Password managers: stop reusing passwords

Almost every data breach that hits a smaller company doesn't start with an advanced attack. It starts with a password that already leaked from a completely different service, and gets reused somewhere in your business.

Why reusing passwords is so dangerous

When a service (any service, a forum, an old webshop, a tool you stopped using years ago) gets hacked, usernames and passwords often end up online. Attackers then test the same combination against thousands of other services automatically. If the same password is used for email or a business system, it's only a matter of time.

What a password manager actually solves

A password manager, Bitwarden or 1Password for example, generates and stores a unique, long password for every service. You only need to remember one master password. No reuse, no sticky note under the keyboard.

How to roll it out without grinding to a halt

1. Choose a manager with team or business support, not just the personal version.
2. Start with the most critical accounts: email, finance systems, cloud services.
3. Swap in a generated, unique password each time you log into something over the next few weeks, not all at once.
4. Turn on multi-factor authentication (MFA) on the same accounts. It stops most attacks that a leaked password would otherwise get through.

A password manager is the single action that buys the most security per minute invested. If you only do one thing from this list, do this.
