Two-factor authentication, abbreviated as 2FA, is also called two-factor verification, two-factor authentication, two-factor authentication, and 2-Step Verification. It is a special case of multi-factor authentication. It uses two different elements to randomly generate a verification code based on time for verification with the server to confirm the user's identity.
There are many free two-step verification tools on the market, and each tool is roughly the same, but there are also some differences. Some people may pay more attention to security when choosing a two-step verification tool, and think that those two-step verification software with synchronization have the risk of leakage; some people pay more attention to multi-device synchronization, because once the phone is lost or damaged, the two-step verification tool cannot recover the data, which will bring disastrous consequences.The article originates fromSinsTu NI-https://www.sinstu.com/archives/140.html
