16 random characters from a pool of 88, with every selected type guaranteed. Crack time assumes 10 billion guesses per second.

Your passwords

Choose your options and press Generate

  • Truly random

    Uses your browser's cryptographic random number generator, with every allowed character equally likely.

  • Honest strength

    Shows the real entropy of your settings in bits and how long a brute-force attack would take.

  • Up to 50 at once

    Generate a batch for new accounts, test users or a team, and copy them all in one tap.

Free strong password generator

A strong password is long and random. People are bad at being random — we reach for names, dates and @-for-aswaps that attackers already try. This generator picks every character with your browser's cryptographically secure random number generator, so there's no pattern to guess.

How it works

  • Secure randomness: characters come from crypto.getRandomValues, with rejection sampling so no character is more likely than another.
  • Every type included: each password contains at least one of every character type you select.
  • Readable options: skip look-alike characters (like l, 1 and I) for passwords you'll type by hand, or symbols that break code and spreadsheets.

Strength levels

  • Weak (under 40 bits): cracked in under two minutes.
  • Medium (40–60 bits): minutes to a few years.
  • Strong (60–80 bits): years to millions of years.
  • Very strong (80+ bits): far beyond any brute-force attack today. 16 random characters from all four types is about 103 bits.

Entropy is length × log₂(pool size), less a tiny correction for guaranteeing every type. Crack times assume 10 billion guesses per second — an attacker with GPUs and a leaked database of fast hashes.

Best practices

  • Use at least 12 characters — 16 or more for email and banking.
  • Use a different password for every account.
  • Store them in a password manager instead of a notebook or WhatsApp chat.
  • Turn on two-factor authentication wherever it's offered.

Passwords are generated in your browser and never sent anywhere or saved. Close the tab and they're gone.

Private by design. Everything runs in your browser — nothing you enter is uploaded or stored by AISeekho.
