Passkey Stats Program

Passkeys are supported in all major browsers, as well as native apps. If your audience skews towards older browsers, some of them may not have passkey support yet.

SnapAuth provides a free, opt-in stats program, so you can make a data-informed decision about how to integrate passkeys on your site.

Collect your own

To start collecting anonymous browser support stats for your site, simply add our script to any page you want to measure. This is a great addition on registration and sign-in pages, or you can run it site-wide. It's designed to be lightweight (~0.5KB compressed) and privacy-friendly.

Stats for your site are available through our dashboard.

The script

<script src="https://api.snapauth.app/stats.js"
  data-key="<your publishable key>"
  data-dedupe
  defer></script>

Substitute your publishable key from the dashboard in data-key.

Additional configuration details are documented here.

Privacy

We DO NOT store any of the following (not even in access logs):

  • IP addresses
  • Geographic information
  • Full user-agent strings
  • Any cookies, credentials, etc
  • Referrer data, specific pages/URLs, etc

We also do not set cookies or other trackers. We do set a single bit in sessionStorage to know if stats have already been sent, which you may disable.

This is an opt-in program: we do not collect stats unless you explicitly put this script on your page - even if you're actively using SnapAuth. Using our client SDKs will not transmit this data.

By opting in to stats, you understand that statistics your application contributes can be viewed in the aggregate, not associated to you on our site. You can also see stats specific to your site in the SnapAuth dashboard.

Data sample

In our stats storage system, the data looks like this:

id: 51f0f9d5f1f37e3904101df7eea68c7bc101ac128507139ebffa8cc7d426e004
env_id: env_2893JxW4Wj4cg4hV8fQf4gHr
date: 2024-06-02
platform: Mac OS X
browser: Safari
version: 17.5
category: desktop
data: capabilities data - see below

Capabilities

The browser support data we collect stats on monitors the availability and result of various browser APIs:

{
  "toJSON": true,
  "getClientCapabilities": null,
  "parseRequestOptionsFromJSON": true,
  "parseCreationOptionsFromJSON": true,
  "isConditionalMediationAvailable": true,
  "isPasskeyPlatformAuthenticatorAvailable": null,
  "isUserVerifyingPlatformAuthenticatorAvailable": true
}

We limit to about one data point per day per user per browser. This is done by using a one-way hash of the user-agent string, IP address, a daily-rotating salt, and (if provided) the site id.

How you can use this data

This is an easy way to understand how your users can use passkeys. Decide about going fully passwordless, using passkeys for multi-factor authentication, or other rollout strategies.

How we use this data

We look at this data in aggregate to better understand how reliable browsers are with Web Authentication and passkey APIs. This helps us inform SDK design and optimizations.

It also helps us get an early view about possible browser regressions so we can work with browser vendors on quick fixes.

This does inherently give us basic information about the number of daily unique visitors to your site (on configured pages). We do not look at this and absolutely will never reveal or sell this information.
