WhatsApp is today making its new two-step verification feature available to all.

Once enabled, WhatsApp will require you to enter a six-digit passcode when you attempt to verify your phone number.

If you’re an Apple ID owner, you know that two-step verification is the best way to make sure that only you have access to your personal credit card details along with your app, music, and video purchases.

Until a couple of weeks ago, Amazon–another company that probably has private financial information from you–didn’t have a way to do the same thing. That way, even if someone figures out your password, they’ll only have half the info needed to make changes to or access your account.

Now that the Seattle-based books-and-everything-else company allows for it, it’s time to zip up your personal details. Here’s how.

Worried about the security of your Dropbox files, even if you use two-step verification? Dropbox has your back now with a new USB key-based system to ensure that you are the only one able to access your files in the Dropbox cloud.

“Today,” Dropbox writes on its website, “we’re adding Universal 2nd Factor (U2F) security keys as an additional method for two-step verification, giving you stronger authentication protection.”

If you make something private, obviously you want it to stay that way. But with hackers trying to get at your data, you need to be prepared. Following the recent iCloud hacking that leaked tons of private celebrity photos, there’s a renewed focus on security.

In today’s video, we show you how to enable two-step verification on all your Apple devices so you’ll have a better chance of keeping everything that’s near and dear to you private and secure.

Today Apple rolled out two-step verification for Apple ID accounts in 48 new countries. With the addition of countries like China, Japan, India, and France, two-step verification for Apple IDs is now supported in a total of 59 countries. Only 11 countries offered the extra security measure until today.

Apple began rolling out its two-step verification system for your Apple ID last year, adding an extra layer of protection for users. Now it is making the security feature available in more countries — including Canada, France, Germany, Japan, Italy, and Spain.

The concept of the two-step verification system, for those unfamiliar with it, is to make you enter a code (sent to a single trusted device) each time you make changes to your account, or make a new iTunes or App Store purchase using a new device.

Evernote announced Monday the availability of Two-Step Verification for all its users, increasing security for everyone, instead of just the premium members.

In a blog post, Evernote’s Andrew Sinkov said that the software company values its users’ data security. The feature was introduced with a few other security measures last month, including Access History and Authorized Applications, but was only available for Evernote Premium and Evernote Business users.

These extra security features are now available to all Evernote users.
