Why is SSH key authentication considered more secure than password authentication on a Raspberry Pi?

hard🧠 Conceptual Q10 of 15
Raspberry Pi - Security and Deployment
Why is SSH key authentication considered more secure than password authentication on a Raspberry Pi?
ABecause SSH keys require no configuration on the client side
BBecause passwords are always stored in plain text on the Raspberry Pi
CBecause private keys are cryptographically complex and not transmitted over the network
DBecause password authentication uses stronger encryption algorithms
Step-by-Step Solution
Solution:

  1. Step 1: Understand SSH key authentication

    SSH keys use asymmetric cryptography; private keys never leave the client.

  2. Step 2: Compare with passwords

    Passwords can be guessed or intercepted; keys are more complex and secure.

  3. Final Answer:

    A -> Option C

  4. Quick Check:

    Private keys stay local, enhancing security [OK]
Quick Trick: Private keys stay local; passwords can be intercepted [OK]
Common Mistakes:
MISTAKES
  • Believing passwords are stored in plain text
  • Thinking SSH keys need no client setup
  • Assuming password encryption is stronger
