Authy was recently contacted by Decryptionarya cryptocurrency and blockchain dictionary, with concerns about security vulnerabilities of using SMS for two-factor authentication 2FA and questions about how SMS is used in conjunction with the Authy 2FA apps.

These are great questions. There has been an increase in phone porting attacks sometimes known as SIM swapping. Phone porting is where cybercriminals trick your phone company into swapping your phone number to a different device and SIM card. Typically, this is done when an attacker already has your username and password and also needs to get the two-factor authentication 2FA text message as part of an account takeover. As such, the security industry and various media have been advising that users avoid using SMS for 2FA, and instead use apps on your phone like our Authy app which generate the same security code without the need for it to be sent via SMS.

First things first, SMS is not going away. Since almost every online user has an SMS capable device these days, and practically the entire world is texting, there is no learning curve per se. And if a device is not SMS capable, two-factor authentication via a voice call covers almost everyone else. But hijacking SMS is not as easy as other forms of attack.

But convincing multiple wireless providers to make changes to hundreds or thousands of customers phone plans takes a lot more effort and is much harder. If you have a smartphone or other mobile device, you can avoid using SMS and voice calls to get your 2FA code by downloading and installing one of many popular two-factor authentication apps directly to your device.

This is a much more secure method for your 2FA login. The data needed to generate those codes remains on your physical device, not within the SIM card. The first time you install Authy, we need to verify you and ensure that you have access to the phone number you claim to own. At this stage you have an important decision to make: do you keep all of your 2FA tokens on a single device, or back them up to the cloud?

Just ask anyone who lost access to their Google Authenticator accounts. This is why Authy allows you to backup your 2FA tokens to our secure cloud storage — accessible to only you so that you can always reinstate your accounts when you replace a lost, stolen or out-dated device. When you backup 2FA tokens to the cloud, we ask you to set a backup password, and we use this password to encrypt your data and then sync it to our cloud service.

Next, we highly recommend installing Authy on another device. Note: if you only have one mobile device, you might want to also download our browser-agnostic Authy Desktop app. This is a significantly more secure method of verification, because we check the new device against an existing device we already trust.

SMS is still an option at this point, and this is where the vulnerability of SMS once again causes a problem, but there is a simple way to protect yourself further. Now that you have two or more Authy apps installed on separate devices.

We highly recommend opening the Authy app, going into Settings, and switching off the multi-device option see below.Two-factor authentication is an essential security measure that uses your phone to help prevent unauthorized access to your account.

There are many ways to prevent this problem from happening, however. For easy access, here are a few links to where you can change your two-factor settings if you already have it enabled for some common services or learn how to do so. The process differs from service to service, but the basic principle is the same.

Simply activate your new phone and the codes will come to your phone number. Write down your backup codes. You can then set up a new authenticator, likely generate new backup codes, and be as secure as ever before. You should definitely print them or or write them down and keep them in a place where you can find them. Ideally, they would be separate from your phone, perhaps in a fireproof box or safe with other important paper documents.

For example, Google offers ten backup codes. This means that even if someone finds your backup codes and uses them to access your account, it would be difficult for them to do so undetected. Just sync the new device and deauthorize the old one.

Then, follow these steps to synchronize Authy to a second device:. While some authentication methods require an app, nearly all at least offer the use of an SMS code as a backup option. The downside? Of course, an attacker will also need your password to do anything with a specific account, but text-based authentication remains a less-secure method than two-factor authentication, since that requires them to have physical access to your authenticator device in order to break into your accounts.

While you have several ways to prepare for the worst, stuff happens. Your phone fell down a well, you lost your sticky note with the backup codes, and today just happened to be the day your Google account asked you to re-verify. Bad luck. The bad news is, an account recovery process can often take several business days to fix, assuming the company can do it. Other companies such as Discord will tell you that if the backup options fail, they will be unable to provide you with access to your account.

However, in the event the worst happens, here are some links with information on how or if you can get access to your account back for various services:. The A.

Some feedback from our millions of users First tweet from my new iPhone X! Powered by Twilio Toggle.Think about the last time you called a Customer Service agent for your bank, cable or telephone service. Does the process typically go smoothly? Or is it something you dread?

Usually, the need to place a call only occurs when something is wrong you rarely call into Customer Support to praise them. And the frustration gets amplified by a long, complicated and automated combination of fixed-voice menus—often referred to as a phone-tree—that a caller has to navigate just to speak to an actual person. Conversely, what is super frustrating is that the questions asked by Customer Care agents are rarely secure. To top it off, this archaic process often requires already upset customers to hang up, retrieve information from old emails or bills, and call back, only to repeat the process all over again most likely with a different agent.

And since keeping an agent on the line blocks them from attending to other calls and makes the call more costly, many customers request that an agent stays on the line while they look for the odd bit of information that will identify them. Revenge is sweet. I know this because I worked as a customer care agent early in my career. For many customer care agents, this is an issue encountered at least once per shift.

Sorry but there is already a request to change that number.One of the main reasons Authy was able to top our list of the best two-factor authentications apps was its ability to transfer access to a new device. This feature ensures that whenever you get a new phone, you don't lose all your tokens.

However, if the process is done incorrectly, you can leave your account vulnerable. With Authy, you don't have to worry about losing access to important online accounts just because your phone gets lost, broken, or stolen. You can either transfer the access from one phone to another or keep your account accessible on two devices, so it is even easier to access your tokens.

Both options have similar procedures, only differing by one step, which I'll outline below. Obviously, you need Authy on the new phone to get started.

On your new phone, when you open Authy, a page will appear asking for your phone number. Authy uses your phone number as a way to store your account, making it easier to retrieve. Once inputted, a new prompt will appear asking you to verify your account in one of three ways: using your old device, by phone, or by SMS.

Since using an existing phone is both the easiest and safest method, we will start with that one. Select "Use existing device" to reveal a new prompt asking you to wait for approval. On your old phone, a notification will appear asking you to approve the new device. Input the text and select "OK," and after a few seconds, your new device will have access to your account. If you don't have the old phone because it's broken or stolenyou can still use "SMS" or "Phone call" to input the code. Choosing "SMS" will have the system send you a text message with your code, which you input in the prompted area.

For "Phone call," Authy will call your phone number and read off the code you need to enter. Once the code is correctly entered, you can see all your accounts. You may have noticed that all your accounts have a small red padlock next to their name.
