• Extra tips to boost your password security
• Answers to common password questions

Let‘s get started with the fundamentals of strong password creation.

What Makes a Password Strong?

When evaluating password security, there are four key elements to look for: length, complexity, unpredictability, and uniqueness. Passwords that rate highly in these areas will be exponentially harder for hackers to compromise.

Password Length

Length is one of the most important attributes of a strong password. The longer a password is, the more secure it becomes.

Why is length so crucial?

Each additional character exponentially expands the possible combinations a password could contain. An 8-character password has 208 billion potential combinations. Bumping that up to a 12-character password yields a staggering 5.7 trillion combinations!

This massive jump in complexity makes longer passwords orders of magnitude more difficult to crack. Even adding just a few extra characters takes a password from weak to strong.

How long should your passwords be?

• At minimum: 12 characters

• Better: 16 characters

• Best: 20+ characters

Of course, longer isn‘t always better if it leads to password reuse or writing down passwords. But in general, maximizing length within reason will go a long way toward keeping passwords secure.

Pro Tip: Use passphrases instead of passwords

One easy way to get length is to use multi-word passphrases rather than traditional passwords. Passphrases are simply multiple words strung together to form a password.

For example, "Red pandas are incredibly cute!" makes a great 16-character passphrase. The length alone makes it strong, and the phrase is easy to remember.

Password Complexity

Complexity refers to the types of characters used in a password. Strong passwords utilize a mix of:

• Uppercase letters
• Lowercase letters
• Numbers
• Symbols/punctuation

Adding different character types increases the variety of patterns a password could contain. This added complexity heightens the difficulty of guessing or cracking the password.

Here are some examples of weak vs. strong complexity:

• Weak: password (all lowercase letters)

• Strong: Passw0rd (mix of upper/lowercase and numbers)

• Stronger: P@ssw0rd! (adds symbols)

When creating passwords, always aim to mix in uppercase, lowercase, numbers, and symbols to maximize complexity.

Pro Tip: Substitute characters for complexity

An easy way to build complexity is to substitute numbers and symbols for letters:

• password → p@ssword (substitute @ for a)

• password → p@55w0rd (substitute 5 for s and 0 for o)

Substituting characters adds complexity while keeping passwords somewhat memorable.

Unpredictability

Unpredictability refers to how random or non-obvious a password is to guess. Strong passwords avoid anything related to you personally or that could be found in a dictionary.

Here are some examples of predictable vs. unpredictable passwords:

Predictable

• Your birthday: 08151980
• A pet‘s name: sammy
• Your address: 123MainSt

Unpredictable

• Random string: Ks29$%s1
• Nonsense phrase: Bluerefrigerator88

Unpredictable passwords use random combinations of letters, numbers, and symbols that have no discernable pattern or meaning. This makes them incredibly difficult to guess.

Pro Tip: Generate randomness

An easy way to create unpredictable passwords is to generate random characters. You can use online random password generators or simply mash your keyboard.

Adding a few random characters goes a long way in thwarting predictability.

Uniqueness

Uniqueness means that each of your passwords should be different. Reusing the same password across multiple accounts is dangerous.

If that one password gets compromised anywhere, it jeopardizes the security of all your accounts. Unique passwords prevent this type of crossover vulnerability.

Pro Tip: Use a password manager

It‘s hard to remember tons of unique, complex passwords. That‘s where password managers come in handy. Password managers generate and store strong unique passwords for all your logins.

Leading password managers like 1Password and LastPass make it easy to have different, ultra-secure passwords everywhere without much effort.

So in summary, the four pillars of strong passwords are:

• Length – The longer the better
• Complexity – Mix upper/lower case, numbers, symbols
• Unpredictability – Totally random
• Uniqueness – Different for every account

Now let‘s see how to put these principles into action…

How to Create a Strong Password

When constructing a password, your goal should be maximizing those four attributes above. Here is a step-by-step process:

1. Come Up With a Random Phrase or Sentence

First, think of an unpredictable phrase or sentence that‘s at least 10 words long. Avoid any personal info or dictionary words.

For example:

"Jupiter rings loudly every seventh Monday midnight"

This random 15-word phrase provides great raw material for our password.

2. Take the First Letter From Each Word

Extract just the first letter from each word in your phrase:

"JrlleshmM"

This creates a base password skeleton that preserves the length of your original phrase.

3. Introduce Complexity

Now we modify the password to include uppercase letters, numbers, and symbols:

"JrL7E$hMm@"

Substituting characters makes this password significantly more complex, while still retaining some relation to the original phrase.

4. Add More Random Characters

Finally, insert a few fully random characters into your password:

"JrL7E$hMm@&%xD5#"

These extra characters boost unpredictability.

Our completed password is now 16 characters long with upper/lowercase letters, numbers, symbols, randomness – all the ingredients of a mighty strong password!

Let‘s try another example…

Phrase: "Elephants are afraid of mice"

1. Extract first letters: "Eaamo"

2. Add complexity: "E@a@m0!"

3. Insert random chars: "E@a@m0!#$dQ%"

Once again we‘ve created a superbly strong 16-character password by following our method.

