How to Create a Strong Password

Weak and reused passwords remain the leading cause of data breaches. According to recent research, 81% of hacking-related breaches involve weak, reused, or stolen credentials — and analysis of 19 billion leaked passwords found that only 6% were unique. Here is how to create passwords that actually protect your accounts.

What Makes a Password Strong in 2026?

Password cracking technology has advanced significantly in recent years. What was considered a strong password five years ago may now be crackable in minutes. Current best practices call for passwords that meet these criteria:

Length Is More Important Than Complexity

Security experts and NIST (the National Institute of Standards and Technology) now emphasize length over complexity. A longer password is exponentially harder to crack than a shorter one with special characters. Aim for:

• Minimum 16 characters for important accounts
• 20+ characters for your most critical accounts (email, banking, password manager)
• Research shows that 88% of passwords used in successful attacks were 12 characters or fewer

Use Passphrases

A passphrase is a sequence of random words that is both long and easy to remember. For example:

• Good: "correct horse battery staple" (four random words)
• Better: "purple telescope wanders beneath frozen lakes" (six random words)
• Best: A random passphrase generated by your password manager

The key is randomness. Do not use quotes, song lyrics, book titles, or other phrases that could be guessed or found in a dictionary attack database.

Make Every Password Unique

This is non-negotiable. Every account must have its own unique password. When attackers breach one service and obtain your credentials, they immediately try those same credentials on hundreds of other popular sites in what is known as a credential stuffing attack. With an estimated 193 billion credential stuffing attempts happening annually, reusing passwords is one of the biggest security mistakes you can make.

Why You Need a Password Manager

If every password must be unique, long, and random, it becomes impossible to remember them all — and that is exactly why password managers exist. A password manager generates, stores, and auto-fills strong passwords for all your accounts. You only need to remember one master password.

Recommended Password Managers

• 1Password: Excellent user experience, strong security, and good family plan options. Works across all major platforms and browsers.
• Bitwarden: Open-source and offers a generous free tier. A great choice for privacy-conscious users who want to verify the code themselves.
• Dashlane: Includes built-in VPN and dark web monitoring features alongside core password management.
• Apple Passwords: Built into iOS, macOS, and now Windows via iCloud. Convenient if you are already in the Apple ecosystem.

Passkeys: The Future of Authentication

Passkeys are a modern alternative to passwords that use cryptographic key pairs instead of text-based credentials. They are phishing-resistant by design — there is no password to steal, guess, or reuse.

Here is how passkeys work:

• When you create a passkey for a site, your device generates a unique cryptographic key pair
• The private key stays on your device (or in your password manager), while the public key goes to the website
• To sign in, you authenticate locally using biometrics (fingerprint or face) or your device PIN
• The website never sees your private key, so there is nothing for attackers to steal in a breach

Major services including Google, Apple, Microsoft, Amazon, and many others now support passkeys. Whenever a service offers passkey support, it is worth enabling it as your primary login method.

How to Check If Your Passwords Are Compromised

Even if you follow best practices today, your older passwords may already be in breach databases. Here is how to check:

Have I Been Pwned

Visit haveibeenpwned.com to check if your email address has appeared in known data breaches. The site also offers a Pwned Passwords tool at haveibeenpwned.com/Passwords that lets you check if a specific password has been seen in any breach — it uses a privacy-preserving technique called k-anonymity, so your full password is never transmitted to their servers.

Built-In Password Auditing

Most password managers include a security audit feature that flags weak, reused, or compromised passwords across all your stored credentials. Use this regularly:

• 1Password: Watchtower feature
• Bitwarden: Vault Health Reports
• Google Chrome: Password Checkup in settings
• Apple: Security Recommendations in Passwords settings

Enable Two-Factor Authentication Everywhere

Even a strong password can be compromised. Two-factor authentication (2FA) adds a second layer of defense. Prioritize these methods in order of security:

1. Hardware security keys (YubiKey, Google Titan) — the most secure option
2. Authenticator apps (Google Authenticator, Authy, Microsoft Authenticator) — strong and widely supported
3. SMS codes — better than nothing, but vulnerable to SIM-swapping attacks

Protecting Your Broader Digital Footprint

Strong passwords protect your accounts, but your personal information may still be exposed through data brokers and people-search sites. PrivacyOn complements your password security by monitoring over 100 data brokers for your personal data, scanning the dark web for leaked credentials, and automatically removing your information when it is found. With family plans covering up to 5 people and 24/7 monitoring starting at just $8.33 per month, PrivacyOn provides a comprehensive layer of privacy protection alongside your strong password practices.
