How to add an extra layer of security to your online accounts

Two-factor authentication adds a layer of protection to the standard password method of online identification. You simply add another identification feature alongside your password and it’s usually a phone number. It’s free and quick and easy to do. Critics point out that because you usually have to use your phone number it’s just one more bit of information you’re handing over to a third party. This is true, but as hacks and database breaches become increasingly common it’s also one of the most practical and simple protection options available.

If you have a PayPal account and ever take a peek into the dark web you might find yourself a little horrified. Alongside drugs, guns, credit and debit cards for sale you’ll often find PayPal accounts.
The prices vary according to how much is in the account. You have to pay a little more for a PayPal account with $10,000 in it than you would for an account with $2,000 or $5,000. Of course the sellers kindly offer a ‘How to’ guide too so buyers’ can quietly extract the money without the legitimate owner knowing anything about it.
But why are PayPal accounts so popular? Well, it’s not just PayPal but any account of value that is poorly protected. If a hacker gets an account address all they need to do is crack the password. Given that most people use simple passwords, using software specifically designed for password cracking is an easy task.
However, if you introduce two-factor authentication into your accounts it becomes much more difficult, by several orders of magnitude, to access the account. The password acts as the first line of defence – so toughen it up – and the second factor adds another barrier by introducing what is usually a phone number.

Identity Protection

Two-factor security isn’t infallible – but it is a good step towards protecting against account compromises. A case in point is the 1 billion account Yahoo breach
If a Yahoo user had a strong password in place bolstered with two-factor authentication the likelihood of hackers being able to breach the account may have been severely diminished if Yahoo had encrypted the two-factor steps.
BullGuard Premium Protection offers the best safeguards against these types of account breaches. It includes identity theft protection that alerts you immediately if any of your personal details are discovered online.
For instance, when a company is breached, emails, passwords, bank details, card numbers and so on are typically sold on dark web forums and web sites. BPP trawls the internet 24/7 and using a special algorithm searches for the personal information you want to protect. It’s the best way of safeguarding your sensitive data because if it is stolen as soon as it appears for sale, or someone tries to use it, you know about it and can take steps to defend yourself against loss.
