Most people use passwords every day, so it’s easy to forget that they can cause an extraordinary amount of damage if not managed properly. Most teams know they should use strong passwords, avoid reuse, enable two-factor authentication (2FA), and store credentials securely. But password-related breaches happen every day, not only in large enterprises but also in small teams managing a growing mix of SaaS tools, shared accounts, and fast-moving workflows.

The problem isn’t a lack of awareness. Many companies know about cybersecurity risks but believe they aren’t valuable targets for phishing attacks or ransomware, especially SMBs. Hence, they don’t look for solutions until it’s too late.

The gap between knowing the rules and having the right systems of password security in place to follow them is another common issue. When teams are expected to remember too much, move too quickly, and work across too many tools without secure ways to create, store, share, and review credentials, bad habits proliferate.

This is why breaches still happen. This article explains why passwords remain a common entry point for data breaches, which risks affect small teams most often, which tools and practices help reduce them, and where passkeys and biometric authentication fit into a stronger password security strategy.

Why are passwords still a leading cause of data breaches?

Compromised passwords are one of the easiest ways for attackers to gain access to accounts because they guard so many network entry points. In many modern organizations, employees log in to dozens of systems across email, storage, collaboration, finance, HR, development, and client-facing tools, all of them being a potential entry point for breaches.

Weak credentials create a wide attack surface, and the more passwords that team members have to manually manage, the more likely they are to use simple and weak passwords, reuse or store password insecurely, or fall for phishing scams.

There’s data that proves this: Proton’s 2026 SMB cybersecurity report found that nearly one in four SMBs experienced a cyberattack in the previous 12 months, despite many already investing in tools, policies, and training. In addition, Proton’s Data Breach Observatory shows that passwords are exposed in nearly half of reported data breaches, underscoring the scale of credential-related risk.

How one password becomes a broader security risk

Passwords are still an enormous vulnerability because they can be compromised in multiple ways. A password can be easily guessed using a dictionary attack if it is weak. Reused passwords can compromise multiple accounts across different services. Passwords are also easily exposed if stored in insecure locations such as spreadsheets or message threads. Once an attacker has one valid credential, they often don’t need to “hack” anything; they just log in.

With so many underlying risks, a compromised password is not only an access problem: it’s a visibility issue, a response problem, and often a governance matter. Teams need to know which systems are affected, who had access, whether 2FA was enabled, whether the credential was shared, and whether any secrets/credentials need to be rotated or reviewed.

Modern guidance reflects that reality. The 2025 NIST password guidelines explicitly note that passwords alone are not phishing-resistant, even though they are still widely used. The document also recommends stronger controls around password length, blocklists, and secure handling, rather than relying on outdated complexity composition rules alone.

So when we discuss password security, it’s not merely a hygiene issue: it’s one of the most common ways everyday work leads to a real breach.

What common risks do small teams face with passwords?

Usually, small teams experience difficulty with password security because they need to move fast with limited time, scarce IT resources, and a growing set of tools that do not naturally create secure habits.

Password reuse

One of the biggest security threats to organizations is password reuse. A team member might use the same or similar password across multiple work accounts simply because it feels memorable and manageable. But if one of those credentials is exposed in a third-party breach, attackers can try it elsewhere. It’s incredibly easy for one leaked password to turn into multiple compromised systems.

Insecure credential storage

Another common issue is insecure credential storage. Even teams that are more conscious about security can fall back on familiar habits: passwords saved in browsers, copied into notes, kept in spreadsheets, or dropped into message threads, all increasing the risk of unauthorized access.

Over time, poor credential storage leads to a loss of control and poor access management throughout an organization. When credentials are stored in scattered places, offboarding becomes inconsistent, audits get harder, and incident response slows down because nobody knows exactly where credentials live.

Lack of visibility

Without clear visibility into credential management, many teams don’t have a clear way to answer basic questions like:

  • Who still has access to this account?
  • Has this password been reused anywhere else?
  • Was 2FA enabled?
  • Has this credential appeared in a breach?
  • How quickly can we identify and change it if something goes wrong?

