Virtually every account you own on the Internet is hacked – and one of the easiest ways to add an extra layer of security is to enable two-factor authentication. The process, also known as two-step verification or 2FA, gives web services secondary access to the account holder (you!) To verify a login attempt. Usually this is a telephone number and / or an e-mail address.
Although 2FA does not completely protect you from potential hackers, this is an important step in preventing unauthorized users from accessing your account. To enable 2FA for your accounts on the Internet:
Editor's note, January 23: If you have a Nest camera, you can activate 2FA immediately. Recently, there have been a number of "hacks" that reuse existing compromised passwords to scare Nest Cam owners and so we find this how-to today with instructions on how to do this is. Note that other camera brands currently do not seem to support 2FA.
The steps differ slightly depending on how your iOS software is upgraded. If you are using iOS 10.3 or later, you can enable 2FA for your Apple ID by going to Settings> [Your Name]> Password and Security. You can enable 2FA to get an SMS with a code every time you log.
If you are using iOS 10.2 or earlier, the settings are under "iCloud"> "Apple ID"> "Password & Security".
Click the Apple icon in the upper-left corner of your window, then click System Preferences> iCloud> Account Details. (You can shorten this step by typing iCloud in Spotlight.) Click Security. The option to enable 2FA is displayed.
The remaining steps of iOS or Mac are the same. You can choose to have Apple send you a six-digit verification code by SMS or phone call.
Although you can access Instagram through a web browser, you can only enable 2FA from your mobile app at this time. Go over your profile and click on the Hamburger menu in the upper right corner. In the "Account" section, you should see "Two Factor Authentication." Check "Request Security Code" to receive a text message with a login code to your account's phone number each time you sign up.
Under the hamburger menu in the mobile apps or in the top right of a web browser, click on "Settings"> "Security and Login" or go to https: / /www.facebook.com/ Settings? Tab = security. In the "Using Two-Factor Authentication" section, you can register your phone number to receive a code each time you log in, or have Facebook send a push notification to your phone to authorize or deny the sign-in attempt.  Here you can also set up a security key to log in via USB or NFC, or generate a recovery code in advance if you travel abroad where you do not have a mobile service.
If you do not want to use it 2FA Each time you log in from the same device (for example, from your personal laptop or phone), you can also set up your trusted devices in the Authorized Logins menu. In this way, you can grant access to the 2FA device bypass that is currently registered with your Facebook account.
Click on your profile avatar in the mobile Twitter app or browser version and look for the Settings & Privacy menu. Under "Account"> "Security" (or https://twitter.com/settings/account as a shortcut), you can switch to "Registration confirmation" to turn Twitter into a text for your telephone number.
Like any of the other services listed above, you can generate a backup code that you can use while traveling without Internet or cellular services, or even create a temporary app password that allows you to sign in from other devices. The temporary password expires one hour after its generation.
Go to the Amazon homepage and log in. On your account home page, search for "Sign In & Security" and click "Edit" under "Advanced Security Settings," click "Getting Started," and Amazon will guide you through registering your phone number. Alternatively, you can use your preferred authentication app by syncing it with a QR code.
After verification, you can select trusted devices to bypass 2FA or generate login code through a mobile app.
The easiest way to enable 2FA for your Google Account (for example, Gmail, YouTube, Gmail). or Google Maps) by going to the main 2FA homepage and clicking Get started. You'll be asked to sign in and enter a phone number before choosing whether to receive verification codes by text message or phone call. Like Facebook, you can also use "prompts" that allow you to simply click "Yes" or "No" during a login attempt or generate a security key with a USB key.
Here you can also generate backup codes for offline access. Google generates 10 each and they are each designed for single use. If you've used one successfully, swipe it out as it stops working.
On the main page of the app, tap the gear icon and look for "My Account," followed by "Login Confirmation." Select SMS to get a code each time you sign in. Once 2FA has been activated You can add trusted devices or request a recovery code in your Snapchat account if you plan to be anywhere without a mobile service.
To enable 2FA, you must access the Account Settings page. 1) Click on your username in the upper left corner to open a drop-down menu> "Profile & Account"> Click the gear icon, 2) In the chat window, click on your own username and select "Open account settings" or 3) and go to my.slack.com/account/settings. The second option under your username should be the activation of 2FA.
If you have more than one email address, you may need to select a default address before starting to choose whether to receive a passcode by text message through an Authenticator app. More at the end of this article. After you confirm your account with a six-digit code, 2FA will activate.
Log in to your Microsoft account and find the Security Settings menu. Select the setup of 2FA, and your phone number will guide you through each step, similar to the other services described above. If you do not have a cell service, click App Passwords to generate a one-time password for sign-in.
On your Dropbox homepage, click your profile avatar on the web and search for "Settings." > "Security". Scroll down a bit to find "2-step verification." There you will see the status of your 2FA. Click here to enable the feature and enter your phone number to confirm.
Open WhatsApp and enter the settings menu. Under Account, select 2-Step Verification and click Enable. You can enter your phone number just like everyone else on this list, or you can enter your email address as an alternate location for the verification code.
Mapping an email address to your WhatsApp account is important because the service does not allow you to confirm it yourself if you last used WhatsApp within seven days and forgot your PIN. So, if you can not wait a week to confirm for any reason (lost phone, your PIN can not remember), it's helpful to have an email to sign in or disable 2FA. In the same way: Be careful about emails that ask you to turn off 2FA if you have not requested it yourself.
Click the gear icon in the main dashboard and look for "Profile and Settings." You should not explicitly refer to the feature as "Two-Factor Authentication." So you have to search for "security key". Click here to set the 2FA code by entering your phone number, entering the SMS code and proceeding as usual.
If you lost your phone, changed the phone number, or you want to revoke the permission rights, return to this menu in the steps described above to make adjustments.
Some of the hacker attacks As these are the news of late, it's a good idea to add 2-step verification to your Nest Smart Home system.
Nest initially suggests that you use the latest version of the app on all your devices. Then, on the home screen, go to Settings / Account / Manage Account / Account Security and select 2-Step Verification. Turn the switch to On. In a series of prompts, you will be asked for your password, phone number, and the verification code that will be sent to your phone.
Keep in mind that all your devices will be automatically signed out, so you'll need to sign in again with 2-step verification.
One more tip: If not all of your family members have their own credentials but you have already used them, it's a good idea to set them up with separate credentials through the family accounts. If you try to sign in with 2-step verification, the required code will be sent to your phone, not yours.
For anything else that is not listed here, we recommend using Authenticator apps to keep track of verification codes so that you can get them without a mobile service. This is useful if you are traveling abroad and only have internet access. Popular options are Authy, Google Authenticator or HDE OTP (iOS only). These apps use essentially the same process when you add a new account: Scan a QR code associated with your account and store it in the app. The next time you need to sign in, just open your app to find the six-digit code needed to overcome security.
These additional steps are great for adding a security level to all your accounts. Remember, however, that you should do so. Change and update your passwords regularly, even if 2FA is enabled to stay in top condition.
