Strong Password Generator
Generate 16 to 32 character passwords with uppercase, lowercase, numbers, and symbols always on.
Nothing is stored
Passwords are generated locally with the Web Crypto API. They are never transmitted or saved. Copy the one you want into a password manager before closing this tab.

How to Generate a Strong Password
Pick a length preset. Sixteen characters is the recommended minimum for any account that matters. Twenty is a good default for email and banking. Thirty-two is appropriate for a password manager master password or an encryption key.
Set how many passwords you want. Generating three at once lets you scan the list and pick the one that is easiest to type if you ever need to enter it manually on a phone or TV.
Click Generate, copy the result, and paste it straight into your password manager. Do not retype it, do not email it to yourself, and do not save it in a notes app.
Why Length Beats Complexity
Complexity rules like "must contain one symbol" were designed for eight-character passwords. They add very little strength compared to simply making the password longer.
Each additional character multiplies the search space by the size of the character pool. Going from 12 to 16 characters with the full 94-character set multiplies the number of possibilities by roughly 78 million. Adding one symbol to a 12-character password multiplies it by far less.
This generator holds all four character types on so you satisfy site complexity rules automatically, then lets you push length as high as the site allows. That combination is what makes a password practically uncrackable.
Where Strong Passwords Matter Most
Email. Your inbox can reset the password on nearly every other account you own. It deserves your longest password plus two-factor authentication.
Banking and payments. Financial accounts are targeted by credential stuffing within hours of any public breach. A unique 20-character password makes reused-credential attacks useless.
Password manager master password. This is the one password you must remember. If memorizing a random string is not realistic, use the Memorable Password Generator to build a long passphrase instead.
Cloud storage and work accounts. These often contain documents that reveal answers to security questions on other services, so they need the same protection as email.
Common Strong Password Mistakes
Reusing one strong password everywhere. Strength does not help when a breached site hands attackers the plaintext.
Adding a predictable suffix like a year or an exclamation mark to a familiar word. Cracking tools test those variations first.
Storing passwords in a spreadsheet or browser note. Use a dedicated manager with encryption at rest.
Choosing a shorter password because a site caps the length. If a site limits you to 12 characters, use all 12 with every character type and enable two-factor authentication.
