Generate strong, random passwords locally in your browser.
Was this tool useful?
Does this password generator upload my passwords to any server?
No. All password generation happens entirely inside your browser using crypto.getRandomValues when available. Nothing is stored, uploaded, or logged.
Why must I choose at least one character set?
The generator needs at least one category (lowercase, uppercase, numbers, or symbols) to build a secure character pool. Without it, a password cannot be generated.
What does 'Avoid ambiguous characters' mean?
This removes characters that can look similar, such as O, 0, l, 1, and |. Enabling the option makes passwords easier to read and type without reducing security significantly.
Why is the minimum password length 4?
Shorter passwords are extremely insecure. The tool enforces a lower limit of 4 characters and a maximum of 128 to maintain strong randomness and performance.
Why can I generate up to 200 passwords at once?
Generating many passwords is fast in the browser. The limit of 200 prevents UI slowdown and accidental creation of extremely large output blocks.
Why do all passwords contain at least one character from each selected set?
To ensure stronger security, the generator forces each selected category (lower/upper/numbers/symbols) to appear at least once. The rest is filled with random characters.
Why does adding a prefix or suffix change the strength?
Prefixes and suffixes are appended after generating the secure random part. They are counted in the final length and may slightly reduce randomness if predictable.
Why do passwords appear in random order each time?
After generation, all characters are shuffled using a Fisher–Yates shuffle. This ensures maximum randomness and prevents predictable placements.
Can I copy or download all generated passwords?
Yes. The tool supports copying the entire list to your clipboard and downloading them as a .txt file.
Is this tool safe for generating production API keys or critical secrets?
While secure for general use, highly sensitive production secrets should always be generated using your platform’s official secret management tools.
