Password Generator
Generate strong random passwords with customizable length and character sets: uppercase, lowercase, numbers, symbols. No data leaves your browser.
About this tool
This password generator creates strong random passwords with cryptographically secure randomness, entirely in your browser. Set the length and choose which character classes to include — uppercase, lowercase, numbers and symbols — then generate one password or four alternatives at once.
Long and unique is the modern rule: a 16-character mixed password is effectively unbreakable by brute force. The copy button puts it on your clipboard in one click, so the next template screenshot or account setup takes seconds.
FAQ
How strong is a 16-character password?
With all character types it has roughly 100+ bits of entropy — practically unbreakable by brute force for centuries.
Does this generator store passwords?
No. Generation happens locally in your browser with cryptographically secure randomness. Nothing is saved or transmitted.
How often should I change a password?
Only when there is a sign of compromise. A long unique password per service is more effective than frequent changes.
