Password Security Best Practices: What You Need to Know

Written by Mitnick Security | Feb 21, 2025 7:30:00 PM

Too many accounts, too many passwords. No wonder people use “password123” or repeat the same one everywhere, skipping multi-factor authentication and password managers because security feels like extra work. 

The problem is that most people assume they won't be targeted, not realizing that hackers can crack an 8-character password in seconds. Even just one weak password can cost you stolen accounts, drained bank accounts, and identity theft. 

Ignoring password security can quickly turn into an expensive nightmare and weak passwords make you an easy target. 

Following, we’ll share password security best practices and strong password examples that will instantly improve your password strength and give you peace of mind.

 

The Threat of Password Cracking

In 2024, a Forbes report revealed that smart-guessing technology had collectively cracked 87 million passwords in less than 60 seconds.

This means your password might not be as secure as you think, and that's because bad actors are no longer just guessing; they're using advanced password-cracking algorithms.

 

How Hackers Crack Passwords So Fast

Threat actors use multiple techniques to expose passwords, including:

  • Brute force attacks: Rapidly trying every possible combination.
  • Dictionary attacks: Running through lists of commonly used passwords.
  • Credential stuffing: Testing stolen passwords from past breaches.
  • AI-driven password guessing: Using machine learning to predict weak passwords.

 

With these tools, short and simple passwords like password123 orqwerty are broken almost instantly. Even passwords that seem strong can be cracked if they follow predictable patterns.

What This Means for You

If your password isn't long, unique, and random, it's vulnerable. Using strong password security best practices is critical to protecting your sensitive data.

 

Best Practices for Password Security

The right security habits often serve as your first line of defense against threat actors. Here are the most common methods they use and how you can stay one step ahead.

1. Implement Multi-Factor Authentication (MFA)

A password alone isn’t enough anymore. Multi-factor authentication (MFA) adds an extra layer of security by requiring two or more verification steps before granting access to your account.

Even if hackers steal your password, they still can’t log in without the second factor.

Standard MFA methods include:

  • One-time codes sent via text or email
  • Authenticator apps like Google Authenticator or Authy
  • Biometric verification (fingerprint or facial recognition)

 

Enabling MFA greatly reduces the risk of unauthorized access, making it much harder for data thieves to break into your accounts. Whenever possible, choose app-based authentication or biometrics over SMS codes, as SIM-swapping attacks can compromise text-based authentication.

2. Switch To Longer Passphrases

Hackers rely on weak, predictable passwords to break into accounts. If your password is short or includes obvious details, like your birthday or pet’s name, it’s an easy target. Instead, follow password security best practices by switching to a longer, more complex passphrase.

The longer your password, the harder it is to crack. Modern hackers use brute-force attacks to guess passwords in seconds, but increasing your password length exponentially improves password strength.

Aim for at least 16 characters using a mix of uppercase and lowercase letters, numbers, and symbols.

Strong Password Examples

Not sure where to start? Here are a few strong password examples:

  • G7$vTz9#QpLmX3aB (Random and secure)
  • Blue-Cloud!River#29 (Long and easy to remember)
  • T!gerRuns2@Sunset (Passphrase-based for better recall)

 

Avoid predictable substitutions like "P@ssw0rd" or "Admin123"—hackers know those tricks.

Using unique, long passwords for every account might seem overwhelming, but password managers make it easy. These tools securely store and autofill your passwords, so you don’t have to remember them all.

3. Utilize a Password Manager

Let’s face it: keeping track of multiple complex passwords is nearly impossible. Yet password security best practices recommend using unique, strong passwords for every login.

A password manager solves this problem by securely storing and auto-filling your passwords so you don’t have to remember them all. Without a password manager, you’re more likely to:

  • Reuse passwords across accounts (making it easier for hackers to breach multiple logins)
  • Use weak, easy-to-remember passwords (reducing your password strength)
  • Write down passwords or save them in unsecured places (leaving them vulnerable to theft)

 

Password managers like 1Password, LastPass, and Bitwarden generate and store long, unique passwords for every account, allowing you to improve password strength without sacrificing convenience.

Stronger Security Without the Hassle

Using a password manager means you can create strong passwords without worrying about remembering them and because each account has its own unique password, it reduces the risk of credential stuffing attacks. Plus, autofill features save time while keeping your logins secure.

4. Do Not Share Log In Information

It might seem like common sense, but one of the biggest cybersecurity risks comes from sharing your login credentials, even with people you trust.

Threat actors use social engineering tactics to deceive people into handing over their passwords. Instead of hacking into your account directly, they pose as trusted sources, like your boss, IT department, or even your bank, to convince you to share sensitive information.

Common tactics include:

  • Phishing Emails & Texts: Messages that look legitimate but trick you into revealing your login details.
  • Fake IT Support Calls: Scammers pretending to be tech support asking for your password.
  • Urgent Requests: Messages claiming your account is at risk unless you act immediately.

 

How to Protect Yourself

Never share your password; no exceptions. 

Hackers use fake urgency to trick you. If someone asks for your login, verify their identity another way. Use Multi-Factor Authentication (MFA) to keep your accounts safe, even if your password gets stolen.

Think Before You Click

If you ever receive an email, text, or phone call asking for your password, security codes, or other sensitive data, stop and verify. Legitimate organizations will never ask for your password via email or phone.
