Why do you need a password policy?
Stolen, weak, or reused passwords can give hackers the keys to your entire business. A single security breach costs well over $1 million, on average.
A strong password policy reduces the risk of data breaches, closes gaps caused by human error, simplifies compliance audits, and sets clear expectations for your team. It turns password security from a guessing game into a consistent, enforceable standard.
What is a password policy?
A password policy greatly reduces the risk of data breaches by setting a consistent security baseline for everyone, ensuring every team member follows the same strong practices.
A strong policy provides clear and unambiguous rules for:
Password creation
A good password policy sets concrete requirements for minimum length and explicitly bans the use of common or previously compromised passwords.
Password management and storage
It dictates how passwords must be stored. This includes banning risky methods like spreadsheets or sticky notes and mandating the use of a secure, encrypted password manager.
Access control and sharing rules
Access rules govern who can access what and how they prove their identity. It forbids credential sharing via email or chat and defines the proper procedure for granting access using role-based controls. It also makes multi-factor authentication (MFA, sometimes referred to as 2FA) a mandatory layer of security.
Employee management
A password policy accounts for changes in your team. It defines clear procedures for providing credentials during employee onboarding and immediately revoking access when an employee departs. This prevents orphaned accounts and ensures former employees cannot access company data.
Key password security standards and what they mean for you
You don’t need to reinvent the wheel. Leading global security and government organizations have already researched and documented what works. Here’s what they recommend:
NIST SP 800-63B: Published by the US National Institute of Standards and Technology, this is the gold standard for modern authentication. It champions long passphrases, the use of deny lists to block bad passwords, and advises against outdated rules such as mandatory resets. See the 2025 NIST password guidelines
CIS control: The Center for Internet Security provides a prioritized set of best practices that recommends a 14-character minimum for password-only accounts and strongly encourages the use of password managers.
ISO/IEC 27002: This global standard from the International Organization for Standardization (ISO) focuses on information security management. For passwords, it emphasizes secure storage in vaults and changing credentials only when a compromise is suspected.
PCI DSS: The Payment Card Industry Data Security Standard is a stringent, mandatory standard established by major credit card companies for any business that processes card data. It requires more stringent controls, such as periodic password rotation, for in-scope systems.
Nearly 50% of all breaches involve stolen credentials
According to the latest industry reports, stolen credentials remain the number one entry point for attackers. This highlights a critical truth: A password policy is only as strong as its enforcement.
With Proton Pass for Business, you can turn your policy into an active defense:
Automatically block weak and reused passwords at creation.
Enforce two-factor authentication (2FA) across your organization.
Share credentials securely with teams without ever exposing them.
Password policy best practices to protect your business
Password standards have come a long way in the last three decades. Modern password policies are simpler and more effective than ever. Based on the latest guidance from cybersecurity authorities, the focus has shifted away from complex rules that frustrate users.
1. Mandate a longer minimum length
Length is the most important factor in password strength. A short, complex password like L817!a2 can be cracked in minutes, while a long passphrase like fridge telescope jigsaw quarry could take centuries.
- Enforce a minimum of 12 characters.
- For admins and privileged accounts, make it 16 characters.
2. Ban bad passwords with a deny-list
Don’t let people choose simple passwords like Password123! or Spring2025. Your policy should forbid:
- Commonly used passwords (from public breach lists)
- Dictionary words
- Repetitive or sequential characters (111111, abcdefg)
- Company-specific terms (product names, office locations)
3. Eliminate mandatory password expiration
Forcing your team to change their password every 90 days is an outdated practice that experts now advise against. It encourages people to create weak, predictable patterns they can remember (e.g., Password2025!, Password2026!).
- Only force a password reset upon evidence or suspicion of compromise.
4. Require multi-factor authentication (MFA) everywhere
A password should only be the first factor. MFA is your single best defense against account takeovers from stolen credentials.
Enforce MFA on all critical systems using an authenticator app, push notification, or a hardware security key.
5. Deploy a password manager for your business
You can't expect employees to create and remember unique 16-character passphrases for dozens of accounts. A password manager makes perfect security hygiene easy.
- It generates, stores, and autofills strong credentials.
- It enables secure sharing for teams without sending passwords over text message or email.