More Examples of Excellent Passwords

Let‘s look at a few more samples of strong passwords generated using the steps above:

Phrase: "There is a city in Russia named Yekaterinburg"

Password: y!I@c1nRn@Y#12kA

Phrase: "The Loggerhead sea turtle can weigh up to 300 pounds"

Password: Tl$tCwUt3kG#

Phrase: "A group of crows is called a murder"

Password: Am0cI@c@Mu%^789

Phrase: "The moon orbits the Earth every 27.3 days approximately"

Password: Tm0tEe2d7#Ap@

These are fantastic examples of lengthy, complex, unpredictable and unique passwords. Even as a cybersecurity expert, I would have an extremely difficult time cracking these in any reasonable timeframe.

Notice that none contain personal info or real words, all use upper/lowercase/numbers/symbols, and all are 16+ random characters.

But the great thing is these passwords are still somewhat rooted in memorable phrases, making them easier for users to recall.

Tips for Strengthening Password Security

Using strong, unique passwords is crucial. But you can also implement these additional practices to further enhance your overall password security:

Use a dedicated password manager

Password managers generate, store and fill passwords for you. This lets you use long, random passwords without having to actually remember them yourself. Leading password managers like Dashlane and 1Password offer robust security features.

Enable two-factor authentication (2FA)

2FA requires you to enter a code from your phone when logging in, on top of your password. So even if your password gets compromised, thieves can‘t access your account without also stealing your phone. Popular 2FA apps include Authy and Google Authenticator.

Change passwords regularly

Periodically changing passwords limits the damage if one does get leaked. Security experts recommend changing passwords for critical accounts every 60-90 days.

Be wary of phishing schemes

Beware of fake login pages that try to steal passwords. Double check web addresses and look for misspellings. Avoid clicking links in emails – instead go directly to sites. These steps thwart phishing scams.

Use a password strength checker

Run your passwords through a strength checking tool to identify weak or reused ones to update. This helps weed out any existing insecure passwords lurking in your digital identity.

Don‘t reuse passwords

I can‘t stress this enough – password reuse is one of the biggest security pitfalls. If one account gets hacked, reusing passwords allows access to your other accounts. Unique passwords are essential.

So in summary, properly constructed passwords combined with multifactor authentication, password managers, and other good practices offer the best protection.

Next let‘s answer some of the most frequently asked questions about creating and managing strong passwords…

FAQs about Strong Passwords

Here are answers to some of the most common questions I receive regarding password security best practices:

How exactly are passwords cracked? What are the main methods?

Hackers predominantly use two methods – guessing and brute forcing. Guessing involves trying common passwords like "123456" or dictionary words. Brute forcing systematically tries every possible password combination through computing power.

What are the most commonly hacked passwords?

Per multiple studies, the most commonly used (and least secure) passwords are:

• 123456
• password
• qwerty
• 12345

Very simple numerical or keyboard patterns like these are easily guessed and cracked.

How long would it take to crack my password?

It depends on computing power, but 8-character passwords could take seconds to crack via brute force. 12-characters could take months. 20+ characters with full complexity may never be cracked. Strong passwords require an impractical amount of time.

Is it bad to write down passwords? Should I just try to remember them?

Physically writing down complex passwords can be safer than trying to remember and reuse weak ones. But for best security, use a password manager app rather than unsecured notes.

Are longer passwords always better than complex ones?

Length and complexity together is ideal. But extra length has an exponential impact on security. A longer, simpler password is harder to crack than a shorter, more complex one. Prioritize length over complexity.

Should I change my passwords frequently? Like every 30 days?

Frequent password changes were once recommended, but are no longer considered beneficial unless there is an indication of compromise. Periodic changes of every 60-90 days for critical accounts is sufficient.

How many unique passwords should I have?

At minimum, you should have unique passwords for your main email account, financial accounts, and any sites containing sensitive information. Other accounts can have slightly more reuse. Shoot for at least 8-10 distinct strong passwords.

What is better for security: passphrases or passwords?

Long passphrases are generally considered stronger than traditional passwords, as length enhances security. Multi-word passphrases also tend to be easier for humans to remember. So passphrases offer advantages.

Which is best for encrypting passwords: AES, RSA, or SHA?

AES is the gold standard – it uses strong symmetric encryption suitable for passwords. RSA and SHA are asymmetric algorithms more suited for encrypting/signing messages. For password hashing, AES is by far the most secure choice.

The Bottom Line

Hopefully this guide has provided you with useful insights and tactics for significantly improving your password security. The key takeaways are:

• Use maximum safe length – 12+ characters is best
• Incorporate all character types – uppercase, lowercase, numbers, symbols
• Randomness is critical – avoid patterns, info, and real words
• Every account should have its own unique password
• Leverage password managers and two-factor authentication
• Change critical passwords every 60-90 days

Implementing strong, unique passwords takes a bit more time upfront. But it provides immense long-term benefits for securing your sensitive data and privacy.

In today‘s era of highly sophisticated cyberattacks, taking password security seriously is more important than ever before. My advice is to start upgrading your passwords using the recommendations in this guide.

Your identity and information are valuable. Secure them properly with robust passwords.
