Two-factor identification for security

As the number of breaches in the cloud increases, two-factor identification is becoming a popular method to protect data. With this type of authentication, a user must provide something they know (a password) and something they have (a one-time code typically sent via text message or automated phone call.)

What kind of solutions is 2FA?

Such a system would give people using cloud services, such as Google Drive or Dropbox, the same level of protection they have with traditional bank accounts.

Two-factor authentication, which banks also use, can also protect data stored in the cloud.

This multi-factor authentication may be familiar from online banks, where a one-time code is required to initiate a transfer, in addition to a password, via SMS.

You can also use the same method to protect your Google Account: go to your account settings via, then click on the Two-factor authentication link on the Login and security page. Follow the instructions here to activate the service. If you sell or lose your phone, you’ll be able to disable your device for two-factor sign-in from the same place.

Did you know?

Did you know that every time you log in to a website, you’re giving your password to the site whether or not you intend to? That’s because when you type in your username and password, the server will send a cookie saying, “Hey, I’m logging in,” and then ask for that cookie later. The session cookie can be stolen by a hacker who’s watching your internet traffic. Two-factor identification is necessary to make sure hackers can’t access your information. This means that when you log in to a website, it’ll ask for something besides just a username and password. It could be a code sent to your cellphone via text message or an email that expires after a certain amount of time.


There are six different types of two-factor identification. The most common type is the use of an external token, which can be a device or app. These devices generate unique codes that are sent to the user’s phone. They also have one-time passwords that can be used when logging in to accounts. For security reasons, this process should be repeated every 30 seconds.

Given all the talk about data security, it’s easy to forget that companies already have powerful strategies for guarding their confidential information. One of these is two-factor identification, which requires you to use two pieces of identifying information (like a password and a code sent via text message) in order to log in. The article provides tips on how this type of security can be effective for both businesses and individuals.
