Email has been one of the most widely used ways of sharing data among professionals. Therefore, hackers have also become experts at retrieving data by breaching email security. The problem arises when companies don’t pay much attention to updating their email security methods and end up getting scammed.
As recorded by the Internet Crime Report, in 2020, there were 19,369 complaints about the Business Email Compromise (BEC). It resulted in adjusted losses exceeding $1.8 billion.
Two-factor authentication is built to make email accounts secure by adding a layer of security over username and password. The second layer of security can be anything like a fingerprint, a code, or a security token.
Here’s a guide on how to set up Two-factor authentication for emails and why it is important to make your accounts secure.
Key Takeaways
- Email security is critical, as hackers are continuously innovating ways to breach it.
- Two-factor authentication (2FA) significantly enhances email account security by requiring an additional verification step.
- Common methods of 2FA include SMS codes, authentication apps, biometric verification, and hardware tokens.
- While 2FA improves security, it can also introduce inconveniences and dependencies on secondary devices.
- Investing in robust email security measures, including 2FA, is essential to protect against phishing and other cyber threats.
What is About Two-factor authentication?
Two-factor authentication (2FA) is an email security method, that requires users to provide two different authentication factors to verify their identity. used to enhance email security in addition to a strong password. It adds a randomly generated code to the login process, which you have to add every time before logging in to your account.
Once the code is activated, you can access your email accounts by entering this. This dual-factor authentication protects your associated email accounts as well as other applications. Even if someone else gets to know your password, they can’t log in without the code.

How Two-Factor Authentication (2FA) Works
Here is how 2FA typically works:
- The first thing you need to do is to enter your username and password. It is the most common form of authentication. It involves something the user knows.
- After the username and password are entered and verified, the system will request a second factor. This is usually something the user has such as a text message or a push notification.
- Choose the method that seems most appropriate. Then enter the code from your phone, hardware token, or approve the push notification. If both the password and the second factor are correct, the system grants access to the user.
Common 2FA Methods
Here are some common methods used for 2FA:
- SMS Text Message: A code is sent to your phone via text message.
- Authentication App: Apps like Google Authenticator generate a code that changes every few seconds.
- Biometric Verification: This uses your fingerprint, face, or iris scan to verify your identity.
- Email Verification: A code is sent to your email address.
- Hardware Token: A small device generates a code you can use to log in.
- Push Notification: A notification is sent to your smartphone, and you approve the login by pressing a button.