Without these answers, password security can only be reactive. Teams only discover weaknesses after a phishing incident, a suspicious login, or even a breach.

Phishing

Strong awareness helps, but phishing remains one of the most common attack vectors. Passwords can still be entered into malicious sites, especially when attackers use convincing login pages or urgency-driven tactics. This is why passwords alone are not enough. Additional security layers like 2FA, passkeys, and secure credential workflows are essential.

Gaps in password and access policies 

Many small teams rely on informal practices rather than defined policies. People may know they should use strong passwords, but there are often no clear requirements for password length, reuse, rotation, or how credentials should be stored, shared, monitored, and revoked.

Without a defined  password policy, credential management becomes inconsistent. Over time, this leads to gaps in security, especially as teams grow and workflows become more complex.

Poor tooling and controls

Finally, controls around credential management and security are often inconsistent or nonexistent. As a result:

  • 2FA is enabled in some systems but missing in others.
  • Passwords are handled in an ad-hoc way instead of using approved business tools.
  • Lack of centralized monitoring for weak, reused, or compromised credentials

The result is an ineffective security approach that appears reassuring on the surface but leaves common real-world threats unaddressed. Password security follows the same pattern: awareness exists, but the approach is ineffective.

Which tools and best practices help prevent password-related breaches?

A single control is rarely effective to protect against password-related breaches. Risk is  reduced by combining practical measures that prevent weak habits and make secure practices easier to adopt.

Strong, unique passwords

Weak passwords are rarely chosen because people think they are ideal. They are used because they are easy to remember and quick to type in across multiple systems. 

Using long, random, and unique passwords for every account helps reduce the risk and impact of password-related breaches.

Free tools like password generators and password strength testers can help to create strong passwords and identify weak credentials. However, strength alone is not enough if passwords are reused across services.

Two-factor authentication (2FA)

2FA remains one of the most effective ways to prevent account compromise from stolen passwords, especially in phishing and credential stuffing scenarios, because it adds a second layer of protection in case a password is leaked, guessed, or reused.

The best password security programs enforce 2FA where possible, especially for email, admin accounts, finance tools, identity systems, and remote access.

Password manager

A business password manager like Proton Pass for Business addresses the core causes of password-related breaches: the need for people to create, remember, and manually type passwords across too many systems.

Instead of relying on memory, teams can generate strong, unique passwords for every account, store them in encrypted vaults, and autofill them when needed, removing much of the reason to create weak passwords or reuse credentials.

A business password manager also provides greater access control, an operational need for businesses. Teams will always need secure password sharing; the difference is whether that happens within governed, secure workflows or through chat, email, spreadsheets, and copied plain text. When access is managed through a secure system, it can be granted and revoked more reliably.

Strong and enforceable password policies

Teams need clear, documented standards that are consistently applied and enforced, including:

  • Minimum password length
  • Unique passwords for every account, with no reuse across systems
  • Approved storage methods
  • Secure sharing rules
  • Event-based reset policies
  • Clear MFA requirements

A strong password policy backed by efficient and user-friendly tools helps turn password security from a personal preference into an organizational standard everyone can adhere to with ease. With a password manager, these policies can be enforced in practice and applied consistently across teams.

Monitoring for compromised passwords

Following best credential security practices is only the starting point. Teams also need the ability to know if credentials have been exposed in a breach, or when weak and reused passwords are creating preventable risk across the organization.

Monitoring provides early visibility. Instead of reacting only after suspicious activity or account compromise happens, teams can quickly identify vulnerable credentials and rotate them before attackers have a chance to gain unauthorized access.

Access control and review

Secure access is not only about how strong credentials are. It also depends on who can access, which accounts are shared, whether access remains appropriate, and whether former employees or contractors retain credentials they no longer need.

That is why effective access control improves security in two ways: by strengthening credentials, and by establishing clear processes for how access is granted, reviewed, and revoked over time.

