Q:

What is two-factor authentication and how it can be implemented for public websites in Cyber Security?

Answer 1

• Tw0-factor authentication is also referred to as dual-factor authentication or two-step verification where the user provides two authentication factors for protecting both user credentials and resources while accessing. 
• The two-factor authentication can be implemented on public websites such as Twitter, Microsoft, LinkedIn, and more for enabling another protection on your already protected account with a password.
• For enabling this double factor authentication, you can easily go to settings and then manage security settings.
