Short-lived by default
PINs expire after 5 minutes, 10 minutes, 15 minutes, 30 minutes, 45 minutes, or 1 hour, so they are useful for quick connection flows without becoming permanent identifiers.
FriendlyPIN beta
Give someone a short PIN that expires when you choose.
FriendlyPIN turns IPv4 or IPv6 addresses into temporary connection PINs for quick setup flows, support calls, and pairing screens. Create a PIN, share it, and let it expire automatically.
Every request creates a new PIN and also shows any still-active PINs for the same IP with their remaining time. Each IP can keep up to 5 active PINs at once.

Example use
A support agent can give a temporary PIN.
FriendlyPIN beta works well when the code only needs to last through one setup session. Pick an expiration from 5 minutes to 1 hour.
User: I need to connect this device to my network tool.
Support: Enter ••••. It expires when you choose.

How it works
FriendlyPIN is for temporary connection moments.
Works with IPv4 and IPv6
Use one temporary PIN flow for either address family. The resolver returns the original IP and shows how long the PIN remains active.
Shows other active PINs
Each address can have up to 5 active PINs at a time. When you create a new PIN, FriendlyPIN also lists previous active PINs for that same address so users know what is still valid.
Code lengths
PIN lengths stay separate from IPv4 and IPv6 codes.
4, then 3, 2, 1, then 8+
FriendlyPIN uses 4-character codes first, then shorter codes, and only moves to 8+ if the temporary pool is exhausted.
5 and 7+
IPv6 lookup codes use 5 characters first, then 7+ characters. They never use PIN lengths or the IPv4 length.
Always 6
IPv4 FriendlyIP codes remain exactly 6 characters and can still be calculated locally without any online service.
For developers
Create and resolve temporary PINs online.
POST https://friendlyip.com/api/pin/create/index.php
Send { "ip": "42.13.37.67", "duration_seconds": 900 }
or an IPv6 address. Duration can be 300, 600, 900, 1800, 2700, or
3600 seconds. The API returns the new PIN plus any previous active
PINs for that same IP, up to 5 active PINs at once.
POST https://friendlyip.com/api/pin/resolve/index.php
Send { "pin": "2222" } and the API returns the
original IP and how long the PIN has left. Expired PINs are
rejected.
Dedicated SaaS
Run FriendlyPIN on your own endpoint.
Want FriendlyPIN tuned to your product? PyroSoft can spin up a dedicated FriendlyPIN endpoint under your own URL slug, with a PIN length, expiration window, and PIN pool that match your workflow. The public API stays free for indie use — this is a paid add-on for teams that need their own pool.
Your own namespace
Pick a slug like
friendlyip.com/yourcompany/api. Every PIN endpoint
lives under that prefix so your integration feels branded and
stays separate from the shared pool.
Length you control
Default to 3, 4, 5, 6, or 8+ character PINs to balance human-friendliness against how many can be active at once. We pick the allocator that fits your chosen default.
Expiration that fits your flow
Pick how long PINs stay valid, from 5 minutes up to 7 days. Quick support codes, all-day pairing sessions, or anything in between.
Your own PIN pool
Your PINs live in a dedicated pool so your traffic never competes with the public FriendlyPIN pool, and short PINs stay available for your users.
Contact to set up
Dedicated endpoints are a paid add-on from PyroSoft Productions. Reach out with your preferred slug, default PIN length, and expiration window, and we will get your namespace live.
