2 Factor Authentication

While many people might not yet know the term “two-factor authentication,” there is every chance that you have come across it when you want to check your email, or perhaps your bank statement on-line. Having a password alone unfortunately isn’t as secure as it used to be and if someone gets your password, they can access your account without any fuss. Even having a strong password doesn't completely protect you. Two-factor authentication can help solve this problem.

But what exactly is Two Factor Authentication (or 2FA)? Basically it requires not one but two pieces of privileged information before giving access to an online account. It works on the basis of “something you know and something you have”, ie when using your bank cash machine, you insert your bank card (something you have) and enter your passcode (something you know).

2FA can be a little time-consuming as most major sites and services offering 2FA do it as an optional security feature, so you’ll need to dig around in the security settings of each account to find it. Much also depends on your willingness to ensure a higher level of security as you’ll need to prove your identity every time you log into a protected account from a new device.

However, 2FA does make it much harder for hackers to gain control of your accounts. For example, a hacker trying to access your email account has your email address and even your password, however doesn't have the second element of the authentication process, which in most cases is a unique security code that's sent directly to your mobile phone via text messaging.

Most major services support two-factor authentication when you attempt to log into your account from a new machine:

Google/Gmail sends you a 6-digit code via text message. It also works with the Google Authenticator app for Android, iOS, and BlackBerry.

Apple sends you a 4-digit code via text message or Find My iPhone notifications when you try to log in from a new machine.

Facebook’s two-factor authentication is called "Login Approvals” and sends you a 6-digit code via text message. It also works with apps like Google Authenticator for Android, iOS and BlackBerry, as well as the "Code Generator" feature of the Facebook app.

Dropbox sends you a 6-digit code via text message, although it also works with Google Authenticator and a few other similar authentication apps.

Microsoft sends you a 7-digit code via text message or email. It also works with a number of authenticator apps. Windows Phone users can download Microsoft’s own authenticator app from the Windows Store.

Yahoo! Mail sends you a 6-digit code via text message when you attempt to log in from a new machine.

Yet More Scammers!!

unknownYou may think that the subject of this week’s blog is a bit of a cheat as I have previously written about it but phone scamming is once again on the increase and because it is such a heartless act, I would really like to remind people about it.
 
Phone scamming happens when a caller pretends to be a “technical support engineer” from either a Windows or Microsoft call centre, who has discovered problems or viruses on your computer. The caller will persuade you to give them access to your machine and once in, will use a common scare tactic of showing you lots of yellow and red exclamation marks and other scary looking error messages on the machine and claim that these are caused by viruses (which of course they are not, they are quite simply logged events such as your printer once having run out of paper or a web page you once tried to access was down).
 
The “engineer” will of course require immediate payment to clean up the “dangerously infected” computer and install “protection” software onto the system. In addition and unbeknownst to you, they are highly likely to install malware on your PC in order to obtain your online shopping or banking information, thus being able to steal money from your bank account.
 
Genuine computer companies will never, ever call you to report computer problems. So if someone claiming to be from Microsoft or Windows technical support calls you, we recommend the following:
 
Do not purchase any software or services.
Ask if there is a fee or subscription associated with the "service." If there is, hang up.
Take down the caller's information and immediately report it to your local authorities.
Never provide your credit card or financial information to someone claiming to be from “Microsoft tech support.”
 
If you’ve been victimised by a phone scammer:

 
Contact your credit card or bank Fraud Prevention Team to have the charges reversed and the account protected from future charges.
Change your computer password, along with the password of any online accounts that may have been provided to the scammer.
Update your security software and run a full security scan on your computer. You may also want to contact a local IT professional to have your computer checked for malware.

Please tell your friends and family about these scams. If more and more people are able to stop making it financially worth their while, then the scammers might stop bothering innocent computer users.
