Install the seal on your site

One line to paste, wherever your site lives. No secret key: your domain is read from the visitor's address bar — precisely what a fake site cannot imitate.

<script src="https://seal.lifaio.com/sceau-vivant.js?org=ORG-XXXXXX" async></script>
<noscript><a href="https://seal.lifaio.com/s/ORG-XXXXXX" target="_blank" rel="noopener"><img src="https://seal.lifaio.com/seal/ORG-XXXXXX.svg" alt="Seal LIFAIO" width="264" height="58" style="border:0;"></a></noscript>

WordPress — easiest, nothing of ours to install

Plugins → Add New, search for “WPCode” (or “Header Footer Code Scripts”), install and activate. These are widely used plugins made for exactly this.
Code Snippets → Header & Footer → “Footer” box, paste the line, save.
Done. The line survives your theme updates — which is the whole point of doing it here rather than in the theme file.

WordPress — straight into the theme (not advised)

Appearance → Theme File Editor → footer.php, paste the line just before </body>.
⚠️ The next theme update will WIPE this change and the seal will vanish without warning. Only do this on a child theme.

Shopify

Online Store → Themes → … → Edit code.
Open layout/theme.liquid and paste the line just before </body>.
Save. The seal shows on every page, cart and checkout included.

Wix

Settings → Custom Code → Add Custom Code.
Paste the line, choose “All pages” and placement “Body — end”.
Apply.

Squarespace

Settings → Advanced → Code Injection.
Paste the line into the “Footer” field.
Save.

Webflow

Project Settings → Custom Code.
Paste the line into “Footer Code” (before </body>).
Publish the site.

Hand-built site, or any other tool

Paste the line just before the </body> tag of your shared template.
If your site has no shared template, paste it on each page — or use the static image, which works everywhere.

🎨 The seal is alive — and that is what exposes a copy

Below the badge, a band changes every minute: the 6-digit code, a colour dot, the WRITTEN NAME of that colour, and a second word. A forger can save your badge and serve it from their own site — but their image will stay frozen forever.

Reload the page: the band changes. A copy never changes.
Select the words with your mouse: on the real seal they highlight; on a copied image nothing happens.
Compare the words with those Seal shows for that domain at the same moment.

🔒 Does your site block third-party scripts (strict security policy)? Use the seal IMAGE from your portal instead: it works everywhere, including in an email signature.
