Password Utilities

Generate Pin

Creates random numeric PINs for authentication systems, temporary passwords, or secure codes. Access via MCP in Cursor/Claude Code or GET /v1/password/generate-pin. Returns configurable-length numeric strings like "847291" for 6-digit PINs. Uses cryptographically secure randomization to ensure unpredictable sequences suitable for security applications.

API Endpoint

GET /v1/password/generate-pin

Code Examples

curl "https://tinyfn.io/v1/password/generate-pin" \
  -H "X-API-Key: YOUR_API_KEY"

const response = await fetch('https://tinyfn.io/v1/password/generate-pin', {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);

import requests

response = requests.get('https://tinyfn.io/v1/password/generate-pin',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

How do I generate a PIN using MCP in Cursor or Claude Code?

Call the generate-pin tool through MCP. Most AI agents can specify PIN length parameters, typically ranging from 4-8 digits for common use cases.

What's the default PIN length and can I customize it?

Default length varies by implementation, but you can specify custom lengths. Common options are 4, 6, or 8 digits depending on your security requirements.

Are generated PINs cryptographically secure?

Yes, uses secure random number generation suitable for authentication. Each PIN is unpredictable and independent of previous generations.

Can I generate multiple PINs at once?

Make multiple API calls or tool invocations for separate PINs. Each call generates one unique PIN to maintain security isolation.

What format does the PIN output use?

Returns pure numeric strings like "492837" without formatting, prefixes, or special characters. Easy to integrate into authentication systems or user interfaces.
