[&] How does token-based authentication typically enhance user experience?
- By storing credentials in plaintext for easier access
- By eliminating the need to re-enter credentials multiple times -- Correct
- By providing a more intricate password setup
- By requiring manual re-entry of user information with each request

[&] Which authentication mechanism uses protocols like SAML or OAuth?
- Biometric authentication
- Token-based authentication
- Multi-factor authentication
- Single sign-on (SSO) -- Correct

[&] What is the primary function of an authentication mechanism?
- To verify the identity of a user or system -- Correct
- To optimize network bandwidth usage
- To enhance user interface design
- To accelerate data processing

[&] In what way does a one-time password (OTP) add security compared to a standard password?
- It is only valid for a single login session -- Correct
- It is less complex than regular passwords
- It replaces the need for a password
- It is permanent and never changes

[&] What is the primary advantage of single sign-on (SSO) authentication?
- It utilizes complex encryption algorithms for each login
- Users can access multiple applications without re-entering credentials -- Correct
- It limits access to a single system
- It requires users to change their passwords frequently

[&] Which of the following best describes two-factor authentication?
