Two-factor authentication (2FA) is one of the most important measures that crypto and BTC owners can take to protect their exchange accounts and other assets from hackers. As a result, it has become a widely adopted security feature across various cryptocurrency platforms.

Among the various 2FA methods, Google Authenticator is the most widely used app by crypto users. It adds an additional layer of security to exchange accounts by requiring a secondary verification step during login. In addition to entering a password, users must enter a six-digit code generated by the Google Authenticator app installed on their phone.
Recently, Google released version 4.0 for iOS and Android, which includes cloud syncing. This new feature enables crypto and BTC users to synchronize Authenticator-generated verification codes with all Google accounts and devices, allowing them to retrieve verification codes even when the device is lost. The one-time codes are stored in the user’s Google account, which means they are no longer dependent on the device.
Google introduced this feature to simplify the process of signing in with Google Authenticator, which was first launched in 2012. Google received feedback from users regarding the complexity of dealing with lost or stolen devices that had Google Authenticator installed.
Users who lost their device could not log in to any service they had set up 2FA for with Authenticator. Only a backup code created when the app was installed could restore all login codes to a new Google Authenticator app running on a new device.
With the 4.0 update, Google introduces a more simplified solution to this problem: “With this update, we’re rolling out a solution to this problem, making one-time codes more durable by storing them safely in users’ Google Account. This change means users are better protected from lockout, and that services can rely on users retaining access, increasing both convenience and security.”
However, the blockchain security firm SlowMist warns that this new feature comes with greater risk. If a user loses access to their email account, for example, due to a hack, all access protected by Google Authenticator is at risk, according to SlowMist.
The new cloud syncing feature enables the retrieval of verification codes from any device, as long as the user has access to their Google account. This means that if an attacker gains access to the user’s email account, they may be able to obtain the verification codes and bypass the 2FA protection.
SlowMist recommends that crypto owners think twice before activating the new feature or sticking with the old backup solution. Users should be aware of the relevant risks and take steps to secure their email accounts, such as enabling two-factor authentication or using a strong and unique password.
It is important to note that 2FA is not a foolproof security measure. It is a layer of protection that can make it harder for attackers to gain access to your accounts. However, it is still possible for attackers to bypass 2FA, especially if they are highly skilled and determined.
Crypto owners should always take additional steps to secure their accounts, such as using strong passwords, enabling account alerts, monitoring their accounts regularly, and keeping their software up to date.
Moreover, it is important to use 2FA on all online accounts, not just crypto exchanges. This includes email, social media, and other financial accounts. By implementing 2FA, users can significantly reduce the risk of unauthorized access to their accounts.
So, What Should Crypto and BTC Owners Do?
While the cloud syncing feature of Google Authenticator 4.0 seems convenient, it’s not without its risks. Therefore, it’s important for crypto owners to weigh the benefits and risks before they activate the feature or continue using the old back-up solution.
One option is to use an alternative 2FA app that doesn’t offer cloud syncing. For example, there are apps like Authy, which encrypts your 2FA keys and stores them in the cloud, but only after the user has created a password and a backup password. Another alternative is to use hardware-based 2FA solutions like YubiKey, which generate 2FA codes on the device itself and don’t rely on the cloud or any other online service.
While these alternatives can be more secure, they can also be less convenient for some users. For instance, using hardware-based 2FA solutions can require carrying a physical device with you, which can be cumbersome. Meanwhile, using an alternative 2FA app may mean that users need to set up new codes for all their accounts.
Ultimately, the decision of whether to use Google Authenticator or an alternative 2FA app or solution comes down to a user’s individual preferences and risk tolerance. Crypto owners should evaluate the benefits and risks of each option and choose the one that makes the most sense for their needs.
In addition to using 2FA, crypto owners should also take other steps to protect their accounts from hackers. For example, they should enable multi-factor authentication (MFA) on their email accounts and use strong, unique passwords for all their accounts. They should also be careful about clicking on links in emails or text messages and only download software and apps from reputable sources.
It’s important to remember that cybercriminals are always finding new ways to compromise accounts and steal cryptocurrencies. Therefore, crypto owners should remain vigilant and take proactive steps to protect their assets. This includes staying up-to-date on the latest security best practices and being willing to make changes to their security protocols as needed.
In conclusion, while the new cloud syncing feature in Google Authenticator 4.0 may be more convenient, it’s important for crypto owners to weigh the benefits and risks before they activate the feature or continue using the old back-up solution.
Ultimately, the decision of which 2FA solution to use comes down to a user’s individual preferences and risk tolerance. However, no matter what solution they choose, crypto owners should take other steps to protect their accounts from hackers and remain vigilant in the face of evolving cyber threats.
