Password and Multi-Factor Authentication Best Practices for Small Businesses

Passwords are still one of the most common weak points in a small business. Multi-Factor Authentication (MFA) adds a second layer of protection when a password is guessed, reused, or stolen.

Why this matters

Small teams often share passwords through text messages, spreadsheets, sticky notes, or old documents. That makes it difficult to know who has access and impossible to safely remove access later.

Use this resource when

  • Employees share logins or passwords.
  • Passwords are stored in spreadsheets or messages.
  • Multi-Factor Authentication (MFA) is optional or inconsistent.
  • You need a basic password policy that people can follow.

What to review

  • Which systems use shared passwords.
  • Which accounts have Multi-Factor Authentication (MFA) enabled.
  • Where passwords are currently stored.
  • Who has access to shared vaults or administrative accounts.
  • How passwords are removed when an employee leaves.
Step by step

Practical checklist

  1. List the systems your team logs into each week.
  2. Identify shared passwords and replace them with named accounts where possible.
  3. Choose a password manager for business use.
  4. Create shared vaults based on roles instead of giving everyone everything.
  5. Enable Multi-Factor Authentication (MFA) for email, finance, cloud storage, and administrator accounts.
  6. Document the process for adding and removing password access.
Avoid these issues

Common mistakes

  • Using one shared login for the whole team.
  • Letting browsers save business passwords on shared devices.
  • Sending passwords through email or text messages.
  • Using Multi-Factor Authentication (MFA) only for administrators.
  • Forgetting to remove password vault access during offboarding.
