3
3. Generate up to 100 passwords in a single request using `count`.
About This Tool
Password Generator creates cryptographically secure passwords using Python's `secrets` module. Configure length, character classes, and batch size. The response includes entropy bits so you can assess password strength.
Why Use This Tool
- Account provisioning — Generate initial passwords for new users
- Secret rotation — Create new API keys, tokens, or database passwords
- Security audits — Generate test passwords with specific entropy requirements
Frequently Asked Questions
How is entropy calculated?
Entropy = log₂(charset_size) × length. For example, a 20-character password from a 91-character set has about 130 bits of entropy.
Are the passwords cryptographically secure?
Yes. Passwords are generated using Python's `secrets` module which uses the operating system's cryptographically secure random number generator.
