A strong password is long and random. This tool generates secure passwords using the browser cryptographic random source, with control over length and which character sets to include. Nothing is ever transmitted or stored.
How to use it
- Set the length.
- Toggle uppercase, lowercase, numbers and symbols.
- Click Generate.
- Copy the password.
About Password Generator
The strength of a password comes from its entropy — how many possible combinations an attacker would have to try. Length matters more than complexity rules, and randomness matters most of all, because predictable patterns are the first thing cracking tools try. This generator uses crypto-grade randomness so each password is genuinely unpredictable, and lets you match any site’s character requirements. Generation is entirely local — the password exists only in your browser until you copy it.
FAQ
Is the password sent anywhere?
No. It is generated locally using your browser’s cryptographic random source and never transmitted.
What makes a password strong?
Length and randomness. A long, random password from a large character set is far stronger than a short complex one.
Should I reuse generated passwords?
No. Use a unique password per site, ideally stored in a password manager.
