Everything you need to know about atSigns (and more!)

atSign Essentials

What is an atSign?

An atSign is a handle (i.e. @alice) that functions as your address on all atPlatform-based apps. It uses end-to-end encryption to ensure that your data is 100% owned and controlled by you.

Soon, your connected devices will also have atSigns, allowing you to communicate with them directly and extend this control to the Internet of Things. 

Why should I have an atSign?

As we envision it, the new and improved Internet will be driven by the adoption of atSigns. An atSign is your unique address that will allow you to interact with atPlatform-based apps. These apps will range from health apps to GPS to contact/address book apps–you name it. Importantly, as more and more of the world becomes connected through IoT devices, atSigns will be the key to ensuring your data is safe. Imagine being able to control ALL of your data, whether that’s from your fitness tracker, your car, or your thermostat. No company can ever see your data without your express permission, and this is all powered by atSigns.

And remember, the early bird gets the worm! In fact, if you’d like to be @earlybird, it’s still available! Joking aside, registering your atSign ahead of the crowd means getting the atSign you want. Click here to register yours today!

How can I use my atSign?

Currently, you can use your atSign with apps that have been developed on the atPlatform. In fact, your atSign replaces the traditional username/password setup; instead of having to remember multiple usernames and passwords, you only need one atSign to engage with atPlatform apps.

To get started, activate your atSign by pairing it with any atPlatform app. (Find the full list here.) Once activated, your atSign will work with all existing and yet-to-be-released atPlatform apps.

In the future, you’ll be able to use your atSign to manage your connected devices, which will have atSigns of their own. Learn more, here.

If someone knows my atSign, can they see all my information?

Anyone who looks up your atSign can only view the information that you’ve made public through atWavi, an app that lets you set up and customize your public profile. You’ll have the freedom to adjust it as needed, and those changes will be viewable in a matter of seconds.

How much does an atSign cost?

We believe that everyone has a right to privacy, which is why we offer free, random(ish) atSigns with our atSign generator.

If you want to secure a more custom atSign, they are available for between $10 and $5,000 (or even more!), depending on your desired level of customization.

For example, multiple words (i.e. your first name and last name) will cost $100, single words will be $1,000 (because there are so few of these), and atSigns with three characters will cost $5,000. Of course, you cannot buy a trademarked name, since the rights belong to the owner of that trademark. And yes, you can customize with emojis!

Can I transfer/sell my atSign to someone else?

Yes! To transfer your atSign to someone else:

  1. Go to your dashboard.
  2. Select My atSigns.
  3. Click on the atSign you want to transfer, then click on “Manage”.
  4. You will see an option that says “Transfer”. Type in the email you want to transfer the atSign to. The new atSign owner will have 60 days to accept your transfer request.

We are currently working on a way to safely sell atSigns to others. At the moment, we recommend that you only sell atSigns to those that you trust.

What do I have to do to renew my atSign?

If you have a free atSign, you don’t need to worry about a thing.

If you have a paid atSign, you’ll need to renew it for $10 each year. (We don’t store payment details, so we’ll let you know when it’s time to renew your atSign.) Instead of letting an atSign sit and collect dust, we want atSigns not currently in use to be made available to others.

Will I be able to use my atSign with my current apps?

We expect that many of your current apps will transition over time, as more of their customers transition to the atPlatform and away from applications that store their data.

All about atApps & Keys

I'm trying to use an atApp but don't have an atSign. What should I do?

You can either (1) create a free or custom atSign at, or (2) create a free atSign directly through any atPlatform app.

How do I pair my atSign with an app for the first time?
  • Using your atSign, email, or mobile number, log into your dashboard.
  • In your dashboard, click on “My atSigns”.
  • Underneath the atSign you want to activate, click “Activate”. You will be presented with a loading screen. (If you have already activated your atSign, select “Click to Scan” instead.)
  • Once the QR code has loaded, open the app you want to pair your atSign with.
  • In the app, type in the atSign you want to pair.
  • Scan the QR code through the app, or save an image of the QR code and upload it to the app. (Check that you have allowed the app to access your camera. Otherwise, you will not be able to scan your QR code.)
  • Be sure to save your atSign’s key somewhere secure.

If your atSign has already been activated with another app, just upload your key to sign into the app.

What is a key and why does it matter?

Each atSign has a unique key that is used to verify whether you are the atSign’s rightful owner. After first activating an atSign, be sure to save its corresponding key in a secure location. You’ll need it to sign back into the app or use other apps on the atPlatform.

Where should I save my key?

We recommend saving your key in a secure location on your device, such as Google Drive or your iCloud files. 

For iOS: After pressing “Save”, a screen with different save options will appear. To save your key to your iCloud files, scroll down and select “Save to Files”. Next, select “iCloud Drive” and press “Save”. You can also save your key to a different location of your choice — but make sure it’s somewhere secure!

For Android: After pressing “Save”, a screen with different save options will appear. To save your key to your Google Drive, select “Save to Drive”. You will be given the option to change the document title but we recommend that you keep it as it is. Make sure the account selected is correct. To choose a specific folder in your drive, press “My Drive” under Folder, choose your preferred folder and then press select. Next, press “Save”.

By default, your saved key should be named in the following format: @[YOURATSIGN]_key.atKeys. You can rename, move, or make copies of your keys.

How do I find my key?

For iOS: Open the Files app on your phone to access your iCloud files. (If you don’t know where your Files app is, swipe left on your phone and search for “Files”.) In the Files app search bar, type in your atSign to find your key.

For Android: Open the Drive app on your phone. (If you don’t know where your Drive app is, swipe down on your phone and search for “Drive”.) In the Drive app search bar, type in your atSign to find your key. If you renamed your key, type in the new key name instead.

General FAQ

Why do you ask for my email/phone number when I make an atSign?

Your email or phone number is linked to your atSign to ensure that you are the only one who can activate, delete, or transfer your atSigns. This also lets us notify you when your atSigns are ready for renewal.

Note: We do not share your personal information or use it for financial gain.

How are atApps different from what is available today?

You’ll have total privacy and utmost control over your data while using an atApp. No one will ever spy on you or misuse your information. Since atApps use your atSign as a proxy for your digital identity, you won’t ever have to create a new username or password while using an atApp.

Will there be atApps for businesses and corporations?

Glad you asked! Many of our atApps can be used in a business context as well. For example, you can set up a page for your business with atWavi or use atmospherePro to transfer files from one business account to another.

How will I know when new apps are available?

When you first get your atSign, you’ll see a checkbox that gives us permission to notify you when we have new apps. Please make sure that box is checked if you want us to let you know about new apps.

Or, join our Discord to get updates on all things Atsign, including new atApp notifications.
