Multi-factor authentication (MFA) is a security function that utilizes two blockchain networks to prevent attackers from easily gaining control over a user’s digital assets. MFA systems provide authentication to someone’s website or program by way of granting two independent log-in credentials.
In MFA systems, there are authentication tokens that are tasked to generate security codes for users. These codes are entered after the standard log-in process, which generally includes the inputting of usernames and passwords. This process ensures that even if a malicious actor gains access to a user’s credentials, the authentication token, which is kept in a blockchain platform, provides another layer of security.
The token also generates unique codes after each log-in session.
Apart from log-in security, there are also other processes that can be covered by MFA systems such as asset transfers and contract generation, among others. In these cases, a blockchain platform uses the authentication token to generate security codes. Then, another platform receives these codes to confirm a user’s identity to validate transactions.
