Password Generator

Generate a random password with the length and character types you choose: uppercase, lowercase, numbers, and symbols. Uses your browser’s cryptographically secure random number generator, the same standard used for security-sensitive randomness, not a predictable pseudo-random source.

How to use Password Generator

  1. 1

    Open the Password Generator

    Go to tools.slaytic.com and open the Password Generator. No sign-up or account required.

  2. 2

    Choose a length

    Sixteen is a solid default; go longer for accounts that matter most.

  3. 3

    Pick character types

    Toggle uppercase, lowercase, numbers and symbols to match the site’s rules.

  4. 4

    Generate and store it

    Copy the result straight into a password manager rather than writing it down.

How this works in your browser

Randomness comes from the browser’s cryptographically secure generator, which draws entropy from the operating system rather than from a seeded arithmetic sequence. That distinction is the whole point: an ordinary pseudo-random function is predictable to anyone who can infer its seed, which for something like the current time is entirely feasible. Random values are drawn and mapped onto the enabled character sets to build the string. Those sets deliberately omit visually ambiguous characters, capital I and lowercase l, capital O and zero, and the digit one, because in practice the confusion they cause outweighs the negligible entropy they add. Nothing is transmitted, logged or stored anywhere.

Frequently asked questions

Is this password generated securely?

Yes, it uses your browser’s cryptographically secure random number generator (crypto.getRandomValues), not a weaker predictable random function.

Is the password sent anywhere?

No, it is generated and displayed entirely in your browser and never transmitted.

Can I exclude certain character types?

Yes, toggle uppercase, lowercase, numbers, and symbols on or off independently.

Why are some characters missing from the output?

Deliberately. The character sets leave out the pairs people misread and mistype: capital I and lowercase l, capital O and the digit zero, and the digit one. Ambiguity costs you far more in failed logins and retyped passwords than it gains in strength, and adding two characters of length more than compensates.

How long should my password be?

Sixteen characters with mixed types is a sensible default and comfortably beyond brute-force reach. Length contributes more than complexity does, so if you must choose, a longer password with fewer character types beats a short one bristling with symbols.

Should I reuse one strong password everywhere?

No, and this is the mistake that undoes everything else. When any single site is breached, a reused password hands an attacker every other account. Generate a different one per site and let a password manager remember them, which is the only approach that scales past a handful of accounts.

Could the site see the password it generated?

No. It is produced by your browser’s own random number generator and rendered into the page. There is no network request involved at any point, and you can confirm that in your browser’s developer tools.
