VELNARO

Password Generator

Generate secure passwords using your browser’s cryptographic random number generator. Choose the length and character sets, see the estimated strength, and copy the result. Nothing is transmitted or stored.

Estimated entropy

103 bits

Strength

Excellent

Resistant to offline attacks

Character pool

86 characters

Passwords

:_;y^?_^q[Rq5{E.

Passwords are generated locally with crypto.getRandomValues and are never sent to VELNARO or stored. Save them in a password manager.

Formula

Entropy (bits) = password length × log₂(size of the character pool)

How it works

  1. 1The generator uses your browser’s cryptographic random number generator, not Math.random, so the output is not predictable.
  2. 2Entropy measures how hard the password is to guess: each character adds log₂(pool size) bits.
  3. 3Length matters more than complexity. A 16-character password from a 90-character pool has about 104 bits of entropy.

Example

Input

16 characters, all character types

Result

≈ 104 bits of entropy — excellent

Frequently asked questions

Yes. They are produced with crypto.getRandomValues, the same cryptographic source browsers use for security-sensitive operations.
