Lookalike link checker

Paste a link from an email or a text message. This page checks whether its address imitates a site people sign in to, such as a bank, a delivery service or a tax office.

Nothing you paste leaves this page. The check runs in your browser.

How to check this yourself

Open your browser's developer tools (F12, or Cmd+Option+I on a Mac) and choose the Network tab. Paste a link and press Check link. No new request appears, because the page already has everything it needs. The only request this page makes on its own is a page-view count when it first loads, and that carries the page's address, never anything you type.

This checker needs JavaScript turned on. It still runs entirely in your browser.

Try an example:

What this page checks

  • Characters that look like letters: g1thub.com, rnicrosoft.com.
  • Letters from other alphabets, such as a Cyrillic а in place of a Latin a.
  • A brand's name with extra words: paypal-secure-login.com.
  • A real address in front of another site: paypal.com.secure-login.tk opens secure-login.tk.
  • Small spelling slips in longer names: amazn.com.
  • A name written before the real address, and addresses that are only numbers.

What it doesn't check

  • What the page contains. A real site can be hacked, and a copy of a site that isn't on the list won't be recognized.
  • Where a shortened link leads. The page makes no network requests, so it can't open one.
  • Spelling slips in short names and ordinary words, such as UPS or Orange, because too many real sites differ from them by one letter.
  • Links that don't resemble the site they copy. Many phishing links use an unrelated name, so a clean result is not a safe result.
  • Whether a site is on a list of reported phishing sites.

What it compares against

About 140 companies and services that are popular in the United States, France and Japan, and that phishing often copies: banks and card companies, payment apps, delivery services, tax and benefit offices, phone companies, and the large sites most people sign in to.

When an address belongs to one of them, the page says so. That tells you who owns the address. It doesn't tell you the page behind it is safe.

Why it never asks for your passwords

The best comparison is with the sites you actually have logins for, because a phishing link only works on a site where you have an account. A web page can't see your logins, and no page should ask you to type them in to check them.

So this page uses a fixed list instead. It can recognize copies of the sites on that list, and nothing else.

Check links against your own logins

In the Walilock app, the phishing scanner compares a link against the sites you actually have logins for, on your device. It comes with Personal+ and Family, which you can try free for 14 days.
