About This Tool

This tool generates cryptographically secure random passwords using PowerShell-based logic. It accepts configuration to control length, character classes, and ambiguity handling to produce passwords suitable for accounts, services, and automation scripts.
Conceptually, the generator constructs a pool of allowed characters from uppercase, lowercase, digits, and symbols according to user selections. It uses System.Security.Cryptography.RandomNumberGenerator to select random indices, ensuring high entropy. To meet policy requirements, at least one character from each selected class is included in every password; if length is greater than the number of required classes, the remainder is filled randomly from the combined pool.
Audience and value: IT admins, DevOps engineers, and security professionals benefit from repeatable, scriptable credentials for provisioning, onboarding, and automation tasks. The tool reduces manual password guessing, improves reproducibility across environments, and supports batch generation for bulk provisioning without compromising entropy.
Core features and use cases: length control (8–128), class selection for uppercase, lowercase, digits, and symbols, optional exclusion of ambiguous characters, batch generation, and straightforward integration with PowerShell scripts or CI pipelines. Use cases include creating credentials for Windows servers, cloud services, database accounts, or service principals, with outputs suitable for direct inclusion in scripts or export to files.

How to Use

  1. Provide inputs: length, class options, and optional exclusions
  2. Set batch size if multiple passwords are needed
  3. Run generation to produce password(s)
  4. Capture outputs in variables or write to a file for automation
  5. Use passwords in provisioning scripts or secret stores

Frequently Asked Questions

Find Quick Answers

What length is recommended for most accounts?
For typical user accounts, a length of 12–16 characters with a mix of uppercase, lowercase, digits, and symbols is a solid baseline. For privileged or service accounts, 16–32 characters with diverse classes is advised to maximize entropy and resist attacks.
Can I ensure at least one character from each selected class?
Yes. The generator reserves one character from each chosen class before filling the remaining positions. If the requested length cannot accommodate all required classes, the tool reports a domain error and suggests increasing length or reducing classes.
Can I generate multiple passwords at once?
Yes. You can specify batch_count to produce several independently generated passwords in a single run. Each password conforms to the configured rules and can be exported to a file or assigned to pipeline variables.
Does it exclude ambiguous characters?
Yes. An option to exclude ambiguous characters (similar looking ones like I, l, 1, O, 0) reduces transcription errors. This can be combined with batch generation for user-friendly distribution while maintaining entropy.
Is it compatible with PowerShell Core on Windows, macOS, and Linux?
Yes. The implementation relies on .NET cryptography and runs on PowerShell Core, making it cross-platform. No platform-specific dependencies beyond standard .NET RNG are required.
