Why is it recommended to disable password authentication and use only SSH keys on a Raspberry Pi?
ABecause passwords are faster to crack than keys
BBecause SSH keys provide stronger security than passwords
CBecause SSH keys allow anyone to connect without restrictions
DBecause disabling passwords saves system resources
Step-by-Step Solution
Solution:

  1. Step 1: Understand SSH key vs password security

    SSH keys use cryptography making them much harder to crack than passwords.

  2. Step 2: Clarify misconceptions

    Keys do not allow unrestricted access; disabling passwords does not save resources significantly.

  3. Final Answer:

    Because SSH keys provide stronger security than passwords -> Option B

  4. Quick Check:

    SSH keys = stronger security than passwords [OK]
Quick Trick: SSH keys are more secure than passwords [OK]
Common Mistakes:
  • Thinking keys allow unrestricted access
  • Believing passwords are equally secure
  • Assuming resource saving is main reason
