Password Generator Online: Strong, Random Passwords
A password generator produces random strings that are far harder to guess than anything you would invent by hand. This guide covers what makes a password strong and how to generate one safely.
What makes a password strong
Strength comes from length and unpredictability, not from clever substitutions. A long random string drawn from a large character set has far more entropy than a short "complex" word.
This generator uses the browser cryptographic random source, so the output is unpredictable, and it runs locally — passwords are never transmitted or stored.
Tune length and character sets
Increase length first; it matters most. Add numbers and symbols to expand the character set, or switch to a readable mode that drops ambiguous characters when a human will type the password.
Use a manager
Generate a unique password per account and store it in a password manager. Reuse is the real risk — a single leaked site should never compromise the others.
Preguntas frecuentes
Are the generated passwords stored anywhere?
No. They are generated in your browser and never sent to a server or saved. Copy the one you need into your password manager.
How long should a password be?
Longer is stronger. For most accounts 16 or more random characters is a sound choice; use the maximum a service allows for important accounts.
