Password Generator

Create secure random passwords using the browser's crypto API. Choose length (4-64), include uppercase, lowercase, numbers and symbols, exclude ambiguous characters, and see a live entropy-based strength meter. Regenerate or copy instantly.

Examples

Input · Each generation produces a new random value.
Length 16, all sets on
Output
A new random 16-character password

How it works

Each character is picked independently from the sets you switch on, using the browser’s cryptographic random source. With all four sets on, the pool has 87 characters: 26 upper case, 26 lower case, 10 digits and 25 symbols.

Entropy is length × log2(pool size). The meter calls a password Weak below 40 bits, Fair below 60, Strong below 80 and Very strong from 80 up. Because every character is drawn at random, a short password can happen to contain no digit or no symbol; if a site demands one of each, press Regenerate. “Exclude ambiguous characters” removes look-alikes such as O and 0, or l and 1, along with quotes and brackets.
