confidential data could be decisively compromised. You should have a minimum of two email accounts, with one being a secure backup in case one email account is compromised and you need to gain access back to it.
This is also a good idea to protect your identity, as you generally want to keep your private and work emails separate, the latter of which will commonly contain your name or some form of personal information. You don’t want your name in your private email address that you use for everyday, non-work-related things, so it’s a good idea to have both a private and professional-sounding business email address.
