What is usable security?

Usable security means user-friendly security. It means security that protects people without confusing them, locking them out, or pushing them into unsafe shortcuts.

When security is too hard, people find workarounds.

  • They write down passwords.
  • They reuse passwords.
  • They share credentials.
  • They turn off protections.
  • They click too quickly.
  • They ask someone else to handle the problem.

“Most of those workarounds are not signs of carelessness. They are signs that the system failed the user.”

User-friendly security reduces the need for dangerous workarounds.
