About Linkedin Sign-in

A social login button is a small piece of markup that says something quite precise about the audience a site expects. Offering Linkedin Sign-in instead of a consumer identity provider means the people signing up are assumed to have a professional profile worth reusing, with a job title, an employer and a work address attached. As of September 2026 we detect the integration on 26,649 sites, and the character of those sites is uniform enough to work as a filter by itself. Job boards, recruiting tools, business software, event registration and lead capture built for a professional audience all recur.

Detection depends on what the integration leaves in the page. The JavaScript widget, the button markup and outbound references to the provider's authorization endpoint are all visible to a crawler, and a match on any of them is solid evidence. An implementation that runs server-side, with a plain styled link and a redirect handled after the click, leaves far less behind. Our count therefore leans toward sites using the drop-in widget and away from custom builds, which is worth knowing before anyone treats the figure as the size of the market.

The country breakdown is the part of this record most likely to be misread. Denmark accounts for 8,674 of the sites, which is not where anyone would guess demand for professional identity sits. A single platform vendor, a site builder or a recruitment software company that deploys the same login template across its whole customer base will move a country share on its own. Country here means where a domain is attributed, not where its users work, and the geographic split is a fact about site operators rather than about professionals.

Microsoft operates the service, which has been available since 2011 under a Proprietary model, and hosted operation is why no version appears in our record. An identity provider rolls its changes forward on its own servers and the site owner never pins a release, so there is no version string to collect and no way to separate a recent integration from one wired up years ago. The absence of version data is a property of hosted identity rather than a gap in the crawl.

What the list answers is a question about populations. One domain checked by hand tells you that a company offers professional login. The whole set shows which categories of product treat a work profile as the primary identity, which other authentication options sit beside it on the same pages, how often it appears with no consumer alternative offered at all, and which vendors have standardised on it across everything they host. Competing identity providers use files like this to size a switching market, business sellers use them as a ready-made filter for buyer-shaped sites, and privacy researchers use them to trace where authentication traffic actually goes.
