How this password generator stays private

Your browser creates every password on this page with the Web Crypto API. The generator uses crypto.getRandomValues() and rejection sampling, which avoids favoring some characters over others when a random number is mapped to the selected alphabet. The generated value is never placed in the page URL, sent to our server, or saved in browser storage.

Password or passphrase?

Choose a random password when a password manager can save it for you or when a site has strict character rules. Choose a random passphrase when you need something longer that is easier to type or remember.

What the entropy number means

Generated entropy measures the number of equally likely outputs created by the selected length and character alphabet. It describes this generator's process—not the strength of a password a person invented or reused elsewhere.

How to Create a Strong Password

A strong password is long, random, unique to one account, and stored safely. Use the generator above when a password manager can save the result for you. Choose a random passphrase when you need something easier to type or remember.

Make it long and random

Start with at least 15 characters when the service allows it. Random generation avoids names, dates, keyboard paths, and other human patterns that attackers test early.

Use it once

Give every account a different password. Reuse allows a password stolen from one company to unlock accounts elsewhere.

Store it safely

Save generated credentials in a trusted password manager instead of an unencrypted note, spreadsheet, screenshot, or message.

Add another factor

Enable multifactor authentication or a passkey when available. Password length cannot prevent every phishing or malware attack.

Choose the Right Kind of Password

Random password

Best when a password manager can store it or a website has exact character rules. Use the generator above for a customizable, machine-generated value.

Random passphrase

Best when you must type or remember the credential. Use independently selected words rather than a quotation or personal phrase.

Frequently Asked Questions

Why are strong passwords important?
A long, random password is harder to guess, while a unique password prevents a credential stolen from one service from unlocking your other accounts.
What are some guidelines for creating strong passwords?
Use at least 15 characters when the service allows it, generate the value randomly, and use it for only one account. Store it in a trusted password manager, or use a randomly generated multi-word passphrase when you must type or remember it.
Should I use the same password for multiple accounts?
No. Reuse allows a password exposed by one service to be tried against your email, financial, social, and other accounts. Generate a different password for every account.
How can I generate secure passwords?
Use the browser generator on this page or a trusted password manager. This page uses the Web Crypto API to create the value locally and does not send, store, or place the generated password in the page URL.
What additional measures can I take to protect my passwords?
Use a password manager, enable multifactor authentication or a passkey, and replace any password that is exposed, compromised, shared, or reused. Routine calendar-based changes are less important than responding to actual exposure.
