What is PassGeni?
PassGeni is a password generation tool that exposes a simple REST API for generating secure passwords from any app, framework, or no-code workflow. It is designed to be quick to adopt: one POST endpoint, plain JSON input, and JSON output that includes generated passwords plus entropy and audit details. The service also positions itself as suitable for compliance-driven environments, with presets for standards like HIPAA, PCI, SOC 2, ISO, NIST, and DoD on the Team plan. It supports both standard passwords and memorable passphrases, and it includes a post-quantum mode with a larger entropy target and expanded symbol set.
The product is aimed at developers, teams, and automation builders who need password generation inside software rather than in a standalone browser tool. It highlights compatibility with languages and platforms such as Node.js, Python, PHP, cURL, Zapier, n8n, GitHub Actions, AWS Lambda, Vercel Edge, Cloudflare Workers, and common backend frameworks. The API is intentionally minimal, with an empty request returning a default 18-character password, and the docs emphasize that no SDK or install is required. The service also includes a live tester and ready-to-run examples for quickly validating integrations.
A key part of the product is flexibility in generation rules. Users can set password length, count, profession seed, mode, compliance profile, and quantum mode through request parameters. The docs indicate that all parameters are optional and that free-tier requests do not require an API key. The API response is structured for programmatic use, returning a passwords array, entropy value, tier label, and audit object.
PassGeni also distinguishes between server-side generation through the API and client-side generation through its web generator. The documentation explicitly notes that API generation transits their server over HTTPS, while the web generator is the path for zero-knowledge client-side generation. That makes the tool relevant both for straightforward app integration and for teams that care about security architecture, compliance evidence, and operational simplicity. The website repeatedly frames it as a universal password generation building block rather than a consumer-only password utility.
PassGeni pricing
Pricing model: Free
The website describes a free tier and a Team plan. Free tier access requires no account and no API key, and it includes 50 calls per day per IP; the smallest request returns one 18-character password with sensible defaults. Team features require an API key passed in the request body, and the docs say Team enables higher limits and compliance profiles such as HIPAA, PCI, SOC 2, ISO, NIST, and DoD. The website does not show a full price list in the available content, but it clearly separates free usage from paid Team access and notes that Team keys can be managed from a dashboard.

Frequently asked questions about PassGeni
What does PassGeni generate?
PassGeni generates secure passwords through a REST API, and it can also generate memorable passphrases when you set the mode to passphrase. The response includes a passwords array, entropy information, and an audit object so the output is easy to consume in code and easier to review for compliance-related use cases.
Do I need an account or API key to try it?
No. The free tier does not require an account, signup, or API key to test the API. The documentation says you can send a POST request directly to the endpoint and get a password back, with free-tier usage limited to 50 calls per day per IP.
What parameters can I control?
You can set apiKey, profession, length, count, compliance, mode, and quantum in the request body. The profession seed can be things like developer, doctor, finance, designer, legal, or educator, length ranges from 8 to 32, count controls how many passwords are returned, and compliance and quantum unlock higher-end Team features and stricter generation behavior.
What does the API return?
A successful response returns HTTP 200 with a JSON object that includes passwords, entropy, tier, and audit. The passwords field is an array of generated strings, entropy reports the entropy in the first password, tier shows whether the request used free or team limits, and audit provides details about the character pool and entropy source.
Which integrations does PassGeni support?
The product is built to work anywhere an HTTP request can be made. The documentation specifically mentions Node.js, Python, PHP, cURL, Zapier, n8n, GitHub Actions, AWS Lambda, Vercel Edge, Cloudflare Workers, Postman, Insomnia, Laravel, Django, Rails, Spring Boot, Go stdlib, and Rust reqwest.
What are the free-tier limits?
Free usage is limited to 50 requests per day per IP. The docs also say that an empty request body returns one 18-character password, and the free tier caps count at 10 passwords per request. Compliance presets are not part of the free tier.
What is Team plan for?
Team is for users who need the API key flow, higher request limits, and compliance-specific generation modes. The documentation says Team supports compliance profiles like HIPAA, PCI, SOC 2, ISO, NIST, and DoD, and it allows much larger count values than the free tier.
Is the password generation client-side or server-side?
The API is server-side, which means the password transits PassGeni’s server over HTTPS when you use the REST endpoint. The docs explicitly note that if you need zero-knowledge client-side generation, you should use the web generator instead of the API.
What is quantum mode?
Quantum mode is an advanced generation option that uses 512-bit entropy, an expanded symbol set, and a 20-character minimum. It is presented as a stronger mode for users who want a higher-security configuration than the default password generation settings.
How quickly can I get started?
The documentation says you can go from zero to working code in about 30 seconds. The flow is to choose a language, send one POST request to the generate endpoint with JSON, and then use the returned passwords array in your application.
