Websites That Use Linkedin Sign-in in 2026

We track 67,052 websites that use Linkedin Sign-in in 2026. Those sites span 45 industries and 27 countries. The crawler re-checks each domain daily. So the count moves as sites adopt Linkedin Sign-in or drop it.

Linkedin Sign-in belongs to the Authentication category. Sites in that category tend to share a similar stack. As a result, they often share buying patterns too.

The table above shows a sample of 100 matched companies. Each row carries an industry, a country, and a live domain. You can search it, sort it, and export it.

Adoption is not spread evenly. Instead, a few industries account for most of the matched sample:

• Information Services14.000000000000002%
• Information Technology and Services9%
• Hospitals and Health Care7.000000000000001%
• Construction5%
• Human Resources5%

Information Services leads that list. However, the long tail matters just as much. Adoption reaches 45 industries in total. So you can narrow the list to the segment you sell into.

The matched companies sit in 27 countries. These lead the sample:

• 🇺🇸 United States 46
• 🇬🇧 United Kingdom 11
• 🇳🇱 Netherlands 7
• 🇫🇷 France 4
• 🇧🇷 Brazil 3

United States is the largest single market in this sample. Because the country is stored per row, you can filter before you export. That keeps your outreach inside one timezone and one legal regime.

Start with the table above. Then follow these four steps to turn it into an outreach list:

1. Filter the sample. Narrow by industry or country until the rows match your ideal customer profile.
2. Export the domains. Share the page to unlock the CSV, or sign in for the full dataset.
3. Find the people. Run each domain through Domain Search to pull every work email behind it.
4. Verify before you send. Pass the results through the Email Verifier so your bounce rate stays low.

Working at volume? Push the whole export through Bulk Tasks instead, or call the Domain Search API directly from your own stack.
