Final answer:
To implement two-factor authentication on a website, follow these steps: choose a method, integrate it into the login process, and test it. Two-factor authentication adds an extra layer of security by requiring users to provide two pieces of evidence.
Step-by-step explanation:
To implement two-factor authentication on a website, you need to follow a few steps:
- Choose a two-factor authentication method, such as text message codes, email verification, or biometric data.
- Integrate the chosen method into your website's login process by adding the necessary code and APIs.
- Test the implementation to ensure that it's working correctly and providing the desired level of security.
Two-factor authentication adds an extra layer of security by requiring users to provide two pieces of evidence to prove their identity. This could be something they know (like a password) and something they have (like a verification code sent to their phone). It helps protect against unauthorized access, even if a password is compromised.
