What is Password Generator?
Password Generator creates strong, random passwords that are hard to guess and easy to regenerate. Choose a length, decide which character types to include, optionally strip out look-alike characters, and produce one password or a whole batch at once. Every password is drawn with your browser's built-in cryptographic random number generator, so nothing is predictable and nothing is ever sent to a server.
How to use Password Generator
Set the length
Drag the Length slider anywhere from 4 to 64 characters. Longer passwords are exponentially harder to crack — 16 characters or more is a good baseline for important accounts.
Choose character types
Toggle uppercase, lowercase, numbers, and symbols on or off. Mixing all four maximises the character pool and the resulting strength. You need at least one type enabled.
Avoid look-alikes if needed
Turn on Exclude ambiguous to drop characters that are easy to confuse — 0, O, 1, l, and I — which is handy when a password has to be typed or read aloud.
Generate one or many
Use the How many slider to create up to 50 passwords in a single batch, perfect for setting up multiple accounts. The output refreshes automatically as you change options.
Copy or regenerate
Watch the strength meter and entropy estimate, then click Copy (or Copy all) to grab the results, or Regenerate for a fresh set that uses the same rules.
