Strong Password Generator Online
Runs 100% in your browser — your files never leave your device.
Reused passwords are how most accounts get breached; a long random one per account is the cheapest defense. Pick the length, choose the character sets, skip look-alike characters if you will ever read the password aloud, and generate. Randomness comes from your browser's cryptographic API — nothing is stored or sent anywhere.
How it works
- 1
Set length and character sets
Slide the length from 4 to 128 and toggle uppercase, lowercase, digits, symbols.
- 2
Generate
One click produces a password guaranteed to use every enabled set.
- 3
Copy it straight away
Copy the password into your password manager — it is never stored here.
