We show you how you can activate two step verification on Google, Facebook and Twitter. And we tell you where to look for instructions for other services.
We have talked a lot about security, from how we can create strong passwords or use an administrator for them, to how to keep our mobile phone safe. Users have many tools at hand to protect our data from malicious third parties, and the two step verification It is one of the most effective.
Companies like Google, Facebook, Twitter and Dropbox, to name a few, have incorporated this layer of security into their services. If you don’t know what it is, it’s something that’s been around since the 1980s, a method to identify a user using a combination of two different components: information that the user knows and something that the user possesses. A simple example of this is ATMs: what the user has is the card, and what the user knows is the pin. Two step verification has spread widely on the Internet to prevent anyone from accessing an account just by knowing the password.
There are many services that offer two step verification and if you want to know each and every one of them, you can check the website Two Factor Auth List which offers a list organized by categories with all the information about it, including a link with instructions to activate the feature on each site. Meanwhile, here we will explain how to activate two step verification on Google, Facebook, Twitter.
Google’s two step verification is one of the most complete. It offers the ability to receive text messages and phone calls anywhere in the world. There are also other options such as using a secondary phone number in case the primary one is not available, downloading backup codes that can be used only once, and if you want you can use your mobile or desktop devices as a form of verification.
To activate the service, go to this page dedicated solely to explaining what two step verification consists of. Once there you have to press the “Start” button at the top. On the next screen you will be asked to log in. If you have never set up anything in the security area of your account, the next step will be to do so, which will involve adding a mobile phone number. However, in newer accounts, all of this information is requested by Google repeatedly, so the system will most likely tell you to verify your mobile number by sending a code via SMS or a call.
You have to wait to receive the code and then enter it in the box indicated on the website. The next step will tell you that if you log into your account from a reliable or trusted computer, you will not be asked for a code, but otherwise, you will need to have your cell phone at hand. This also means that If your phone is lost or stolen, you will need to go to one of the trusted computers to log into your account and change the settings. The last step is to activate two step verification.
When you finish you will be sent to another page where you can configure an alternate phone number, security codes to download and create security keys. From this link, you can deactivate two step verification if necessary. From now on, every time you log in to your Google account you must enter your password and the code sent to your mobile.
On Facebook, two step verification also depends on the mobile phone and can be configured by entering this link once you have logged in with your account. There you should look for “Login approvals”. To the right of this is a link that says “Edit” that we need to click on. Then we will see that we can check a box that will make Facebook ask for a security code every time you access your account from a browser that it does not know.
If you do not have a mobile number set up, you will now be prompted. If yes, you will only be sent a code by text message and then you will have to enter it in the box that appears on the Facebook page. Press “Continue” and then enter your password, which will confirm the change. Then you can enter the configuration again and you will see that You have ten codes available that you can print in case you go on a trip and don’t have your cell phone at hand. These can only be used once. To reverse this two step verification, simply edit “Login Approvals” again and uncheck the box.
To use two step verification for your Twitter account, you’ll need to do two things first:
- Confirm your email address, which is usually done right after creating your account thanks to an email that arrives to you automatically. You can go to your Account Settings to update your email if necessary.
- It is necessary to add a mobile number, which you can do from this link, after logging in to Twitter. A verification code will be sent to you via SMS immediately to activate the phone number.
After these two steps you can go to the Security area of your Twitter account and you must check the first box that indicates Login Verification. Twitter will send another test message to your mobile. If you received the text message, indicate yes, and if not, you will need to check your phone number settings again. The next step will be to enter your password, which will save the changes and activate the two step verification service. Now you will see that you also have the possibility of requesting a backup code in case you do not have your mobile phone at hand and also generating a temporary password to log in with Twitter.
In the case of Twitter, You’ll always be prompted for a verification code, even when you sign in on a known device. To deactivate this service, you just have to uncheck the same Login Verification box.
