How to Create a Strong Password
Updated 2026-07-04 · By the MakeToolz team
Quick answer: To create a strong password, use at least 16 characters with numbers and symbols, or chain four random words together. Length beats complexity. The safest choice is a random one from a password generator, saved in a password manager.
A good password is long, random, and used on only one site. The rest of this guide explains why those three rules matter and how to hit all of them without memorizing gibberish.
What makes a password strong?
Two things: length and randomness. A long password has far more possible combinations, so a computer trying to guess it takes much longer. A random password cannot be worked out from your name, your birthday, or your favorite team.
Short and personal is weak. Long and random is strong. An attacker's software can test billions of guesses fast, so anything predictable falls quickly. Every extra character and every unpredictable choice slows that machine down.
Length beats symbols
Most advice pushes symbols and capital letters. Length matters more. Each extra character multiplies the number of guesses an attacker needs, which grows the total far faster than swapping in a symbol does.
A 20-character password is far harder to break than an 8-character one, even when the short one is stuffed with symbols. Aim for 16 characters or more on anything that matters, like email, banking, and your password manager itself. Your email is the master key, because most password resets go there.
Why one long password beats many rules
Old rules forced a symbol, a number, and a capital letter. People responded with predictable tricks like a capital at the start and a "1!" at the end. Attackers learned those patterns. A long, random string skips the pattern problem entirely.
The four random words trick
Want something you can actually remember? Pick four random, unrelated words and join them, like copper-tiger-lunar-basket. It is long, easy to recall, and hard to guess. The key word is random. Do not use a famous phrase or a song lyric, because those show up in attacker word lists.
This works because length wins. Four real words make a passphrase over 20 characters long, which is very strong, while still being something your brain can hold. Use this style for the handful of passwords you type by hand.
What to avoid
- Names, birthdays, and pet names. These are easy to find on social media.
- Common passwords like
123456orpassword. These are guessed first. - Simple swaps like
P@ssw0rd. Attackers know every trick for turning letters into symbols. - Keyboard walks like
qwertyorasdfgh. Software checks these instantly. - The same password on more than one site.
That last one matters most. If one site leaks its passwords, attackers try the same email and password on banks, email, and shopping sites. This is called credential stuffing, and it works because so many people reuse passwords.
Let a password manager do the work
You cannot remember a unique 16-character password for 100 sites, and you do not have to. A password manager creates and stores them for you. You remember one strong master password, and it handles the rest, filling logins in automatically.
To make each one, use our free Password Generator. It builds truly random passwords right in your browser, so they never touch a server. Copy the result straight into your manager and move on.
Add two-factor for the accounts that matter
A strong password is the first lock. Two-factor authentication is the second. It asks for a code from your phone or an app after you type the password, so a stolen password alone is not enough to get in. Turn it on for email, banking, and your password manager at the very least.
People Also Ask
How long should a password be?
At least 16 characters for important accounts, and longer is better. Length adds security faster than adding symbols does. For a passphrase, four or more random words gets you there while staying easy to remember.
Are random passwords safe to use?
Yes, as long as you store them in a password manager instead of trying to memorize each one. The generator builds them on your device, so they are never sent anywhere. A random password is the hardest kind for an attacker to guess.
Is a passphrase as good as a random password?
A four-word passphrase is strong and easy to remember. A fully random password is stronger, character for character. Use a passphrase for logins you type often, like your master password, and random passwords for everything else.
How often should I change my password?
Only when a site is breached or you think someone knows it. Forced monthly changes push people toward weak, predictable patterns, so security experts no longer recommend them. Change it fast when there is a real reason, not on a calendar.
What is the most common password mistake?
Reusing the same password across sites. One leak then exposes every account that shares it. A password manager fixes this by giving every site its own unique password with no effort on your part.
Can I trust a password manager with all my logins?
Yes. A good manager encrypts your data so even the company cannot read it. The risk of reusing weak passwords is far greater than the risk of a well-built manager. Just protect it with a strong master password and two-factor authentication.
How do hackers actually crack passwords?
They rarely guess by hand. Software runs through word lists, common passwords, and known leaks at high speed, then tries random combinations. Length and randomness make that search take so long it is not worth the effort.
Should my phone PIN follow the same rules?
A PIN is different because a phone limits how many wrong tries you get. Even so, avoid obvious codes like 1234 or your birth year. A six-digit PIN is much safer than four, and a full passcode is safer still.