Ongoing security awareness and training 

Employees must understand how to identify phishing attempts, why password reuse creates risk, where credentials can and cannot be stored, what tools are approved to use, and how to report suspected activity quickly.

The key is to treat training and awareness as part of normal operations, not as a checkbox exercise. Password security is stronger when secure habits are built into everyday workflows and reinforced consistently over time.

Passkeys and biometric authentication

Alternative methods such as passkeys and biometric authentication are becoming increasingly important as part of a modern authentication strategy.

  • Passkeys rely on device-bound authentication rather than shared secrets, addressing key weaknesses of passwords, such as phishing and reuse risks.
  • Biometric authentication can also improve usability, especially on devices, but is typically used locally to unlock an authentication secret or device rather than being transmitted as the primary secret itself. That makes them useful, but not a direct replacement for all password and access management needs. NIST’s guidance makes this distinction as well when discussing activation secrets and authenticators.

For most teams today, the question is not whether to use passwords, passkeys, or biometrics. In practice, a layered approach is the answer: 2FA should be used when possible, passkeys should be adopted where supported, and secure password management remains critical, as passwords are still widely used across many systems and are unlikely to disappear anytime soon.

How does effective password management improve security and compliance?

Password security is typically framed in terms of breach prevention, but that is only part of the picture. Effective password management also strengthens governance, improves audit readiness, and makes day-to-day operations more efficient by ensuring access can be reviewed, updated, and revoked as needed.

Stronger day-to-day security

Security benefits are immediate. Unique passwords limit lateral movement from reuse, encrypted vaults prevent accidental exposure, and easy, secure sharing eliminates the need to send secrets through unsafe channels. Monitoring helps identify exposed credentials early, while MFA makes it less likely that a stolen password leads to account takeover.

Better operational control

Effective credential management provides greater control across onboarding, offboarding, role changes, contractor access, and incident response. When teams know where credentials are stored, who can access them, and how to quickly rotate them, they can respond faster and more precisely when something goes wrong.

Improved support for compliance

Most frameworks and customer security reviews go beyond asking whether a company uses strong passwords. They require evidence that:

  • Credentials are managed securely
  • Access is consistently reviewed
  • Sharing is secure and controlled
  • Access can be revoked
  • Risky behaviors can be addressed

A business password manager helps establish the repeatable controls that auditors and customers require, strengthening organizational compliance.

How does Proton Pass for Business help reduce password-related breach risk?

Password-related breaches usually happen when teams need to manage too many credentials without a secure, centralized system. This leads to the same familiar issues: password reuse, insecure storage, informal sharing, limited traceability, and inconsistent access control.

Proton Pass for Business reduces this risk by giving teams a secure way to create, store, and manage credentials. Instead of relying on browsers, spreadsheets, notes, or chat threads, teams can generate strong, unique passwords, store them in encrypted vaults, and share access using secure and controllable workflows.

Stronger passwords, used consistently

One of the most immediate benefits is reducing password reuse. When unique credentials are easy to generate and retrieve, teams are much less likely to fall back on repeated or slightly modified passwords across accounts.

Better visibility and control over access

Proton Pass for Business centralizes credentials in a managed environment, making access easier to review and control. Teams gain visibility into who has access, which credentials are shared, and what needs to be updated or revoked after a role change or suspected compromise.

Safer sharing for collaborative teams

Small teams often need to hand over access quickly, especially across operations, vendors, and shared tools. However, when this sharing occurs through insecure channels, risk arises. With secure and controlled sharing workflows, businesses can reduce that exposure while making access changes easier to manage and control.

Stronger support for policy enforcement

A password policy is much easier to implement when tools enforce the behavior they require. Proton Pass for Business helps teams put rules around password strength, sharing, 2FA adoption, and credential review into practice, rather than relying on memory or informal habits.

This is one of the benefits of a business password manager. It can’t eliminate all authentication risks, but it directly addresses many of the causes that lead to  password-related breaches.
