Cybersecurity threats persist every single day across a plethora of online platforms and software. In today’s age, a password alone isn’t enough to ensure safety for your valuable account. Two-Factor Authentication (2FA) is steadily becoming the standard for online protection because it’s both effective and convenient. There’s a chance you’ve already seen it- confirming a login through a texted code, or linking several emails to one account.
But what exactly is two-factor authentication, and when should it be used? In this guide, we’ll walk you through what two-step verification is, how it protects users, and when you should consider enabling it.
What is Two-Factor Authentication?
2FA (also known as dual-factor authentication) is a security process that requires two different confirmations to verify the user’s identity when logging into an account. Even if someone else has access to your password, they are still unable to get into the account.
The process typically combines the password with another sort of identification separate from that account, such as a phone number, fingerprint, or temporary code.
How does Two-Factor Authentication Work?
There are several secure ways multi-factor authentication is used.
– SMS code (Text Messages): You will receive a code via text, and will need to enter this code to finish the login process
– Authentication Apps (Google Authenticator, MS Authenticator): These generate new codes frequently to authenticate yourself. They are generally more secure than SMS.
– Push Notifications: Additional Approval of login on a device
– Biometrics: Fingerprints, facial recognition, retina scan, etc.
– Hardware: Physical devices which serve as keys; must be plugged in or synced to verify identity and log in.
When Should You Use 2FA?
In reality, you should use secondary verification whenever it’s available. Most services offer this to protect users, and it’s a convenient method to protect personal information.
Here are some instances where an extra layer of security is an absolute must for online protection:
– Email Account
– Financial Services
– Cloud Storage
– Social Media
– Shopping Accounts
While secondary authentication can seem like an inconvenience at first, it is truly one of the best ways to secure your information on the internet. It can block the majority of phishing, prevent unsolicited access, and generally give you peace of mind when using the internet. Often, two-factor authentication ends up being the only thing standing between a user and their information being exposed.
