Create secure passwords instantly with custom settings.
Includes "Exclude Ambiguous Characters" and Real-time Strength Check.
100% Client-side processing (No server upload).
This password generator runs entirely within your browser using JavaScript. When you click "Generate", the password is created locally on your device. It is never uploaded or transmitted over the internet to our servers.
It works even if you are offline, making it a secure choice for generating sensitive credentials.
With modern computing power, short passwords (8 chars) can be cracked quickly. We recommend setting the length to at least 12 characters, ideally 14 or more.
Combining "Uppercase", "Lowercase", "Numbers", and "Symbols" exponentially increases the number of possible combinations, making brute-force attacks much harder.
Even the strongest password is useless if it leaks from one site. If you reuse it, all your accounts are at risk. Always use unique passwords for every service.
A. No. The generation process happens solely on your device (Client-side). It is technically impossible for us to see or store your passwords.
A. These are characters that look very similar, such as the uppercase "I" (Eye), lowercase "l" (El), and number "1". Or the uppercase "O" and number "0". Excluding them helps prevent typing errors.
A. Modern standards (like NIST guidelines) suggest not changing passwords arbitrarily unless there is a sign of a breach. Forcing frequent changes often leads to people choosing weaker, predictable passwords.
Generate a random password in seconds and understand what makes it hard to crack.
Each character is picked with your browser's cryptographically secure random number generator (the Web Crypto API), so the result is unpredictable and is never sent over the internet.
Password strength is often measured in bits of entropy: the number of guesses an attacker would need to try every possibility. Each extra character multiplies that number, which is why length matters more than anything else.
| Length | Lowercase + numbers (36 characters) | All four types (88 characters) |
|---|---|---|
| 8 characters | About 41 bits – weak | About 52 bits – weak |
| 12 characters | About 62 bits – fair | About 78 bits – strong |
| 16 characters | About 83 bits – strong | About 103 bits – very strong |
| 20 characters | About 103 bits – very strong | About 129 bits – extremely strong |
A random 16-character password with all four character types is far beyond what brute-force attacks can realistically guess. Human-made passwords like Summer2025! are much weaker than their length suggests, because attackers try common words, names, dates, and patterns first.
Yes. It uses crypto.getRandomValues(), the cryptographically secure random number generator built into modern browsers, and picks every character without bias.
Use at least 12 characters, and 16 or more for important accounts. Current NIST guidance favors long passwords over complex rules or frequent forced changes.
No. The password exists only on your screen until you copy it. Nothing is stored or sent to a server, and the page keeps working even if you go offline after it loads.
When symbols are on, it can use ! @ # $ % ^ & * ( ) _ + - = [ ] { } | ; : , . < > ?. If a website rejects a symbol, generate a new password or turn symbols off and make it longer.
A passphrase of five or more random words is easier to remember and can be very strong, which makes it a good choice for a master password. For everything stored in a password manager, a long random password is the simplest option.
It looks at the length and how many character types the password contains. Treat it as a quick guide; a longer random password is always the safer choice.
