What Is a Password Generator?
A password generator is a tool that creates random, unpredictable passwords for you. Instead of coming up with something yourself (and probably reusing the same password across multiple sites), a generator produces a unique combination of characters that would take an attacker millions of years to guess.
The problem with human-created passwords is that we tend to fall into patterns. We pick names, birthdays, favorite words, or simple sequences like "123456" or "password." Hackers know this. They run dictionary attacks and pattern-matching algorithms that can crack these kinds of passwords in seconds.
A strong password generator solves this by removing human bias entirely. It pulls from a pool of uppercase letters, lowercase letters, numbers, and symbols to build a string that has no pattern, no meaning, and no connection to your personal information. That is what makes it secure.
Why You Need a Strong Password for Every Account
Data breaches happen every single day. In 2024 alone, billions of credentials were leaked from major platforms. If you are using the same password on multiple sites, a single breach can give attackers access to your email, social media, banking, and everything else tied to that password.
A secure password generator helps you create a different, strong password for each account. When each password is unique and random, a breach on one site does not compromise your other accounts. This is the single most effective thing you can do to protect yourself online.
Think of it this way: you would not use the same key for your house, your car, and your office. Your online accounts deserve the same level of separation. Our free password generator makes it easy to create as many unique passwords as you need, whenever you need them.
How Our Random Password Generator Works
The Webuify password generator runs completely inside your web browser. When you click "Generate Password," the tool uses the Web Crypto API, which is the same cryptographic engine that secures your banking transactions and encrypted communications. This means the randomness is not simulated. It is real, hardware-backed entropy.
Here is how the process works:
1You choose your settings: password type (random, passphrase, or PIN), length, and which character sets to include.
2The tool requests cryptographically secure random bytes from your browser's built-in random number generator.
3Those random bytes are mapped to your selected characters. If you want uppercase, lowercase, numbers, and symbols, the tool pulls from all four pools.
4At least one character from each selected type is guaranteed, then the rest are filled randomly. The entire string is shuffled for extra unpredictability.
5The finished password appears on screen. You copy it, and that is it. Nothing leaves your device.
No server calls, no cookies, no tracking. The password you generate is known only to you. Even we cannot see it.
How Long Should Your Password Be?
Password length is the single biggest factor in password strength. Every extra character multiplies the number of possible combinations an attacker would need to try. Here is a practical breakdown:
Length
Best For
Strength
8 characters
Minimum requirement for most sites
Fair
12 characters
Social media, forums, general accounts
Strong
16 characters
Email, shopping, work accounts
Very Strong
20+ characters
Banking, crypto wallets, master passwords
Excellent
32+ characters
API keys, encryption keys, server passwords
Maximum
Our password generator lets you create passwords anywhere from 4 to 128 characters. For everyday use, we recommend 16 characters as a good balance between security and convenience. If you are using a password manager (which you should), there is no reason not to go longer.
Random Passwords vs. Passphrases: Which Should You Use?
There are two main approaches to creating strong passwords, and our tool supports both.
Random Passwords
Strings like k9$Lm2@xQv!pR7nW that use a mix of all character types. These offer the highest entropy per character, making them the most secure option for a given length.
Maximum security per character
Ideal for password managers
Best for sensitive accounts
Passphrases
Combinations like Falcon-Copper-Bridge-742 that string together random words. These are longer but much easier to type and remember.
Easy to remember and type
Great for master passwords
Recommended by security experts
Both approaches work well when done right. The key difference is convenience. If you are copying and pasting from a password manager, random characters are the way to go because you never need to type them. If you need to manually type a password (like your computer login or your password manager's master password), a passphrase with 4 or more random words gives you strong security with much less friction.
Password Security Tips That Actually Matter
Creating a strong password is just the first step. Here is what you need to do to stay properly protected:
1
Use a unique password for every account
This is not optional. If one account gets compromised, every other account with that same password is at risk. A random password generator makes it painless to create a fresh password each time.
2
Store passwords in a password manager
You cannot realistically memorize 50+ unique, random passwords. A password manager stores them securely behind one master password. Good options include Bitwarden (free and open source), 1Password, and KeePass.
3
Turn on two-factor authentication
Even the strongest password can be compromised through phishing or a server breach. Two-factor authentication adds a second layer so that your password alone is not enough to get in.
4
Never share passwords over email or chat
If someone needs access to a shared account, use a password manager's sharing feature. Messages can be intercepted, forwarded, or stored in logs you do not control.
5
Update passwords after a breach
If a service you use announces a data breach, change that password immediately. If you reused it anywhere (stop doing that), change it there too. Use a password generator to create the replacement.
6
Check if your passwords have been exposed
Services like Have I Been Pwned let you check whether your email or passwords have appeared in known data breaches. If they have, it is time to generate new ones.
Common Password Mistakes People Still Make
Even with all the warnings, millions of people still make the same mistakes with their passwords. Here are the ones that put your accounts at the most risk:
Using personal information
Names, birthdays, pet names, and addresses are the first things attackers try. This information is often publicly available on social media.
Using dictionary words
Passwords like 'sunshine', 'football', or 'dragon' are in every cracking dictionary. Dictionary attacks can test thousands of common words per second.
Simple character substitutions
Swapping 'a' for '@' or 'e' for '3' does not fool modern cracking tools. They test these variations automatically.
Reusing passwords across sites
When one site gets hacked, attackers try those stolen credentials on hundreds of other sites. This is called credential stuffing, and it works surprisingly often.
Making passwords too short
An 8-character password with only lowercase letters has about 200 billion combinations. That sounds like a lot, but modern hardware can crack it in under a minute.
Writing passwords on sticky notes
Physical notes near your computer are visible to anyone who walks by. If you need to write a password down, lock it in a drawer or safe, not on your monitor.
The easiest way to avoid all of these mistakes is to stop creating passwords manually. Let a random password generator handle it, save the result in a password manager, and move on. It takes less time than trying to think up something clever, and the result is exponentially more secure.
What Is Password Entropy and Why Does It Matter?
Entropy is a measure of randomness. In password security, entropy tells you how many guesses an attacker would need to try before cracking your password. It is measured in bits. The higher the number, the harder the password is to crack.
Our password generator shows you the entropy of every password it creates, along with an estimated crack time. This is not a vague "strong" or "weak" label. It is an actual calculation based on the character set and length you selected.
Entropy benchmarks:
Below 28 bitsVery Weak. Can be cracked instantly with basic tools.
28 to 35 bitsWeak. Vulnerable to brute force in minutes to hours.
36 to 59 bitsFair. Enough for low-value accounts, but not ideal.
60 to 79 bitsStrong. Good protection for most personal accounts.
80+ bitsVery Strong. Would take billions of years to crack at 10 billion guesses per second.
A 16-character password using uppercase, lowercase, numbers, and symbols typically has around 105 bits of entropy. That is more than enough for any purpose. Our tool calculates this in real time so you can see exactly where your password stands.
When to Use a Password Generator
You should use a password generator any time you need to create a new password. But here are some specific situations where it is especially important:
Signing up for a new account on any website or app
Replacing a password after a data breach notification
Setting up your email, banking, or financial accounts
Creating a master password for your password manager
Generating API keys or database passwords for development work
Setting up Wi-Fi passwords for your home or office network
Creating temporary passwords for shared or guest accounts
Generating multiple passwords in bulk for a team or organization
Our tool handles all of these scenarios. Need a quick 12-character password for a new forum? Done. Need 50 complex passwords for a company rollout? Use the bulk generator. Need a memorable passphrase for your laptop login? Switch to passphrase mode. It is all built in.
