Password Generator
Create strong random passwords in your browser — nothing is sent anywhere or stored.
What is this tool?
The average American juggles close to 100 online accounts, and reused, guessable passwords are the top cause of account takeovers. This password generator creates genuinely random passwords using your browser's cryptographic random number generator — the same secure source your operating system uses — so every password is unpredictable, unique and generated entirely on your device.
Length beats complexity tricks: a 16-character random password is far stronger than 'Password1!' and modern guidance from NIST encourages long passphrases and password managers instead of forced rotations. Generate a password here, save it in a reputable password manager (or your browser's built-in one), and never reuse it on a second site.
How to use it
- Set the length — 16 characters or more is a good default.
- Choose which character sets to include: uppercase, numbers and symbols.
- Click Generate for a fresh password, then copy it straight into your password manager.
Formula & method
Worked example
A 16-character password with uppercase, lowercase, digits and symbols has roughly 6.5 quadrillion times more combinations than an 8-character lowercase-only password. At a billion guesses per second, the short one falls in minutes; the long one would take longer than the age of the universe.
Frequently asked questions
How long should a password be?
At least 16 characters for important accounts like email and banking. Length matters more than exotic symbols, and a password manager makes long passwords effortless.
Are passwords generated here stored or sent anywhere?
No. Generation happens with JavaScript in your own browser. The password never travels over the network and is not logged or saved by this site.
Should every account have a different password?
Yes. When one site is breached, attackers try the leaked email and password on banking and email sites automatically. Unique passwords confine the damage to that one account.
