Reused passwords and shared credentials are among the most common causes of business security incidents. A password manager solves both problems — here's how they work and what to look for.
The credential problem in small businesses
Most small businesses have a credential problem they don't think about until it causes a breach. Employees reuse passwords across personal and business accounts. Team members share login credentials for business tools via email or text. The "master password list" lives in a spreadsheet in a shared folder. The office manager knows the passwords to everything — until they leave.
Credential-related attacks are consistently among the most common causes of business account compromise. Data breaches from consumer services (LinkedIn, Dropbox, various retailers) expose billions of username/password combinations that attackers test against business applications. If an employee uses the same password for their personal accounts and their work email, a breach of any consumer service creates exposure for your business.
A password manager solves three distinct problems: it generates strong, unique passwords so credentials aren't reused; it stores and autofills those credentials securely; and it provides a structured way for teams to share credentials without passing them through insecure channels.
How business password managers work
A business password manager is a secure vault that stores all your team's credentials in encrypted form. Each user has their own account and private vault, and there are shared vaults or collections for credentials that multiple people need access to.
The vault is protected by a master password (and typically MFA) — but the master password never leaves your device. The password manager uses it to decrypt your vault locally, meaning the vendor never has access to your actual passwords. This architecture is the reason that breaches of password manager companies (which have occurred) don't expose user credentials.
For teams, business password managers add administrative controls: IT can provision and deprovision access, see what credentials employees have access to, enforce security policies (minimum password strength, MFA requirements), and transfer credential access when someone leaves — without having to know the individual passwords.
The business case for shared vaults
One of the most underappreciated features of business password managers is structured credential sharing. Every business has credentials that multiple people need: social media accounts, shared email addresses, vendor portals that don't support individual logins, Wi-Fi passwords, shared subscription services.
Without a password manager, these shared credentials exist in Slack messages, sticky notes, and that spreadsheet. When an employee leaves, you have no reliable way to audit what credentials they had access to.
With a business password manager, shared credentials live in a shared vault with access controls. You can grant and revoke access granularly — an employee can access the credentials they need for their role without being able to export or share them outside the vault. When they leave, you remove their access in one place.
Which password manager to choose
1Password Teams/Business is our most common recommendation for small businesses. It has excellent usability, strong security architecture, and a per-user team model that includes shared vaults, admin controls, and integration with Microsoft Entra ID and other identity providers for single sign-on. Cost is approximately $7–8 per user per month.
Bitwarden for Business is a strong open-source alternative at lower cost ($6/user/month for the Teams plan). It's somewhat less polished than 1Password but has excellent security and is transparent about its implementation.
Microsoft Authenticator and built-in browser password managers are free but lack the team management and sharing features that make a dedicated password manager valuable for businesses. They're fine for personal use; less suitable for business credential management.
Whatever you choose, the most important step is adoption. A password manager that sits unused doesn't help. Rollout should include a brief training session, enforcement of password manager use for new credentials, and a plan for gradually migrating existing credentials into the vault.
Getting started
The fastest path to impact: choose a password manager, set it up for your IT admin or owner first, then roll it out to all employees in one session. Have employees install the browser extension and mobile app, create their account, and save the credentials for their three most-used business applications during the session.
Mandate MFA for the password manager account itself — the vault is protected by the master password, but MFA adds a critical layer of protection against credential stuffing or a compromised master password.
From there, progressively migrate shared credentials into shared vaults, and establish a policy that all new business credentials go through the password manager. Within 30 days, most businesses have moved the bulk of their credential management into a structured, auditable system.
