Lowercase letters (a–z)

Numbers (0–9)

Symbols (!@#$ etc.)

Exclude look-alike characters (O, o, 0, 1, l, I, |)

Your password

UUID v4

How the generator works

Cryptographically secure — passwords come from your browser's native crypto.getRandomValues engine; UUIDs from crypto.randomUUID (a built-in v4 fallback is included).
Entropy in bits — calculated as length × log₂(pool size); the badge turns from amber to blue as strength rises.
Nothing leaves your device — generation happens locally, nothing is stored, logged or transmitted, and a refresh produces brand-new values.
Excluding look-alikes — removes O, o, 0, 1, l, I and | from the pool to avoid transcription mistakes.
