Password Generator — strong random passwords

How to use Password Generator

Set the length first — longer is stronger, and everything else is secondary. Then decide which characters to allow: letters, digits, symbols. Some sites reject symbols; when that happens, generate again with them switched off rather than editing by hand, because a human "fix" tends to make the result guessable. Copy, paste, store it in a password manager, and make a fresh one for the next account — reuse is the habit this tool exists to break.

What makes a password generator strong

Humans are terrible at randomness: we reach for birthdays, pet names, keyboard rows, and the word "password" with a digit bolted on. A machine draws every character independently, so the output has no story, no pattern, and no shortcut for an attacker to exploit. The arithmetic needs no calculator to appreciate: each added character multiplies the number of possibilities, so a little extra length buys more safety than any clever swap of letters for symbols ever will.

Digits, PINs, and the four-digit trap

A four-digit PIN drawn from digits alone has ten thousand possible values — fine for a bank card that locks after a few wrong tries, hopeless for anything exposed to the open internet. If a site restricts you to digits, make the number as long as it allows. And when you need random digits for something other than a password — a raffle, a pick between 1 and 100, an integer for a game — that is a job for a random number generator, not for your gut, which always has favorites.

The generator family

Passwords are one branch of a larger family. A numbers generator handles dice rolls and lottery-style draws; a random name generator picks who goes first or who presents on Monday; a spinner wheel does the same with more theater; a free QR code generator turns any text or link into a scannable square, which beats reading a long string aloud. Programmers like to rebuild the password tool in Python as a learning exercise — a few lines of the standard library will do it — but the point of this page is that clicking is faster than coding.

Passwords: the longest your account allows, full character set PINs: digits only, at the maximum permitted length Draws and games: a number range — between 1 and N — sized to the job Sharing: a QR code instead of dictating characters over the phone

A password you can remember is a password worth forgetting — let the manager do the memorizing.
