Password Generator

It depends how it works. This one generates the password locally in your browser using crypto.getRandomValues — nothing is sent to any server, so there is nothing for anyone to intercept or log. Avoid generators that create passwords server-side, since you can't verify they aren't stored.

16 characters is a solid default for anything important; 12 is a reasonable minimum for low-value accounts. Length matters more than symbols: every added character multiplies the cracking effort by the size of the character set. Password managers make long passwords painless since you never type them.

Entropy measures unpredictability in bits: entropy = length × log₂(character-set size). Each additional bit doubles the guesses an attacker needs. Rough guide: under 40 bits is weak, 60–75 is decent, 75+ is strong, 100+ is effectively uncrackable by brute force.

Both can be strong. A truly random 16-character password (~100 bits) beats a 4-word passphrase (~50 bits with common word lists). But a 6–7 word random passphrase is comparably strong and far easier to memorise. Best practice: passphrase for the few passwords you must remember (laptop, password manager), random strings for everything stored in the manager.

Because breaches leak passwords in bulk, and attackers immediately try each leaked email+password pair on other services ('credential stuffing'). One reused password turns a minor forum breach into a compromised email, bank, and social media account. Unique passwords contain the damage to one site.

No — it's one of the first patterns cracking tools try. Substitutions like @ for a and 0 for o are built into every cracking dictionary, as are years, names, and keyboard walks like qwerty. Character variety only helps when the characters are randomly chosen.

Mostly offline: they steal a database of password hashes, then run billions of guesses per second against it using GPUs — starting with leaked-password lists, dictionary words, and known patterns. Truly random passwords force them into raw brute force, which becomes hopeless past ~75 bits of entropy.

Only if you'll ever read or type the password manually — for example a WiFi key printed for guests. Excluding look-alikes slightly reduces entropy (a few bits at most), which you can offset by adding one or two characters of length.

A password manager (Bitwarden, 1Password, KeePass, or your browser's built-in manager). It encrypts everything behind one master passphrase, autofills so you don't type passwords into the wrong site, and makes unique-password-per-account practical. Writing passwords in a notes app or spreadsheet is the thing to avoid.

Current guidance (NIST) says: don't change them on a schedule — change them when there's a reason: a breach notification, a shared password, a suspicious login. Forced periodic changes push people toward weak patterns like Password1, Password2. A unique random password can live until compromised.

No. The password is produced by JavaScript running on your own device using the browser's cryptographic randomness API. It never leaves your machine — there's no server call, no analytics event, no storage. Refreshing the page destroys it permanently, so copy it to your password manager first.

2FA adds a second proof (code, app prompt, hardware key) on top of your password — turn it on for email, banking and anything important. You still need a strong unique password: 2FA can be phished or bypassed in some setups, and many services still allow password-only fallbacks like account recovery.
