Remember when you opened your last Gmail account? Filling in your personal details, a username and password would have been insufficient. You typically see prompts to provide your mobile number or an alternate email address to which they would send a code to in order to activate your account. Although bothersome when you are trying to open an email account quickly, it is helpful in the long-term. Besides Gmail, there are several instances where you can make use of the security provided by this excellent system, as many companies are making it a standard for signing up.
Two-factor authentication requires users to enter their password and confirm their identity via a code which is automatically sent via text message to their mobile phone. As a result, hackers who have simply stolen your password cannot do much with it, unless they have your mobile phone as well.
Never open an email attachment unless you are 100% sure of its content.
.A common rule of thumb states that if you receive an attachment via email from a sender you do not know or have not corresponded to with previously, just delete it. If the email is urgent, the sender will always find an alternate way of contacting you.
Email attachments are one of the most common ways through which hackers download malware to computer systems. Remember the “ILOVEYOU” virus which wrecked havoc in 2000?
This rule applies to even social media messages. If you receive a message or attachment via Facebook or Whatsapp, for example, from someone you do not know, simply delete the message. If it is from a friend, confirm with them that they had sent you something. Some viruses propagate via a person’s contact list, and receivers, since they know the sender, download the attachment.
