Secure Password Generator

The tool generates cryptographically secure passwords by combining user-selected character sets with a user-defined length. It does not store or transmit the generated values and operates entirely client-side, reducing exposure since credentials never leave the device. It supports typical corporate and personal use cases including onboarding new users, resetting passwords, and provisioning access to services and systems.
Conceptually it relies on a cryptographically secure RNG to sample from the active alphabet and assemble a password of the requested length. The theoretical password entropy is calculated as log2(C^L) where C is the number of allowed characters and L is the password length; if repeats are disallowed, the tool adapts toward permutation-based limits and clearly indicates any policy implications.
Ideal users include individuals creating accounts, security teams provisioning access for teams, developers integrating in CI/CD workflows, help desks supporting password resets, and IT admins enforcing password policy across applications. Use cases span single-user access, shared service credentials, and temporary access keys.
Core features include length control, charset toggles for uppercase, lowercase, digits, and symbols, optional exclusion of ambiguous characters (such as I, l, 1, O, 0), a passphrase mode for longer, word-based generation, a mode to prohibit or allow character repeats, and an entropy/strength indicator to aid policy decisions and audits.
