Password Generator: The Complete Guide
Create a strong, random password in one click. Choose the length and which character types to include, and a secure password is generated right in your browser — never sent anywhere.
Who the Password Generator is for
Anyone who needs a strong, unique password for an account, Wi-Fi, or device.
How to use the Password Generator
- Type your values into the fields above — pick your currency or units where the calculator offers them.
- Results update automatically as you type; there's no submit button and nothing is sent to a server.
- Adjust any input to compare scenarios, then copy the result with a single click.
How it works
Characters are drawn from your selected sets using your browser's cryptographic random generator, guaranteeing at least one of each chosen type, then shuffled. More length and more character types mean higher entropy.
Features
- Adjustable length (4–128)
- Upper, lower, numbers, symbols
- Entropy & strength shown
- Cryptographically random
What makes a password strong?
Strength comes from length and unpredictability, measured in bits of entropy. A long password drawn from a large character pool is exponentially harder to guess than a short one. This generator uses cryptographic randomness in your browser, so each password is unique and never transmitted. Pair it with a password manager to store them.
