2 factor authentication

With a two-factor authentication (2FA) set up in minutes, your accounts can be better protected against third-party access at Facebook, WhatsApp, Amazon & Co. We show you which popular providers support the system and how you can find the settings there. The protection of an online account via two-factor authentication (2FA) has long been possible with most services, but many users still forgo this elementary and reliable protection. Some do not know how to activate them, others save themselves the establishment of the access barrier for your convenience. We’ll show you how to protect your Facebook, WhatsApp, Amazon, Google, iOS, MacOS and many other services against unauthorized access in minutes using tow factor authentication.

A properly set-up two-factor authentication (2FA) also keeps your account from being accessed by someone else who guesses the usual combination of e-mail address and password, or by other means (theft, hack, etc.) gets. For access to a user account, you do not only need access data but access to a second device. This device – eg your smartphone – is sent with a code or a request, which must be confirmed separately by the user.


The world’s most popular social network Facebook hides the establishment of two-factor authentication (2FA) in the settings accessed through the Gamburger menu. Click on “Settings” and then “Security” or on this link, where you will find the appropriate area. Facebook requires your phone number to verify your access data, to which a code or push notification will be sent after a successful setup. Please note that Facebook could then match this number with other data (foreign address books, WhatsApp, and similar applications).


WhatsApp now also allows the 2FA setup in the settings of your account, where you click on “Two-step verification”. There you should enter an e-mail address, because WhatsApp locks your account after a seven-day non-usage or if you forget your assigned PIN. The required details for the unlocking of the access are then sent to the stored email address. Please note that attackers are increasingly using this system and are attempting to access your access data in deceptively genuine phishing e-mails.


A two-factor authentication (2FA) for PayPal and other services is particularly important because an attacker can use these services to deduct significant amounts of money from a linked bank account or a deposited credit card. The setup at PayPal is via the menu point “Profile & Settings”, there you orientate you direction “Security Key”. PayPal now sends an SMS with a code, which has to be entered into the corresponding input mask, with every account access to the stored mobile phone number.


An unauthorized access to the Microsoft account allows an attacker not only to access the Outlook emails or purchased licenses but also to access the data stored in the OneDrive cloud. This is especially problematic when a backup program for Windows or Android stores complete backups. The settings can be found under this link.


The same is true for Microsoft as for the Cloud storage Dropbox, this is about the protection of personal data in the files stored there. The corresponding device can be found under “Settings”, “Security”, “find” Two-Step Verification “.


With a two-factor authentication (2FA) for your Google account, you protect access to your Gmail as well as access to all other services such as YouTube, Play Store or Drive. Google offers several options, all of which can be accessed via a specially configured page.


The idea of a two-level access authorization should be known to many people at the latest when someone orders goods via Amazon on their behalf. As with all other services, the setup takes only a few minutes and can be done via the user account or via this direct link.


The Twitter platform, which is not necessarily popular in Germany, is also capable of two-factor authentication. Here, too, the necessary settings are hidden in the account or can be accessed via this direct link . Especially with Twitter, a particular problem becomes clear: providers such as Google, Facebook or even Twitter provide for other services so-called “social logins”. An unauthorized access to the respective account thus extends the access to many other services which are already linked to the account or the e-mail addresses stored there.

Apple iOS and macOS

IOS or the associated Apple ID can only be protected with versions of “9” and “El Capitan” with two-factor authentication. In previous iOS versions, the necessary settings are hidden under “Settings” »[Name]» “Password & Security” , in iOS version 10.2 under “iCloud” »” Apple ID “» “Password & Security” . With macOS, the path leads via iCloud “” “Apple ID” “” Password & Security “ .


The very popular Instagram, which has been very popular for some time, can also be secured, but the two-factor authentication can only be set up on a mobile basis despite the now possible desktop access. Via the hamburger menu in the app you get into your account, there you should find the appropriate setting.


The same is true for Snapchat, here you can go to “My Verification” “Login Verification”.Like many other services, Snapchat offers the addition of trusted devices or the generation of backup codes, which you should keep in a safe place and which can be used with a lack of access to the SMS-enabled device.


A two-factor authentication of course only works if the attack on the respective account is done without access to the device via which, for example, a code sent via SMS isreceived. A password or fingerprint is required for your smartphone. In addition, one should deal with the topic of backup codes in time or provide a working second mail address, in order not to exclude itself.
