Free Online Passwords
Generate random passwords combining uppercase letters, lowercase letters, numbers and symbols, at whatever length you choose. A strength meter instantly shows whether the generated password is weak, medium or strong based on its length and the variety of characters it includes. Generation uses the browser's cryptographic random number generator (Web Crypto API), not a simple pseudorandom generator.

Questions about Passwords
How secure is the generated password?
It depends on the length and character types you enable — for maximum security, use at least 12-16 characters with uppercase, lowercase, numbers and symbols all turned on.
How does the strength meter work?
It evaluates the password's length and how many distinct character types it includes (uppercase, lowercase, numbers, symbols) to rate it as weak, medium or strong.
Is the generated password stored or sent to a server?
No, it's generated entirely in your browser and never stored anywhere. If you close the page without copying it, it's lost.
Do I need to enable every character type?
It's not required, but combining all four types (uppercase, lowercase, numbers and symbols) produces passwords that are harder to guess than using just one or two types.
