Every year, the list of most common passwords makes its way around the internet, and every year, it’s just as concerning. People are still using “123456” and “password” like it’s 1999. Meanwhile, cybercriminals don’t need cutting-edge hacking tools when people hand them the keys.

Research shows that 40% of passwords used by corporate employees are identical to those used by everyday internet users. In other words, the same weak, overused passwords that people rely on for social media and shopping accounts are also protecting company data. That’s like locking the front door but leaving the windows wide open.

MSPs can only do so much to help protect businesses from cyberattacks. Employees play a major role in cybersecurity, and password security is often overlooked.

A strong password isn’t optional—it’s your first line of defense.

Just one weak password can unlock the door to data breaches, financial loss, and serious consequences. Don’t give attackers an easy way in.

Let’s talk about what makes a strong password, why password managers should be a standard business tool, and how companies can tighten security across the board.

The Password Security Checklist: Is Yours Strong Enough?

Most people assume their passwords are “good enough.” They aren’t. A secure password needs to be long, unpredictable, and unique. Here’s what that means:

• Length matters. A password should be at least 12–16 characters. Shorter passwords are easier to crack.
• Complexity counts. A mix of uppercase, lowercase, numbers, and symbols makes guessing harder.
• Predictability is a problem. Birthdays, pet names, and favorite sports teams are bad choices. If it’s easy to remember, it’s probably easy to guess.
• Recycling is risky. If the same password is used across multiple accounts, one leak puts everything at risk.
• Passphrases beat single words. A random string of words— “desk-lamp-marathon-cookie” —creates a long, strong password that’s easier to recall than a jumble of characters.

For businesses, these rules need to be more than guidelines. They should be enforced company-wide. Employees won’t take security seriously if the company doesn’t, either.

The Case for Password Managers

People are bad at passwords. They make them too simple, reuse them across sites, or forget them altogether. That’s why password managers exist—to eliminate the guesswork.

A password manager generates, stores, and auto-fills complex passwords so users don’t have to remember anything beyond a single master password. For businesses, this means employees aren’t using sticky notes, spreadsheets, or whatever their go-to easy-to-remember phrase is.

But convenience isn’t the only selling point. Password managers also:

• Stop password reuse. Employees no longer need to recycle the same login across multiple sites.
• Secure passwords with encryption. Even if a hacker gets into the system, the passwords remain protected.
• Work across devices. Whether an employee logs in from a laptop, phone, or tablet, passwords stay accessible but secure.
• Provide admin control. Businesses can set password policies, revoke access when employees leave, and monitor security risks.

The biggest reason people resist using a password manager is that they think it’s complicated. But resetting a dozen hacked accounts after a breach is a lot more complicated, and your MSP can help make adoption digestible for your team.

Add MFA Everywhere It’s Available

Even the strongest password isn’t enough on its own. Multi-factor authentication (MFA), sometimes called two-factor authentication (2FA), adds a critical second layer of defense. It’s one of the simplest and most effective ways to protect accounts from unauthorized access.

Whether it’s a mobile authentication app, biometric scan, or physical security key, MFA ensures that even if a password is stolen or cracked, it won’t be enough to break in.

If a service your business uses supports MFA, enable it—no exceptions. And require your team to do the same. MFA should be standard for every account that allows it.

Password-based authentication is gradually being replaced by more secure, user-friendly methods like passkeys and passwordless login systems. But until that transition is complete, businesses must follow password best practices—and pair them with MFA—wherever possible.

Passwords Won’t Be Around Forever—But They’re Not Gone Yet

The future of authentication is passwordless. Passkeys, hardware tokens, and biometrics are all gaining ground, and they offer more secure, user-friendly experiences. But until that future becomes the default, strong password practices still matter.

So take the checklist seriously. Use a password manager. Turn on MFA. And make sure your team isn’t the weak link in your security chain.
