Password security advice has evolved significantly over the years, but outdated recommendations and misconceptions continue to circulate widely. These persistent myths not only create confusion but can actually lead to less secure practices. In this article, we'll examine the most common password security myths, explain why they're incorrect, and provide updated guidance based on current security research and best practices.
Myth #1: Complex Passwords with Special Characters Are Always More Secure
For decades, the standard password advice was to create complex passwords with a mix of uppercase letters, lowercase letters, numbers, and special characters. This led to passwords like "P@ssw0rd!" that are difficult for humans to remember but surprisingly easy for computers to crack.
The Reality
Modern password-cracking techniques are sophisticated enough to account for common character substitutions (like 'a' to '@' or 'o' to '0'). These predictable patterns actually make passwords less secure than their length would suggest.
Current research from organizations like NIST (National Institute of Standards and Technology) emphasizes that password length is a more important factor than complexity. A longer password or passphrase, even if it uses only lowercase letters, can be more secure than a shorter complex one.
Updated Guidance
- Focus on length over complexity—aim for at least 16 characters when possible
- Consider using passphrases (multiple words together) for better memorability and security
- If you do use special characters, integrate them naturally rather than as simple substitutions
- Use our password generator to create strong passwords that balance length and complexity
Myth #2: Changing Passwords Frequently Improves Security
Many organizations still require users to change their passwords every 30, 60, or 90 days, based on the belief that this practice limits the damage from undetected password breaches.
The Reality
Research has consistently shown that mandatory password changes often reduce security rather than enhance it. When forced to change passwords frequently, users typically:
- Make minimal changes to existing passwords (e.g., changing "Password1" to "Password2")
- Create simpler passwords that are easier to modify
- Develop predictable patterns that attackers can anticipate
- Write down passwords more frequently due to difficulty remembering them
NIST and other security organizations now recommend against arbitrary password expiration policies, as they provide minimal security benefits while imposing significant usability costs.
Updated Guidance
- Change passwords only when there's evidence of compromise
- Focus on detecting breaches through monitoring services rather than preemptive changes
- Use unique passwords for each service so that a breach of one doesn't affect others
- Implement multi-factor authentication for additional protection
Myth #3: Password Hints and Security Questions Enhance Account Security
Many services still offer password hints or security questions as account recovery options, presenting them as security features.
The Reality
Password hints and traditional security questions often create security vulnerabilities rather than enhancing protection. These mechanisms are problematic because:
- Hints frequently reveal too much information about the password
- Common security questions (mother's maiden name, first pet, etc.) are often easily researched through social media or public records
- Answers to security questions are typically much less complex than passwords themselves
- Many people provide consistent answers across different services, creating a single point of failure
High-profile account compromises have frequently involved security questions rather than password breaches.
Updated Guidance
- Avoid using password hints entirely
- If you must use security questions, provide random, password-like answers (and store them in your password manager)
- Prefer services that use more secure account recovery methods like email verification or multi-factor authentication
- Never provide truthful answers to security questions that could be discovered through public information
Myth #4: Hiding Written Passwords Is Secure Enough
Many people believe that writing down passwords is acceptable as long as the written record is kept in a physically secure location, like a locked drawer.
The Reality
While digital threats are more common, physical security shouldn't be overlooked. Written passwords are vulnerable to:
- Casual snooping by visitors, family members, or coworkers
- Theft during break-ins
- Being photographed or observed during use
- Loss or accidental disposal
Additionally, written password lists are difficult to keep updated and often don't include important context like the associated username or service.
Updated Guidance
- Use a reputable password manager instead of written records
- If you must write down passwords, consider recording only partial information or hints that are meaningful only to you
- Never keep written passwords near your computer or in obvious locations like desk drawers
- Consider more secure physical storage options like a safe for critical credentials
Myth #5: Password Managers Are Too Risky Because They Create a Single Point of Failure
Many people avoid password managers due to concerns that if the master password is compromised, all their accounts would be at risk.
The Reality
While password managers do create a single master password to protect all others, this concern must be weighed against the significant security benefits they provide:
- They enable the use of unique, complex passwords for every service
- They eliminate password reuse, which is one of the most significant security risks
- Modern password managers use strong encryption and zero-knowledge architectures
- Most support multi-factor authentication for additional protection
The security risk of using a password manager is far lower than the risk of password reuse or using simple, memorable passwords across multiple services.
