Password Generator
Create strong, random passwords with custom settings.
What makes a password strong
Password strength mainly depends on two factors: length and randomness (entropy). A long password (14 characters or more) with uppercase, lowercase, numbers, and symbols is exponentially harder to brute-force than a short password, even if the short one looks "complex" at first glance.
This generator uses the browser's crypto.getRandomValues API, which produces cryptographically random numbers — unlike Math.random(), which is not safe for cryptographic purposes and can, in theory, be predictable. All generation happens locally in your browser; no generated password is sent or stored on any server.
Frequently asked questions
What is the ideal password length?
At least 12 to 14 characters is recommended. The longer the password, the exponentially longer it takes to crack through brute force, even with the fastest computers currently available.
Are generated passwords saved anywhere?
No. Generation happens entirely in your browser using the crypto.getRandomValues API, and no password is sent, logged, or stored on any server.
Why should I use symbols and numbers in my password?
Each additional character type (lowercase, uppercase, numbers, symbols) increases the number of possible combinations, raising the password's entropy and making brute-force attacks much slower.
