Google Authenticator, released in 2010, is one of the most popular applications two-factor identity (2FA). Specifically, it is used by millions of users for authentication of links across various sites websites and services. However, it has some disadvantages that must be taken into account.
Initially, it works on only a few platforms and specifically on Android, iOS and Blackberry. Another disadvantage is that users have to configure it separately on each device they use. This is not a big disadvantage for those who do not particularly use their smartphone, but for those who do smartphone has become an "extension of their hand", can be a serious disadvantage because they have to have the device near them. Another downside, which is quite important, is that every time a user changes phone, they have to open and close the entire application and synchronize all accounts from the beginning. This is very tedious, so turning off 2FA might be a good choice. Another disadvantage of Google Authenticator is that there is no password or biometric lock in the application. And this ease of access to the application seems to allow any malware steal 2FA codes directly from Google Authenticator. This is another reason why users should stop using this application.
So there is a need to find a new service out of the thousands available that performs better than Google Authenticator. The managers passwords 1Password and LastPass have built-in authentication applications, but there is also the application Authy. It is an application that is fast and easy to use and set up, runs on multiple devices and platforms, allows users to back up, and its site has a wealth of information on how to back up accounts using 2FA.
Some users argue that the benefits of removal from Google Authenticator far outweigh the disadvantages. Therefore, if one uses Google Authenticator, one can take a taste of some of the alternatives offered and consider all the above information the next time a smartphone is to be changed.
