User-friendly security for the moments people are most likely to get stuck.

MB Usable Security is a usable security research and product studio. We study and build tools for login, authentication, account access, and identity workflows.

Our goal is simple: Help organizations create security that people can actually use.

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.

Where security usually breaks down

Three areas where MB Usable Security researches, designs, and builds — always with the person on the other end of the screen in mind.

Where We Focus

Login & Authentication

Sign-in • Password reset • MFA • Recovery • Lockouts

Safer Access Patterns

Identity • Biometrics • Device trust • Adaptive auth – Human review

Reducing Workarounds

Password reuse • Written passwords
Credential sharing • Disabled protection • Confusion

The Lockline

An exclusive 24/7 login concierge membership.

Built for professionals supporting aging parents, grandparents, aunts, uncles, or other older loved ones. When an older loved one gets locked out, receives an alarming account text, or is unsure about a password reset email, the burden often falls on the busiest person in the family.

The Lockline gives families a private support path for serious login and account-safety moments.

So your loved one is not alone. And every account issue does not have to become your emergency.

  • Private support line

A dedicated path for login and account-safety moments — not a call center queue.


  • 24/7 availability

Lockouts and alarming texts don’t= wait for business hours, and neither do we.


  • Built for the busiest person in the family

So one account issue doesn’t have to become your emergency.


  • Peace of mind for loved ones

A calm, trusted place to turn when something feels off online.
