Bulk Password Generation
What Is a Password Generator?
A password generator is a tool that creates random, strong passwords using a mix of characters you choose. It removes the human bias from password creation so every password is truly unpredictable and hard to crack. This tool generates passwords entirely in your browser and never transmits them to any server.
When you create a password yourself, you tend to use patterns you can remember, birthdays, names, favourite words. Attackers know this and exploit it. A password generator removes that bias entirely. Every character is chosen by a cryptographically random algorithm, producing passwords that are genuinely unpredictable even to the tool that made them.
Our generator supports three modes: random passwords for maximum security, memorable passphrases for accounts you need to type regularly, and numeric PINs for devices and cards. You can also generate up to 100 passwords at once using the bulk option above.
What Makes a Strong Password in 2026?
A strong password in 2026 is at least 16 characters long, uses a mix of uppercase letters, lowercase letters, numbers, and symbols, is completely unique to one account, and was not created by a human typing familiar words or patterns.
The rules have shifted significantly. In 2024 the National Institute of Standards and Technology (NIST) updated its password guidelines to clarify that length matters far more than complexity. A 16-character password of mixed types is dramatically stronger than an 8-character password loaded with symbols.
Here is the practical impact of length on crack time, based on current GPU attack speeds:
| Password Length | Character Types | Time to Crack (2026 GPU) | Recommendation |
|---|---|---|---|
| 8 characters | Numbers only | 25 seconds | Never use |
| 8 characters | Mixed (upper + lower + nums + symbols) | 39 minutes | Avoid |
| 12 characters | Mixed | 34,000 years | Minimum |
| 16 characters | Mixed | 34 billion years | Recommended |
| 20 characters | Mixed | Longer than the universe | Ideal |
The takeaway: use 16 characters as your default and enable all character types. The tool above defaults to 16 characters with uppercase, lowercase, numbers, and symbols for exactly this reason.
How to Use This Password Generator
Using the tool takes under 30 seconds. Here is the process step by step.
- Choose a password type using the tabs at the top. Random gives you maximum security. Memorable creates a passphrase of real words. PIN creates a number-only code.
- Set your length using the slider. For most accounts, 16 is the right default. For very sensitive accounts like email and banking, use 20 or more.
- Toggle character types on or off. Leave all four types on for maximum strength. Toggle "Exclude Ambiguous" on if you need to type the password manually.
- Click Generate Password. A new password appears instantly and the strength meter updates in real time.
- Copy and use it. Click the yellow Copy button, then paste it directly into your account. Save it in a password manager before you leave this page.
Important: This tool generates passwords entirely in your browser using JavaScript's cryptographic random number generator. Nothing is sent to any server. Nothing is logged or stored anywhere. Once you close the tab, the password is gone. Save it in a password manager before you do.
Random vs Memorable vs PIN - Which Should You Choose?
Random passwords
Random passwords are the strongest option. They combine upper and lowercase letters, numbers, and symbols in a completely unpredictable sequence. Use these for your email account, bank accounts, cloud storage, and any other account that holds sensitive data. They are hard to type manually, so use a password manager to store and autofill them.
Memorable passphrases
Memorable passphrases combine several random words into a phrase you can actually type and remember. An example would be something like "tunnel-magnet-silk-oxygen". Despite looking simpler than a string of symbols, a four-word passphrase is cryptographically stronger than most 10-character random passwords because of its length. Use these for your password manager master password or your laptop login, where you need to type it regularly without autofill.
PIN codes
PINs are for devices, cards, and applications that only accept numbers. A 6-digit PIN is fine for most phone lock screens. A 4-digit PIN is the minimum acceptable for ATM cards. For app-based PINs where you can choose the length, go with 8 digits or more.
Why You Should Never Reuse Passwords
Reusing passwords is the single biggest reason ordinary people get hacked. Here is exactly how it happens.
A company you have an account with gets breached. Your email address and password are leaked in that breach. Attackers then take those credentials and try them on hundreds of other websites automatically. This is called credential stuffing. If you reused that same password for your email, bank, or social media, every one of those accounts is now at risk from a single breach that had nothing to do with you.
According to Verizon's Data Breach Investigations Report, over 80% of hacking-related breaches involve stolen or weak credentials. Using a unique password for every account is the single most effective thing you can do to protect yourself online. The only practical way to do this is with a password manager.
What to Do After Generating a Password
A strong password only protects you if you store and use it correctly. Follow these steps every time you generate a new password.
- Save it in a password manager immediately. Do not rely on your browser's built-in password saving for important accounts. Use a dedicated password manager like Bitwarden (free), 1Password, or Proton Pass.
- Enable two-factor authentication (2FA). A strong password plus 2FA means an attacker needs both your password and physical access to your phone. This combination defeats most automated attacks completely.
- Never write it down in plain text. Do not paste passwords into notes apps, emails, or text messages where they could be read by others or synced to insecure locations.
- Use a different password for every account. If one account is compromised, every other account stays safe.
- Do not share passwords. If someone else needs access to a shared account, use the sharing feature in a password manager rather than sending the password in a message.
Is a Password Generator Safe to Use?
Yes, when a generator runs entirely in your browser and does not transmit passwords to a server. Our generator creates passwords using JavaScript's cryptographic random number generator (window.crypto.getRandomValues) and never sends any data outside your device.
The key safety question for any password generator is: where does the generation happen? Tools that send your settings to a server and receive a password back are fundamentally less trustworthy because the server could theoretically log what was generated. Our tool generates everything client-side. The code is in the page you loaded and runs only on your device.
The only remaining risk is your own device. Make sure you are using a private, secure connection and not on a device that is infected with malware or a keylogger when using generated passwords for very sensitive accounts.
