Explanation:

To keep passwords secure, we analyze each option:

• "Never be left out in the open" (e.g., not exposing password - related info) is also a valid security measure.
• "Always adopt long passphrases" is beneficial as longer passphrases are harder to crack. Since all these practices contribute to password security, the correct option is "All of the above".