- It can enforce team-wide password policies and security standards.
- It alerts you if your team’s credentials are exposed on the dark web or if passwords are weak.
With Proton Pass for Business, you can set policy requirements (like minimum length) and provide the tool your team needs to meet them effortlessly.
Common mistakes in corporate password policies
Many well-intentioned policies can make security worse. Avoid these common pitfalls:
Forcing complex composition rules
(for example, passwords must include an uppercase, a number, and a symbol)
Best practice: Prioritize long passwords over complexity. Each character added to a password increases its strength exponentially; focusing on length provides far more security than forcing character types.
Blocking the ability to paste passwords
Best practice: Allow password pasting so employees can use a password manager. Blocking pasting forces people to create shorter, memorable (and weaker) passwords they can type manually.
Sharing accounts among multiple employees
Best practice: Use individual accounts with role-based access. Shared logins eliminate accountability and force password changes whenever someone leaves, creating unnecessary risk and downtime.
Forgetting to secure software and API credentials
Best practice: Store software and API secrets in a dedicated vault. Hardcoded credentials in scripts or config files create hidden, high-impact security risks that attackers can easily exploit.
Password policy template
Use this template as a starting point. Adapt it to your organization’s needs and include it in your employee handbook and onboarding materials.
Business password policy
- Purpose: To establish rules for creating, using, and managing passwords to protect company data and systems.
- Scope: This policy applies to all employees, contractors, and vendors accessing company resources.
- Requirements:
- Length: Minimum of 16 characters. Passphrases are encouraged.
- Uniqueness: Every password must be unique. Reusing passwords across different work systems or between personal and work accounts is forbidden.
- Deny-List: Passwords must not be on a list of known compromised passwords or contain company-specific terms.
- Rotation: Passwords must be changed immediately if a compromise is suspected. There is no mandatory periodic expiration.
- MFA: Multi-factor authentication must be enabled on all services that support it.
- Storage: All passwords must be stored in the company-provided password manager (Proton Pass). Passwords must never be written down or stored in insecure files (like spreadsheets and text documents). Employees should memorize a unique four-word master passphrase to access their password manager.
- Sharing: Credentials must never be shared outside of the password manager. Use the secure sharing feature within the password manager for role-based access.
4. User responsibilities:
- Protect your credentials at all times.
- Report any suspected account compromise to the IT department immediately.
- Complete the annual security awareness training.
How to implement your password policy (step-by-step)
Rolling out a new password policy requires a thoughtful, multi-step approach that combines clear documentation, the right technology, and effective communication.
1. Define and document your policy
The first step is to formalize your rules in an official password policy document. Be sure to clearly define the minimum password length, MFA requirements, and rules for storing and sharing credentials.
Most importantly, note any exceptions (for example, added rules for credit card data) and limit these stricter requirements to specific systems (like payments) to prevent creating unnecessary friction elsewhere.
2. Deploy a central enforcement tool
A password policy that relies on manual human enforcement will fail. You need a tool that makes following the rules the default, automatic, and easy option.
Rolling out a password manager like Proton Pass across your organization gives you a single dashboard to enforce, monitor, and update your requirements.
3. Configure your technical controls
Once your password manager is in place, configure the technical settings across your key systems to reflect your policy. This typically involves:
- Proton Pass: Set your business-wide requirements, such as a mandatory minimum password length.
- SaaS and software (Microsoft 365, Google, Jira, Slack): Configure built-in tools to enforce MFA registration and block common or breached passwords using deny-lists.
Across all critical systems: Enable account lockout and session timeout rules to protect against brute-force attacks.
4. Train your team and communicate clearly
For a policy to be effective, your team must understand why it exists and how it benefits them.
A short training session that demonstrates how the password manager eliminates the need to remember complex passwords will get much more buy-in than a simple policy memo. Focus on the benefits: No more forgotten passwords, simpler logins, and secure sharing.
5. Monitor, adapt, and improve
Regularly use your password manager’s admin dashboard to get insights into your organization’s security posture.
Look for weak or reused passwords and identify areas where more training may be needed. Plan to formally review the entire password policy document regularly to ensure it keeps pace with emerging threats and new technologies like passkeys.
