![]() Therefore, we recommend that you disable this option when you are not using it. This means that you can install Authy and log in only to retrieve codes when the option is enabled. To avoid SIM card swap attacks, Authy has a multi-device feature. You must know now that Authy uses the SIM card number to register the device on their servers. Hopefully the LastPass server will no longer be hacked. ![]() In this way, you are protected against SIM card swap attacks because the only way to access 2FA codes is to steal your device. Some users claim that it is more secure to keep everything locally and not to perform cloud backups. Unlike Authy, your account is linked to your LastPass account. Multifactor authentication does not work offline, which makes it redundant, in my opinion. You can then decide to store everything locally (encrypted) or keep everything online that will require an active Internet connection to connect. Basically, you must connect the Authenticator application with LastPass and enable the Multifactor option from the settings. LastPass provides a detailed tutorial on the procedure to follow. ![]() It also offers a password manager that will manage your passwords. When you enable the backup option, the codes are encrypted and stored on the LastPass servers. So be sure to keep a very safe and secure location. If you lose it, even Authy will not get it back for you. Nobody has access to this backup password. Before you can access the codes, you must decrypt them using the backup password that you created at the time of the backup. ![]() However, you must use the same phone number to log in and start the recovery process. After that, Authy will encrypt them on your device first, and then back up all the codes on its servers.Īnd if you lose your phone or it gets stolen? If you lose full access to your phone, you will need to download Authy on a new device. Of course, you can still activate it later from the application settings. Overall, both apps have an almost identical user interface and make it easy to add and read QR codes on the fly, but Authy does it better.Īuthy will ask you to enable the backup option when you scan a QR code for the first time. In addition, Authy supports list and grid views. LastPass Authenticator lacks this simple but useful feature, making the user interface less attractive and more difficult to navigate. However, this raises the question of switching SIM cards (more on this later).Īuthy extracts the logos from the most popular sites, making it easy to identify codes in a sea of text. This means that you need an active SIM card. It may seem strange to you that Authy asks for your mobile number when you launch the application for the first time. For me, scanning a QR is faster and easier. There is a plus sign to add a scan and add 2FA codes quickly, either by scanning the QR code or entering the key manually. As with most 2FA applications, the layout is quite simple. Surprisingly, Authy and LastPass Authenticator adopt a red theme. It's time to see which 2FA you should trust with your online world and why. LastPass is a popular password developer that has released a 2FA application that offers cloud backups and multi-device synchronization.
