The HN Solutions Password Generator creates strong, random, and secure passwords using your browser’s built-in cryptographic engine. Choose your length and character types — uppercase, lowercase, numbers and symbols — and get an unguessable password instantly, with a live strength and entropy estimate.
Why our password generator is better
- Truly random — built on the Web Crypto API, not a predictable formula a hacker could reverse.
- 100% private — passwords are generated on your device and are never sent or stored anywhere.
- Fully customisable length from 6 to 64 characters and any mix of character sets.
- Shows real strength and entropy so you know exactly how secure your password is.
- Free, no sign-up, and no limits.
How to generate a strong password
- Set your preferred length with the slider.
- Choose which character types to include.
- Click Generate, then Copy your new password.
Frequently asked questions
What makes a password strong?
Length and randomness. A password of 16 or more characters that mixes upper case, lower case, numbers and symbols is extremely hard to crack.
Are these passwords safe to use?
Yes. They are generated locally with a cryptographically secure random source and are never transmitted or saved.
Is the password generator free?
Yes, completely free with no account and no limits.
How long should my password be?
Aim for at least 16 characters and use a unique password for every account.
Does this tool store my passwords?
No. Once you close the page the password is gone, so copy it into a trusted password manager.

What actually makes a password strong
Length, far more than complexity. Each additional character multiplies the number of possibilities; swapping an a for an @ barely changes anything, because attackers’ tools try those substitutions first.
Current guidance from NIST reflects this: it recommends allowing long passphrases, dropping forced complexity rules, and abandoning mandatory periodic expiry — because forcing people to change a password every 90 days produces Summer2026! followed by Autumn2026!, which is worse than leaving a strong one alone.
Why random beats clever
A password you invented follows patterns you are not aware of: a capital at the front, a number at the end, a word that means something to you. Cracking tools model exactly those habits.
Randomly generated characters have no pattern to model, which is why 16 random characters is stronger than a 20-character sentence about your dog. The trade-off is that you cannot remember it — which is fine, because you should not be trying to.
Use a password manager, and the three you must remember
Generating strong passwords only helps if you use a different one everywhere, and nobody can memorise fifty. A password manager solves that properly.
You then need to remember exactly three things: the manager’s master password, your email password, and your device unlock. Make those three long passphrases — four or five unrelated words are both strong and memorable. Everything else can be random noise you never see.
Reuse is the actual risk
Most accounts are not lost to someone guessing a password. They are lost to credential stuffing: a breach at one site exposes an email and password, and attackers try that pair everywhere else automatically.
A unique password per site contains the damage to one account. It is a bigger security gain than any amount of character-set fiddling. Have I Been Pwned will tell you whether an address of yours already appears in a known breach.
Two-factor matters more than password length
A strong password with 2FA enabled beats a stronger password without it, comfortably. An app-based code or hardware key means a stolen password alone is not enough.
Where possible use an authenticator app rather than SMS — SIM-swap attacks are real and text messages are the weakest of the common options.
Generated on your device
Passwords are produced in your browser using the platform’s cryptographic random number generator. Nothing is transmitted and nothing is logged — we could not see what you generated even if we wanted to. Related: the QR code generator and Base64 encoder, both browser-only.
