Password Generator Online
Create strong, random passwords in one click. Choose the length and character types, check the strength, and copy your password — free, instant, and completely private.
How This Password Generator Works
This generator creates passwords with your browser's built-in secure random number generator (crypto.getRandomValues), the same kind of randomness used by banks and password managers. It picks each character at random from the character sets you select — uppercase letters, lowercase letters, numbers and symbols. Nothing is sent to a server, nothing is stored, and nobody else can see the passwords you generate. You can close the page and the password is gone, so copy it into your password manager or account straight away.
Every setting changes the strength of the result. Length matters most: a 16-character password is enormously harder to guess than an 8-character one, because every extra character multiplies the number of possible combinations. Adding symbols and numbers widens the pool of characters an attacker must try for each position. The strength meter below the results shows the estimated entropy — a measure of how many guesses an attacker would need on average — so you can see the effect of each setting in real time.
What Makes a Password Strong?
- Length — use at least 16 characters. For important accounts such as email and banking, 20 or more is better.
- Randomness — a truly random password beats a clever one. Words, names, dates and keyboard patterns (like qwerty) are the first things attackers try.
- Variety — mix uppercase, lowercase, numbers and symbols so each character can be any of 70+ possibilities.
- Uniqueness — never reuse a password. If one site leaks it, every account sharing it is exposed.
Password Tips — Stay Safe Online
Most hacked accounts are not broken by guessing one password at a time. Attackers use lists of passwords leaked from other websites, try common passwords, and run automated tools that test millions of combinations per second. A short or predictable password falls quickly. A long random one would take centuries to crack with current computers, so attackers move on to easier targets.
Good Habits That Protect You
- Use a password manager — it remembers a different random password for every site, so you only need to remember one strong master password.
- Turn on two-factor authentication (2FA) — even if a password leaks, an attacker still needs the code from your phone or authenticator app.
- Never share passwords — no real company will ever ask for your password by email, chat or phone.
- Change passwords after a breach — if a service you use reports a data breach, change that password immediately, and change it anywhere else you reused it.
- Watch out for look-alike characters — if you need to read a password aloud or type it from paper, tick "Exclude ambiguous" so there is no confusion between l, I, 1, O and 0.
What Not to Do
Do not use your name, birthday, pet's name or favourite team — attackers find these on social media in minutes. Do not use the same password with a number added at the end (password1, password2), because cracking tools try exactly that. And do not store passwords in a plain text file, a note on your phone, or a sticky note on your monitor.
