Password Generator
Generate strong, random passwords locally — with a live strength meter and full control over length and characters.
About this tool
The most common way accounts get compromised isn't sophisticated hacking — it's weak and reused passwords. A password like “Rahul@1995” takes modern cracking hardware seconds; a random 16-character password from this generator would take longer than the age of the universe.
This generator uses your browser's cryptographically secure random source (crypto.getRandomValues) — the same class of randomness used in encryption — never the predictable Math.random() that toy generators rely on. Choose a length from 8 to 64 characters and toggle uppercase, lowercase, numbers and symbols. The strength meter updates live, calculated from real entropy (length × character-set size), not a cosmetic guess.
Most importantly: generation happens entirely on your device. The password is never transmitted, never logged, and never stored — it exists only on your screen until you copy it. Close the tab and it's gone. That's a fundamentally stronger privacy model than any generator that touches a server. For best results, use a unique password per account and store them in a password manager rather than reusing even a strong one.
How to use the Password Generator
- 1A strong password is generated the moment the page loads.
- 2Drag the length slider — 16 characters or more is recommended for important accounts.
- 3Toggle character sets on or off. More variety means higher strength.
- 4Click the refresh button for a new password, then Copy to use it.
Frequently asked questions
Is this password generator safe to use?
Yes. Passwords are generated on your device using crypto.getRandomValues, the browser's cryptographically secure random number source. Nothing is sent to a server, nothing is logged, and the password disappears when you leave the page.
How long should my password be?
16 characters with all character sets enabled is a strong default for important accounts, giving roughly 100 bits of entropy. For critical accounts like email and banking, 20+ characters costs nothing extra when a password manager remembers it for you.
How does the strength meter work?
It calculates entropy: password length × log₂ of the character-pool size. A 16-character password drawn from 91 possible characters has about 104 bits of entropy — far beyond what any current hardware can brute-force.
Should I use symbols in my passwords?
Generally yes — they enlarge the character pool and raise entropy. A rare site rejects certain symbols; if that happens, turn symbols off and add a few extra characters of length instead, which more than compensates.
Is it safe to copy passwords to the clipboard?
For most people, yes, briefly. Paste it into the signup form or your password manager promptly, then copy something else — clipboard contents can be read by other apps on some systems. Ideally, store it in a password manager immediately.
