Companies Using Sign in with Apple

I expected Sign in with Apple to look like a smaller copy of Google's button. In our October 2026 crawl it looks more specific than that: a second login option on account pages. A domain counts here when the page we load carries Apple's sign-in script (appleid.auth.js), its AppleID object, a link to Apple's authorisation page, the appleid-signin-client-id meta tag, or a button that reads "Sign in with Apple", "Sign up with Apple", "Log in with Apple" or "Continue with Apple". I checked 60 random live domains in a browser, and 43 of the 49 pages that loaded past a bot wall showed one of those markers. That gives 10,499 live domains, 4,464 of them matched to a company, 8th of 54 in Identity & Access (SSO/CIAM).

Where the button sits

Many detections aren't home pages. Uber's is drivers.uber.com, Indeed's is profile.indeed.com, Revolut's is app.revolut.com, and TED and Real Madrid use auth.ted.com and signin.realmadrid.com. That changes how you count, because a platform that hands out subdomains shows up once per subdomain. 692 of the 10,438 cleaned domains are store subdomains of sahibinden.com, the Turkish classifieds site, and 144 are podcast pages on podbean.com. On both, the button comes with the platform's own login page, not from the store owner or the podcaster.

Sales signal: roll the list up to root domains before you count accounts. Those 836 rows collapse into two platforms.

Growth since June

The chart reads 5,826 domains in June 2026, 7,114 in July, 8,559 in August, 10,115 in September and 10,499 in October. That's an 80.2% rise in four months, and I wouldn't read it as adoption. The domains we crawl turn over every month, with dead sites dropping out and new ones added, and our detection keeps reaching more hostnames. August shows it: 660 of the sahibinden.com subdomains were first detected that month. Of the 10,746 domains live in our records, 4,226 were first seen in August or later.

Exits are small. 2,080 domains dropped it since we began tracking it on 16 March 2026. When I checked, 142 of them still showed it on another hostname, and about half of the rest had been seen with it only once, so I wouldn't call that number churn.

"Sites add Apple's button next to Google's, and they keep both. Four in five of the domains we've ever seen with the two buttons still run both." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: the pool is about 10,500 domains and grew by only 384 between September and October. Size the market on today's count, not on the June-to-October slope.

Who offers it

48.75% of matched companies with a known size have 1 to 10 employees and 27.05% have 11 to 50. That's small, but less so than Google Sign-in, whose profile puts 64.47% in the smallest band. Age points the same way: 41.59% were founded in the 2010s and 31.55% in the 2020s, so 73.14% date from 2010 or later. There are 172 companies above 1,000 staff, and the named ones use it where customers log in. Uber has it for drivers, Indeed for job seekers, Amazon on its jobs site, Panasonic on its European customer portal and Wix on its account login. Older brands appear too: Shiseido (founded 1872), Real Madrid (1902) and Mahindra & Mahindra (1945).

Sales signal: at a large company, the owner of this button is whoever runs the login for one product. Find that team before you call the corporate web team.

Where the sites are, and what they do

The United States has 1,431 matched companies, the United Kingdom 282, India 228, Canada 167 and Germany 138. Poland is sixth with 117, ahead of France (114) and Spain (102). The US, UK, Canada and Australia (95) hold 1,975 of the 4,464 matched companies, 44.2%. South Korea shows only 62, but Naver Analytics, a Korean tool, runs on 3.24% of all Sign in with Apple domains, so I suspect Korean sites are under-matched to company records rather than rare.

By industry, Technology, Information and Internet leads at 10.72%, then Software Development (8.68%) and Restaurants (5.54%). With IT Services and IT Consulting (3.91%), software and internet businesses make up 23.31%. Restaurants and Food and Beverage Services (2.06%) add up to 7.60%, and the restaurant sites are often ordering pages, like Caribou Coffee's and Hungry Jack's, where a returning customer would rather not fill in a form. Financial Services is 4.72%, with Revolut, Qonto and Bitget on the list.

Sales signal: restaurant ordering and fintech logins are the two verticals where the button points to a consumer account base. Those are the lists to hand to loyalty, fraud and identity vendors.

Apple next to Google

Google Sign-in runs on 65.3% of Apple's domains, and 7,105 domains offer both buttons today. Of the 8,911 domains we've ever seen with both, 79.7% still run both, so the pair fails our switching tests: sites add buttons rather than trade them. LinkedIn Sign-in overlaps far less, with 49 domains running both today out of 150 ever seen with both. Google's button is on 213,670 domains, about 20 times Apple's 10,499, counted after its own page removed for-sale and gambling landers.

"I read Apple's button as the one a team adds second. When it's there, someone decided returning customers were worth a faster login." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: a site with both buttons already manages several login providers and may want them in one place. Auth0, whose Apple connection adds Sign in with Apple to an app or website, is on 6,095 domains in this category, yet only 9 run it beside a detectable Apple button today.

The stack around it

Google Analytics runs on 68.18% of live Sign in with Apple domains. Next.js is on 16.96% and WordPress on only 11.82%, Firebase on 9.94%, Vercel on 5.82%, and CleverTap, a mobile engagement platform, on 5.39%. That reads as product teams shipping web apps. Shops are rare: WooCommerce is on 1.83% and Shopify on 1.53%. Adobe Experience Manager, on 5.37%, marks the enterprise end, and Amazon Web Services hosts 19.86%.

Sales signal: pitch developer tools, mobile analytics and customer identity here, not themes or store plugins. A Next.js and Firebase team that already wired up Apple's sign-in is a technical buyer.

What Apple asks of developers

Apple set App Store rules for Sign in with Apple on 12 September 2019: new apps had to follow them straight away, and existing apps and updates by April 2020 (Apple developer news). In January 2024 it rewrote guideline 4.8 so it no longer names its own button, as 9to5Mac reported. The current App Store Review Guidelines say apps that use a third-party or social login, Google Sign-In among them, must also offer an equivalent login that limits data to name and email, lets users keep their email private and doesn't collect interactions for advertising without consent. Websites aren't bound by it. Apple lists Sign in with Apple among the capabilities included in the Apple Developer Program, which costs 99 USD per membership year (checked 12 October 2026).

Sales signal: the web count misses the iPhone side, where guideline 4.8 applies. Check a prospect's App Store listing before you pitch anything app-side.
