- What does two-factor authentication consist of? How does it prevent passwords from being stolen?Authentication using several factors defies my little knowledge of the subject. In what ways does it help to keep passwords safe, and how does it do this?Why do different methods of authentication each have their own set of benefits and drawbacks when it comes to security?
- An authentication system that uses challenges and responses should be described in detail. What makes it more safe than a system that relies on passwords?To what extent do different forms of authentication improve or compromise security?My understanding of multifactor authentication is limited. What kind of security does it provide for passwords?
- I'm perplexed by the idea of two-factor authentication. To what degree does it contribute to password security?Do several methods of authentication have any negative effects? What precisely does it do to assist protect compromised accounts from being attacked again?The notion of challenge–response authentication must be understood. In what way is it more secure than a password-based system?
