Strength
Very strong · about 152 bits
As random as a 128-bit key. Fine for API keys and encryption secrets.
The estimate assumes an attacker knows which settings you picked.

How this works
Every secret comes from crypto.getRandomValues, the browser's cryptographically secure random number generator. The page doesn't store what it generates or send it anywhere.
Passphrases use the EFF Large Wordlist (7,776 words, CC BY 3.0).
Private: runs in your browser
This tool runs entirely on your device. What you enter isn't sent to this site or to any other service, and nothing is kept after you leave the page.
Copying puts the secret on your clipboard, and some clipboard managers keep a history. Paste it where it belongs, then copy something else.
