Generate a cryptographically secure 32-character password in one click. The 32-character length is the standard for password manager master passwords, encryption keys, and high-security admin credentials. Pick a different length from the chips below if you need 8, 12, 16, 20, or 24 characters.
A 32-character password built from a 94-character pool (lowercase + uppercase + digits + symbols) yields 209.7 bits of entropy — the standard for password manager master passwords, encryption keys, and high-security admin credentials. The math: 9432 = 2.90 × 1063 possible combinations. At 10 billion guesses per second (a fast offline GPU attack), that is roughly 4.38 × 1045 years to brute-force — well beyond the lifetime of the universe at any plausible attack rate.
If you need a 12-character, 16-character, 20-character, or 24-character password for other accounts, the chips above switch the length in one click. For the recommended 32-character baseline for high-security applications, just hit "Generate Password" — the tool defaults to 32 characters on every load.
If you need a different length, the chips above switch in one click. Each length has its own entropy profile:

A 32-character password yields 209.7 bits of entropy and is the standard for password manager master passwords, encryption keys, and high-security admin credentials. To generate a 32-character password, click the '32 chars' preset chip on this page (or any password tool on Toolzie). 32 characters takes roughly 4.38 × 1045 years to crack at 10 billion guesses per second — well beyond the lifetime of the universe at any plausible attack rate.
A 32-character key generator produces cryptographically secure keys of exactly 32 characters. These are ideal for API keys, encryption keys, and other high-security applications where maximum entropy is required. The generator uses the Web Crypto API to ensure true randomness.
This 12-character password generator creates a cryptographically secure password of exactly 12 characters. It uses crypto.getRandomValues (the Web Crypto API) to produce 78.7 bits of entropy from a 94-character pool (a-z, A-Z, 0-9, symbols). A 12-character password is considered 'strong' by modern standards (NIST SP 800-63B) and takes roughly 2 million years to crack at 10 billion guesses per second. Click 'Generate Password' for a new 12-character password, or pick a different length from the chips above.
A 16-character password uses the same 94-character pool as the 12-character default and yields 104.9 bits of entropy — 'extremely strong' by every modern standard. Many security experts recommend 16 characters for high-value accounts like email, banking, and password manager master passwords. To generate a 16-character password, click the '16 chars' preset chip below the length slider (or open /password_generator_by_length/ and pick 16 from the slider). 16-character passwords take roughly 1.18 × 1014 years to crack at 10 billion guesses per second.
A 16-character password is the modern sweet spot for high-value accounts — it produces 104.9 bits of entropy and is rated 'extremely strong' by every standard checker. To generate one, click the '16 chars' preset chip on this page (or any password tool on Toolzie). 16 characters is the default for many enterprise systems and is recommended by NIST SP 800-63B for top-tier security.
A 20-character password uses 131.1 bits of entropy and is 'extremely strong' — overkill for most consumer accounts but appropriate for password manager vaults, encryption keys, and admin credentials. To generate a 20-character password, click the '20 chars' preset chip on this page (or any password tool on Toolzie). 20 characters takes roughly 9.19 × 1021 years to crack at 10 billion guesses per second.
