The Truth about 2FA (Two-Factor Authentication)

It’s everywhere these days: 2FA (two-factor authentication).

More and more, you must use something more than just a password to secure your online accounts.

Some sites, like PayPal, are apparently requiring 2FA for everyone.

So, what types of 2FA are there? Do you have to use a smartphone? Is there an alternative to SMS-based 2FA? And most importantly, is it that much safer?

Finally, I reveal the other reason why everyone is pushing 2FA so much – and it doesn’t have anything to do with your security or privacy!

Two-Factor Authentication without SMS or a smartphone

These days, 2FA (Two-Factor Authentication) is all the rage.

Instead of securing your account with only a password, you have to enter a password and a secret code… But where to get this code?

The simple way is via an SMS to your phone, which means you also must provide your cell phone number to various sites.

Smartphones also have authentication apps, but the problem is that you must still have your smartphone on and connected to the cell network in order to log in to a simple web site!

That’s not very convenient…
