Bulk passwords
Generate strong passwords without sending them online
Reused or short passwords remain one of the easiest ways accounts get breached. The ITCOH Password Generator creates strong random passwords or memorable passphrases entirely in your browser. Adjust length and character sets, check the strength meter, copy once, or bulk-generate a list — without posting secrets to a remote API.
What it offers. Random mode builds strings from the character classes you enable (upper, lower, digits, symbols) with a length slider suited to modern sites. Passphrase mode combines words into something easier to type yet still high entropy. A strength meter gives quick feedback. Bulk generate helps when you are provisioning many test accounts or rotating a set of credentials offline.
Why generate locally. Any “password generator website” that phones home could log the password it just showed you. Even reputable services add unnecessary trust. Cryptographically suitable randomness from window.crypto.getRandomValues (or equivalent browser APIs used by the page) keeps generation on-device. You see the password; we never do.
Privacy proof. Create a password with DevTools Network open — there should be no request carrying the generated string. Prefer copying into a password manager rather than chat apps or email. Clear the page or refresh after you save the credential if you share the device.
Good practices. Prefer unique passwords per site; 16+ characters for random secrets on important accounts; store them in a reputable password manager; enable MFA where available. Passphrases help when a site is hard to paste into. Avoid inventing “clever” patterns based on pet names or birthdays.
Limitations. This tool does not store, sync, or autofill passwords — it only generates. It cannot know if a site bans symbols or caps length; always check the site’s rules. Strength meters are heuristics, not guarantees against every attack model. Passphrase word lists are finite; longer phrases are safer. We do not check passwords against breach corpora here. After generating, you are responsible for storing the secret safely.
Pick a mode above, generate, copy, and save it in your manager. Nothing leaves your browser.
Threat basics (short). Attackers try stolen password lists, guessing common patterns, and stuffing credentials across sites. A unique high-entropy secret per account stops most stuffing. Generating that secret offline removes the generator website from your trust chain. After you copy a password, paste it into your manager immediately and avoid leaving it visible on a shared screen.
Whether you prefer a 20-character random string or a five-word passphrase, keep the generation step local. This page exists so you never have to ask a remote API to invent a secret on your behalf.
Frequently asked questions
Does ITCOH save the passwords I generate?
No. Generation happens in your browser. We do not receive or store the passwords shown on screen.
Random password or passphrase — which is better?
Both can be strong. Random strings maximize entropy for a given length; passphrases are often easier to type. Use a password manager either way.
Is the strength meter perfect?
It is a helpful heuristic, not a formal security proof. Prefer longer unique secrets plus MFA.
Can I generate many passwords at once?
Yes. Use bulk generate when you need a list for offline rotation or test accounts.
Should I email myself a new password?
No. Copy it into a password manager or another secure channel. Avoid chat and email for secrets.
