🔒 Passwords are generated locally with the Web Crypto API — they never leave your browser.
Generate strong, random passwords
Set length and character types, generate locally, and copy — nothing is transmitted or stored.
Length beats cleverness
A long random string is far harder to attack than a short one with symbol substitutions. Push the length slider first.

Open Strong Password Generator — Free, Online & Secure in your browser, set the length slider (default is 16, range 4–128 characters), check the boxes for Include uppercase, Include lowercase, Include numbers and Include symbols if needed, then click the Generate Password button. The page will show a Password field and a strength meter that reports entropy in bits and an estimated crack time; click Copy to copy to clipboard or Download .txt to save as passwords.txt (UTF-8). If the site prompts for clipboard access, click Allow; on older Safari you may need to manually long-press the field to paste.
Yes — use the Batch Generate panel, set Passwords to create up to 500 entries per run (practical browser limit to avoid freezing), choose length and character options, then click Generate Batch. The tool renders results in a table with Copy All and Download .csv buttons that save a UTF-8 CSV named passwords.csv with columns account,username,password,notes; each row is newline-terminated. For very large exports over 500 rows use desktop Chrome or Firefox to avoid memory spikes; mobile browsers can hang when rendering thousands of rows.
The Include symbols checkbox adds ASCII punctuation characters like ! " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _ ` { | } ~ by default; you can toggle Avoid ambiguous characters to strip similar symbols like | and l. Many websites reject certain symbols or enforce their own allowed set and maximum length, so if a site blocks characters use the Custom charset textbox to specify only allowed characters or generate a password, then use the tool's Replace button to swap disallowed characters. Remember very long passwords with many symbols improve entropy but can break older forms or autofill systems.
After generating one or more passwords use the Download .csv button to produce passwords.csv encoded in UTF-8 with columns account,username,password,notes which 1Password and KeePass will accept on import if you map columns appropriately. For single entries you can Download .txt (passwords.txt) with only the password on the first line; KeePass also accepts tab-delimited .txt if you open it and re-save as .csv. Because Strong Password Generator does not store data server-side, make sure to import or save the file to your password manager and then securely delete the local file if needed.
No signup is required and the generator runs client-side in your browser so passwords are not transmitted to our servers during normal use; the one-line privacy summary appears on the page, but you should still treat exported files carefully. If you use Download .csv or Download .txt the file is created locally in your browser’s download folder (e.g., Downloads/passwords.csv) and remains on your disk until you delete it. For automated workflows consider importing directly into a password manager rather than saving plaintext files to reduce risk, since the site doesn't provide a vault or synchronization.
The strength meter shows estimated entropy in bits and an approximate offline-crack time using a conservative attack rate (displayed like “~10^20 years at 10^10 guesses/sec”), and it highlights which character classes are present. Use the entropy bits to compare (aim for 80+ bits for typical account security, 128+ bits for long-lived keys), but also check real-world constraints: many sites limit length to 64 characters or disallow symbols. The meter is a heuristic — for critical systems use a password manager-generated passphrase or keyfile and follow the site’s accepted rules rather than relying solely on the numeric estimate.
Clipboard writes use navigator.clipboard.writeText and require a secure context (HTTPS) plus a user gesture; if your browser blocks it you’ll get a permissions prompt or an error in the console. On Chrome and Edge click Allow when prompted or use the Copy button; on iOS Safari copy may only work after a direct tap and you might need to manually select and long-press the password field to Copy. If copying still fails use Download .txt or Download .csv as a fallback, or paste into a password manager by manually selecting the text.
Most sites accept 8–64 characters; Strong Password Generator offers 4–128 characters so set between 12–20 for regular accounts, 20–64 for sensitive accounts, and 64–128 for system keys or vault passwords if the site accepts them. Use a mix of uppercase, lowercase, numbers, and symbols for maximum entropy, but check the target site's max length and allowed characters — the tool’s Avoid ambiguous characters option helps with sites that block similar symbols. If a site enforces a maximum of 32 characters, generate within that limit and store the password in a manager instead of memorizing it.
The web app is fully functional on mobile browsers but mobile Safari and some Android WebViews throttle JavaScript memory, so generating large batches (over ~200 passwords) can cause slowdowns or crash the browser; generate smaller batches or use desktop for bulk exports. Clipboard behavior differs: iOS requires a direct tap and sometimes the Share/Copy menu instead of navigator.clipboard, while Android Chrome generally supports Copy button. For enterprise use, prefer desktop Chrome/Firefox for exporting .csv files and then import into your password manager to avoid accidental loss.
Enable the Pronounceable toggle to have the generator produce passphrase-style passwords built from consonant–vowel syllables; you can set Word count between 3–8 (default 4) which yields easier-to-memorize passphrases like “moran-tike-pel”. Pronounceable mode trades some entropy per character compared with full-random symbols, so increase word count (5–7 words) to reach comparable strength for long-term secrets. Use the strength meter to verify entropy and prefer importing the result into your password manager rather than typing it if the string includes unusual hyphenation.
Common issues include clipboard permission denials, browser memory warnings when creating very large batches, and sites rejecting characters generated because of policy; check the browser console for clipboard errors and click Allow or use Download .txt/.csv as workarounds. If the page freezes on bulk generation, reload and reduce batch size to under 200 on mobile or 500 on desktop; for sites that reject symbols, use the Custom charset field to remove problematic characters and regenerate. If the strength meter shows low entropy despite options checked, verify you haven't enabled Pronounceable mode or limited the charset inadvertently.
Strong Password Generator is convenient for one-off or ad-hoc password creation without installation, offers GUI controls (length slider, Include checkboxes, Pronounceable toggle) and immediate exports (.txt/.csv), while KeePass and command-line tools (pwgen, openssl rand) integrate with local vaults and scripts and support automatic insertion and secure keyfiles. The trade-off is that the online tool does not provide vault storage or cross-device sync — after generating you should import passwords into KeePass/1Password or your OS keychain for long-term management. For automation or enterprise policy enforcement prefer desktop/password-manager generation; for quick, no-signup generation this web app is faster.
