We have all heard the advice: “Use strong passwords.” But what does that actually mean? Is it just about mixing numbers and symbols? Or is there more to creating a secure password? And can they really protect you from hackers? Let’s break down what makes a password strong and why it’s important in protecting your digital life.
Why Do We Need Strong Passwords?
Passwords are the first line of defense between your sensitive information and potential cybercriminals. When your password is weak, hackers can use techniques like brute force attacks to guess it and gain access to your accounts. In fact, a simple password made up of just eight numbers can be cracked in 37 seconds.
A company called Hive Mind released a password table which displays the time needed to hack a password using the best consumer-accessible hardware. The table is updated every year. According to that table, it would take a hacker 652 billion years to crack a 15-digit password that has only lower and uppercase letters.
The take-away? With our increasing reliance on online services—from banking to social media—strong passwords are more critical than ever.
What Exactly Makes a Password Strong?
A strong password is more than just a random string of letters and numbers. It needs to meet a few specific criteria to be truly secure:
- Length: The longer the password, the better. A strong password should ideally be at least 12–16 characters Shorter passwords can be cracked much faster, especially with today’s powerful computing tools.
- Complexity: A mix of upper and lowercase letters, numbers, and symbols makes your password harder to guess. Avoid predictable patterns like “Password123!” or substituting numbers for letters in obvious ways (e.g., “P@ssw0rd”). Instead, aim for a more randomized set of characters.
- Unpredictability: Strong passwords are random. Avoid using dictionary words, common phrases, or personal information (such as birthdays or pet names), which are easy for hackers to guess.
- Uniqueness: Reusing passwords across multiple accounts is a major risk. Even the strongest password can become weak if it’s been used on a compromised platform. Each account should have its own unique password.
Examples of Strong vs. Weak Passwords
Here are a few comparisons to illustrate what makes a password strong or weak:
- Weak Password: John1234
- Short and includes easily guessed personal information (name) combined with a simple numeric sequence.
- Strong Password: G7&lX*5bQ#12@T
- Long, complex, and difficult to predict.
- Weak Password: Summer2023!
- Although it includes a symbol and numbers, it’s based on a common word and predictable pattern (season and year). Hackers could easily guess this with a dictionary or brute force attack.
- Strong Password: 5J&l3xW!p^R9M1$
- This password is random, long, and includes a variety of letters, numbers, and symbols. There’s no clear pattern or recognizable words, making it significantly more secure.
- Weak Password: ilovepizza
- While fun and memorable, this password is short, lacks complexity, and is based on a simple phrase that could be guessed easily by an attacker.
- Strong Password: ^P3zZ@7Love!r2A
- While it still references pizza, this password is much stronger due to its length, combination of special characters, numbers, and uppercase/lowercase letters, making it far harder to crack.
Notice how the strong passwords are both long and include a mix of different types of characters. A strong password does not necessarily have to look random to you, but it should be unpredictable to anyone trying to guess it.
How to Create Strong Passwords Easily
Coming up with a strong password on your own might seem like a challenge, but it doesn’t have to be. Here are a few methods you can use to generate strong passwords:
- Passphrases: Instead of random characters, try using a long string of unrelated words. For example, a password like CoffeeTrainAppleDuckBoat! is both easy to remember and incredibly difficult to crack because of its length and randomness.
- Password Generators: Tools like password managers often include random password generators that can create secure, complex passwords for you.
The Role of Password Managers
One of the best ways to manage strong passwords is by using a password manager. These tools allow you to store all your passwords in a secure, encrypted database. This eliminates the requirement for you to memorize them all. You only need to remember one master password, which should follow the same guidelines for strength.
Why Strong Passwords Aren’t Enough
Even with a strong password, additional security measures are crucial to fully protect your accounts. Here’s why:
- Data Breaches: Even strong passwords can be compromised in a breach, so it’s important to use unique passwords for each account.
- Phishing: Hackers may trick you into revealing your password, so be careful about clicking on links or entering login information on unfamiliar sites.
- Credential Stuffing: Reusing passwords makes it easier for hackers to access multiple accounts if just one is compromised.
Additional Security Measures
- Multi-Factor Authentication (MFA): Always enable MFA wherever possible. This adds an extra layer of protection by requiring a second form of verification, like a code sent to your phone.
- Password Hygiene: Change your passwords if you believe they’ve been compromised. However, if you’re using strong, unique passwords, frequent changes aren’t as necessary as they once were.
Testing Your Password Strength
Wondering if your password is strong enough? Tools like How Secure is My Password? can help you assess the time it would take for a hacker to crack it. Remember, the stronger and longer your password, the more secure your online presence.
Final Thoughts
Using strong passwords is one of the most effective steps you can take to protect your personal and professional data from cyber threats. By focusing on length, complexity, unpredictability, and uniqueness, you can create passwords that are virtually uncrackable.
If managing your passwords feels overwhelming, consider using a password manager to handle the heavy lifting for you. And always remember: strong passwords combined with tools like two-factor authentication give you the best defense against hackers.

Top Questions about Strong Passwords
What is a strong password example?
The password “m#P52s@ap$V” is a great example of a strong password. It’s long, complex, and hard to guess. With over 10 characters, it includes a mix of uppercase and lowercase letters, numbers, and symbols, and it avoids any personal information or common words, making it much more secure.
How to pick a good password?
To pick a good password, follow these tips:
- Make it long: Aim for at least 12-16 characters. The longer the password, the harder it is to crack.
- Use a mix of characters: Include uppercase and lowercase letters, numbers, and special symbols to increase complexity.
- Avoid common words and patterns: Don’t use obvious choices like “password,” “123456,” or anything easy to guess like your name or birthdate.
- Use a passphrase: Combine unrelated words or create a memorable sentence with mixed characters, making it easier for you to remember but hard to guess.
- Don’t reuse passwords: Each account should have its own unique password to reduce the risk of multiple accounts being compromised.
- Consider a password manager: A password manager can generate and store strong, unique passwords for you, making the process easier.
These practices will help ensure your passwords are both secure and manageable.