Updated Guidance
- Use a reputable password manager with strong security practices
- Create a strong master password using techniques from our memorable passwords guide
- Enable multi-factor authentication on your password manager account
- Keep your password manager software updated
- Consider a hybrid approach where critical passwords (like banking) are memorized while others are stored in the manager
Myth #6: HTTP Basic Authentication (Browser Pop-up) Is Secure
Some users believe that the browser's built-in authentication pop-up (HTTP Basic Authentication) provides adequate security for websites.
The Reality
HTTP Basic Authentication has significant security limitations:
- Credentials are transmitted with every request, increasing exposure
- Without HTTPS, credentials are sent in an easily decoded format
- It typically doesn't support multi-factor authentication
- It offers limited protection against brute force attacks
- Users can't log out without closing the browser
Modern web applications use more secure authentication mechanisms with session management, encryption, and additional security features.
Updated Guidance
- Be cautious of sites that rely solely on HTTP Basic Authentication
- Ensure any site using this method is accessed via HTTPS
- Use a unique, strong password for these sites
- Close your browser completely to terminate the authentication session
- Prefer services with modern authentication systems when possible
Myth #7: Passwords Stored in Browsers Are Secure
Many users rely on their browsers to store and auto-fill passwords, assuming this built-in functionality is secure.
The Reality
Browser password managers have improved but still have security limitations:
- Protection varies significantly between browsers
- Some browsers store passwords in a way that can be easily extracted if someone has access to your device
- Browser sync features may transmit passwords with varying levels of security
- They typically lack advanced features like breach monitoring or secure sharing
While browser password storage is better than reusing simple passwords, dedicated password managers offer stronger security features.
Updated Guidance
- Consider a dedicated password manager instead of browser storage
- If using browser password storage, ensure your device is secured with a strong password or biometrics
- Enable the browser's master password feature if available
- Keep your browser updated to benefit from security improvements
- Be cautious about which passwords you allow the browser to save
Myth #8: If a Website Limits Password Length, It Must Be for Security Reasons
Some users assume that websites limiting password length (e.g., to 8-12 characters) do so for security reasons.
The Reality
Password length restrictions are almost always a sign of outdated security practices, not enhanced security. These limitations typically indicate:
- The service may be storing passwords in plaintext or using weak encryption
- The system is likely using outdated database or authentication systems
- Security may not be a priority for the organization
Properly designed authentication systems can handle passwords of virtually any length, as they store only fixed-length cryptographic hashes of passwords, not the passwords themselves.
Updated Guidance
- Be cautious about services with strict password length limitations
- Use unique passwords for these services to limit damage if they're compromised
- Consider whether the service contains sensitive information that warrants additional security measures
- When possible, choose services that allow longer passwords and implement modern security practices
Myth #9: Using a VPN Makes Your Passwords Secure on Public Wi-Fi
Many users believe that using a VPN on public Wi-Fi completely protects their passwords and account security.
The Reality
While VPNs provide valuable protection by encrypting your internet traffic, they don't address all password security risks:
- VPNs don't protect against phishing websites designed to steal credentials
- They don't prevent malware on your device from capturing passwords
- They don't protect against password reuse if one service is breached
- The quality and trustworthiness of VPN providers vary significantly
VPNs are an important security tool, but they're just one component of a comprehensive security approach.
Updated Guidance
- Use a reputable VPN on public Wi-Fi, but don't rely on it as your only security measure
- Ensure websites use HTTPS (look for the padlock icon) before entering passwords
- Be vigilant about phishing attempts even when using a VPN
- Use multi-factor authentication when available
- Consider using a dedicated device for sensitive transactions
Myth #10: If You're Not a High-Value Target, Password Security Doesn't Matter Much
Some users believe that sophisticated hackers only target high-profile individuals or organizations, so average users don't need to worry much about password security.
The Reality
Modern cyberattacks are largely automated and opportunistic, targeting vulnerabilities rather than specific individuals:
- Credential stuffing attacks automatically try breached passwords across thousands of websites
- Phishing campaigns target millions of users indiscriminately
- Compromised accounts can be valuable for spam, fraud, or as stepping stones to other targets
- Personal information and access have monetary value on dark web marketplaces
Everyone with an online presence is a potential target, regardless of their perceived value or profile.
Updated Guidance
- Apply strong security practices to all your accounts, not just those you consider high-value
- Recognize that email and social media accounts are particularly valuable targets
- Be aware that compromised accounts can affect your reputation and relationships
- Consider the interconnected nature of your digital life—one compromised account often leads to others
