Google Authenticator is the most reliable two-factor authentication method
The SIGEN cryptoexchange offers users 3 forms of two-factor authentication: email, Google Authenticator, and a table of printed paper codes.
Google Authenticator (GA) may be called the most reliable of these methods.
Why is Google Authenticator best?
– With email confirmation, users are still vulnerable. For example, if an email account is not protected by a strong password, hackers may access it and thereby be able to break into your SIGEN account. Additionally, many people use the same password on multiple websites. GA confirmation eliminates this problem. Google Authenticator generates a new code every 30 seconds. Moreover, you have the device with the GA program on your person. Hackers don’t have enough time to read, calculate, and enter the required code.
– Confirmation using a table of printed paper codes may have risks. For example, you might lose the printed sheet of codes, or a malicious party might discover the codes and exploit them. Once again, GA confirmation eliminates this problem. Of course, a would-be attacker near you could secretly observe the genearted code, but, as we already mentioned above, he or she would not have enough time. Suppose an attacker knows your username and password and has secretly seen your code. He is unlikely to have enough time to get to his device and enter all the required information, because the code he lifted will become invalid after 30 seconds. And he would have to remember the code correctly. Furthermore, it is not so convenient for users to hunt to find the required code on a sheet of paper and constantly safeguard it.
If you lose access to the device with GA and cannot get into your account, know that each account on the platform also has a Security Code that you can use to change the 2FA method, if necessary.
