When to use this tool
- Create a unique credential for a new account.
- Generate test passwords with a specific character policy.
Limits to know before using it
Entropy estimates describe the generator settings, not the safety of how you store or reuse a password. Keep credentials in a trusted password manager.

Frequently Asked Questions
No. Password generation uses browser crypto locally and does not send generated values anywhere.
Entropy estimates the search space from length and selected character sets. Higher bits mean a larger space to brute-force.
Ambiguous characters such as O, 0, l, and 1 can be hard to read or transcribe. Excluding them improves manual entry at the cost of a smaller character pool.
