Not long ago, the sharing economy seemed to have taken over. Privacy was dead, and no one cared. But that was until revelations about government spying and worse came to light. Today, it seems just as many people are sharing...but many do so with more caution.

For some of us, the need to go truly anonymous is more important than ever. But when you go to a service online and its first three choices for signup are to use your existing Google, Facebook, or Twitter account credentials, it's almost like a subtle background check. Other services—like Google—expect you to share a phone number and older email address—to sign up (and if not at initial signup, you'll need them for activations later). So you're not exactly hiding your tracks.

What do you do if you want to set up an email address that is completely secret and nameless, with no obvious connection to you whatsoever, but you don't necessarily want the hassle of (or have the chops for) setting up your own servers?

This goes beyond just encrypting messages. Anyone can do that with a Web-based email like Gmail by using a browser extension like Secure Mail by Streak. For desktop email clients, GnuPG (Privacy Guard) or EnigMail is a must.

But those don't hide who sent the message.

Here are the services you should use to create that truly nameless, unidentifiable email address. But be sure to use your powers for good.

First Step: Browse Anonymously

Your Web browser is tracking you. It's that simple. Cookies, and now these unstoppable "super cookies" know where you've been and what you've done and they're willing to share. Sure, it's mostly about making sure you see targeted ads, but that's not much consolation for those looking to surf in private.

Your browser's incognito/private mode can only do so much—sites are still going to record your IP address, for example.

If you want to browse the Web anonymously (and use that private time to set up an email), you need the Tor Browser, a security-laden, Mozilla-based browser from the Tor Project. If you don't know about Tor, it's what used to be called The Onion Router, and it's all about keeping you anonymous by making all the traffic you send on the Internet jump through so many servers, people on the other end can't begin to know where you really are. It'll take longer to load a website than it would with Firefox or Chrome, but that's the price of vigilance.

The Tor Browser is available in 15 languages, for Windows, Mac OS, and Linux. It's self-contained and portable, meaning it'll run off a USB flash drive if you don't want to install it directly. And it's totally free. Even Facebook has a Tor-secure address to protect the location of users—and let users get access in places where the social network is illegal or blocked. Like China.

Don't get the impression that Tor is utterly perfect and will keep you 1,000 percent anonymous. Last year, the criminals behind the Silk Road, among others, tried that and failed. But it's a lot more secure than openly surfing. And it took law enforcement agencies with a lot of resources to get those bad guys.

Anonymous Email

You can set up a relatively anonymous Gmail account, you just have to lie like a bathroom rug. That means creating a full Google account, but not providing Google your real name, your real location, your real birthday, or anything else they can use when you sign up (while using the Tor Browser, naturally).

You will eventually have to provide Google some other identifying method of contact, such as a third-party email address or a phone number. With a phone, you could use a burner/temp number; use an app like Hushed or Burner or buy a pre-paid cell phone and lie through your teeth when asked for any personal info. (Just know that even the most "secure" burner has its limits when it comes to keeping you truly anonymous.)

As for that third-party email, there are anonymous email services you can use, so why use Gmail at all? The Electronic Frontier Foundation (EFF) says it's smart to use a different email provider from your personal account if you crave anonymity—that way you're less likely to get complacent and make a compromising mistake.

Note that you also should use an email service that supports secure sockets layer, or SSL, encryption. That's the basic encryption used on a Web connection to prevent casual snooping, like when you're shopping at Amazon. You'll know it's encrypted when you see HTTPS in the URL, instead of just HTTP. Or a lock symbol shows up on the address bar or status bar. The big three webmail providers (Gmail, Yahoo Mail, and Outlook.com) all support HTTPS. Get the HTTPS Everywhere extension for Firefox, Chrome, Opera, and on Android, to ensure that websites default to using the protocol.

That's great for Web surfing, but HTTPS isn't enough when emailing. You know that.

Pseudonyms in email (like anonguy55@gmail.com) definitely aren't enough, either. Just one log-in without using Tor means your real IP address is going to get recorded...and that's enough for you to be found (if the finder can get your provider to give up some records). That's how General Petraeus got nailed.

The point is, once you've gone this far, there's no reason go back. Use a truly anonymous Web-based mail service to send your messages. Here's some of the best.

Hushmail



Recommended by the EFF and others, Hushmail's entire claim to fame is that it's Web-based, easy to use, doesn't do advertising, and has built-in encryption between members. Of course, to get all that, you have to pay for it, starting at $34.99 per year for 1GB of online storage. (There's a free version with 25MB of storage, but you need to re-up your sign-in at least every three weeks.) Businesses can use it for $5.24 per user per month, and they get their own domain name (though then you need to obfuscate your info for the Whois database). There's a free trial so you can check out Hushmail for yourself.

Note that Hushmail has turned over records to the feds before, and its terms of service state you can't use it for "illegal activity," so they're not going to fight court orders. But at least they're honest about it up front.

Hide My Ass! Anonymous Email



Hide My Ass is a well-liked private virtual private network (VPN) service that makes it a breeze for users to access content blocked at their location, not to mention providing a much higher level of privacy (hence the name). Base price is $11.52 a month, but the price goes down if you pay for more months at a time.

An extra that comes with HMA is its Anonymous Email service—in fact, it's open to anyone, you don't need to pay for VPN service. You get an address @hmamail.com that can be set to last 24 hours, one week, one month, six months, or 12 month. There's a countdown clock to indicate just how long you have left when reading messages. At signup, it does ask for your existing email address, so HMA can send it a note when you get a message on the anonymous account, but it's not required. The interface won't win any awards—Hushmail's is infinitely nicer—but it gets the job done. (HMA also has iOS and Android apps that provide secure mobile connections, plus privatized SMS texts and chat services with other HMA users.

Guerrilla Mail



Guerilla Mail provides disposable, temporary email. Technically, the address will exist forever, and never be used again. Any messages received at the address, accessible at guerrillamail.com, only last one hour. You get a totally scrambled email address that's easily copied to the clipboard. There's an option to use your own domain name as well, but that's probably not keeping you under the radar. GuerrillaMail is the perfect way to create an email address to sign up for a different, more permanent-yet-anonymous email address. Or to send a quick, anonymous email instantly—no signup required. You can even attach a file if it's less than 150MB in size, or use it to send someone your excess bitcoins. Coupled with the Tor browser, you're practically invisible.

Mailinator



Mailinator's free, disposable email has a slick interface, but you probably don't even need it. Whenever you're asked for an email, just make up a name and stick @mailinator.com at the end. Then visit the site, enter the name, and you'll see if it's received any messages. No signup required, though you can sign in with a Google account.

Here's the problem. If someone else comes up with the same name, then you both get access to the messages received. There's no passwords. There's also no sending possible. Its FAQ states if you get an email from Mailinator, it's a guaranteed forgery. This one is for quick service signups only, and only with the most obfuscated, obscure name you can come up with.
