The blueprint for strong passwords that stand up to attacks

Your password is the front door to every account. This guide gathers current best practices to design, memorise and maintain secure combinations with help from our generator and strength checker.

1. Start with length and diversity

Longer passwords slow down brute-force attacks dramatically. Aim for at least 14 characters mixing upper and lowercase letters, numbers and special symbols. Skip predictable strings such as “1234” or “password!”, and avoid obvious substitutions like “P@ssw0rd”. The more unexpected the structure, the harder it becomes to crack.

If memorising complex strings is challenging, use passphrases: compose a sentence with unrelated words and sprinkle punctuation or digits in uncommon spots. Example: “fog-Granite!24-galaxy” is easy to remember yet resilient against automated guessing.

2. Create unique passwords for every service

Reusing credentials amplifies the impact of a breach. Once an attacker gets in, they will try the same combination elsewhere. Craft a distinctive pattern per account and rely on a password manager to store everything safely. Mnemonics help, but a vault secured with strong encryption is the best long-term ally.

3. Add extra layers with multi-factor authentication

Enable MFA wherever possible. A second factor —time-based codes, hardware keys, biometrics— blocks intruders even if they obtain your password. Store recovery codes in your manager and review access logs to spot suspicious sign-ins quickly.

4. Measure strength and monitor breaches

Before adopting a new password, run it through our password strength checker. It highlights repeated characters, predictable sequences and other weak spots. Afterwards, enable breach monitoring inside your vault or use services like Have I Been Pwned to catch exposed credentials early.

5. Keep your vault healthy

A modern password manager encrypts every entry, alerts you about weak or reused passwords and streamlines updates across devices. Protect it with a long master passphrase, enable its own MFA and keep the application patched to close known vulnerabilities.

Quick checklist before you log out

  • Minimum length: 14 characters with a mix of character types.
  • No password reuse: each account has a unique combination.
  • Password manager protected with multi-factor authentication.
  • Frequent checks with the strength checker and breach alerts.
  • Immediate updates when a service reports a security incident.

Strong passwords are the foundation of digital resilience. Combine solid habits, reliable tools and continuous monitoring to keep attackers at bay and protect your identity across every device.
