How to secure your accounts with two-factor authentication

How to secure your accounts with two-factor authenticationTwo-Factor Authentication is an important topic, and for good reason. It provides an additional layer of security for our online accounts by requiring second login criteria, on a separate device. We could explain it as “a key for our key”, sort of.

How to secure your accounts with two-factor authentication

Two-factor authentication works differently depending on the online account we use. techjustify also has slightly different names in some places. So, here is a guide to enable this security feature on different online accounts.

How does two-factor Authentication work?

Two-factor authentication works by locking out an account with two separate “factors” . In this case, a factor is “something you know” (for example, a password), “something we have” (for example, our phone) or “something that we are” (for example, a fingerprint). Thus, we have better protection by combining two of these factors.

If one of our accounts uses two locks of the same factor, we have two-step authentication. For example, our password and an additional security question (think mother’s maiden name, pet’s first name, etc.), are both “something you know”. While that’s not bad, on its own, Full Two-Factor Authentication is more secure.

How do I configure two-factor authentication?

Enabling this feature is usually found in the account security settings.

In order to save you time, below are direct links to the techjustify authentication setup pages of the most important services on which to enable it. 🙂
