How Duolingo phishing works
Phishing against Duolingo follows patterns common to business software & payroll. Typical lures:
- A payroll or HR notice asking employees to "re-verify direct deposit details".
- A shared-file or invoice link that leads to a fake single sign-on page.
- A licence-expiry or security-patch email aimed at administrators.
- An e-signature or expense-report request from a spoofed manager.
Red flags
- Direct-deposit or bank-detail changes requested by email are a classic payroll-diversion trick.
- The sign-in page is not your company's single sign-on or the vendor's official domain.
- The request comes from a manager or vendor outside normal channels.
Real Duolingo domains
If the address in your browser is not one of these (or a subdomain of them), it is not Duolingo. The list is not exhaustive.

Tell your IT/security team straight away, reset the password and revoke active sessions, check for forwarding rules and changed payroll details, and enable phishing-resistant MFA for administrators.
Protecting a brand like Duolingo from lookalike domains
If you run security, brand or fraud for a company that is copied this way, this is the order that works in practice:
- Enforce DMARC. Move your policy to quarantine, then reject, so attackers cannot send mail that passes as your domain.
- Watch new registrations. Lookalikes appear daily; the earlier you see one, the sooner you can act, ideally before the first email goes out.
- Register the obvious typos and keyword variants you can afford to hold, and check which lookalikes are already registered by someone else.
- Report fast. A live fake needs a request to the registrar and host, plus a report to browser safe-browsing lists and the public feeds shown above.
- Tell your customers where you will and will not ask for logins, codes or payments.
Protect your brand from lookalike domains
Duolingo is one of 2108 brands in this index, but attackers copy any company whose customers log in or pay. PhishPin checks your domain for registered lookalikes, email-spoofing gaps and listings in these same phishing feeds, then helps you get the fakes taken down.

Questions about Duolingo phishing
How can I tell if a message from Duolingo is phishing?
Check the sender and link domain first. Direct-deposit or bank-detail changes requested by email are a classic payroll-diversion trick. The sign-in page is not your company's single sign-on or the vendor's official domain. The request comes from a manager or vendor outside normal channels. When in doubt, do not use the link: type duolingo.com into your browser or open the official app.
How many Duolingo phishing sites has PhishPin found?
As of 7 Nov 2026, 13 hostnames referencing Duolingo appear in the phishing feeds PhishPin indexes (17 reported URLs). These are reported hostnames, not a count of sites that are online today; many are removed quickly and some matches are coincidental.
What do fake Duolingo domains look like?
In our data, the most common ending for reported hosts is .host. The brand is most often combined with the word "support". 12 hosts put the brand name in a subdomain of an unrelated site. Always read the part of the address just before the first single slash: that is the real site. Real Duolingo addresses end in duolingo.com.
What should I do if I entered my details on a fake Duolingo page?
Tell your IT/security team straight away, reset the password and revoke active sessions, check for forwarding rules and changed payroll details, and enable phishing-resistant MFA for administrators.
How do I report a fake Duolingo website or message?
Forward phishing emails to reportphishing@apwg.org, report scams at reportfraud.ftc.gov, and report the page to Google Safe Browsing. Also tell Duolingo through the contact options on its official website (duolingo.com).
Is it safe to visit the domains listed on this page?
No. They are shown defanged, with dots in brackets, so they cannot be clicked by accident. Do not type them into a browser. Listings are warnings from automated matching, and some are harmless coincidences. Treat everything listed as potentially phishing, infected or malware, and have a certified security expert review any list before you block, import or act on it. PhishPin is not responsible for loss or damage from using this data.
How does PhishPin find lookalike domains of Duolingo?
We read the daily list of newly registered domains (1,050,000 domains over the last 15 days) and flag those that contain the brand name, differ by one character or swap look-alike characters. A match is a warning sign, not proof of abuse.
How can a company protect its own brand from lookalike domains like these?
Publish an enforced DMARC policy so nobody can send mail as your domain, monitor newly registered domains that resemble your name, register the obvious typo domains, and file takedown requests with the registrar, host and browser safe-browsing lists when a fake goes live. PhishPin's free brand audit checks the first three for your domain.
