What is subdomain matching?

Introduction

A subdomain is a separate section of a website identified by a unique prefix added to the main domain name. For example, the support center article you're currently reading is hosted on the subdomain "support." of the domain "nordpass.com."


Parts of a URL diagram breaking https://one.example.com:1000/path into labeled segments: Protocol (https://), Subdomain (one.), Second-Level Domain (example), Top-Level Domain (.com), Port (:1000) and Page path (/path); example and .com are bracketed together as the Domain name

If you wish to learn more, we recommend following our guide on how to set up autofilling via a subdomain.

 

Here’s what happens

The subdomain matching feature simplifies managing autofill suggestions for websites with subdomains in their addresses. Rather than cluttering autofill suggestions with all items, this feature ensures that you only see the password item that matches the subdomain.

Let's say you have multiple password items stored in NordPass that use the same domain — example.com — but different subdomains:

  1. one.example.com
  2. x.one.example.com
  3. one.example.com:1000
  4. example.com

 

Using the subdomain matching feature, you can match any subdomain of example.com with any saved NordPass autofill suggestion:

Table titled Autofill suggestions on websites with Website address and Autofill suggestion columns: one.example.com - Item A; two.example.com - No autofill suggestions; x.one.example.com - Item B; one.example.com:1000 - Item C; x.one.example.com:1000 - No autofill suggestions; example.com - Item D; www.example.com - Item D

This eliminates the need to sift through suggestions to figure out which password to choose. Instead, only one correct option will be suggested.
