Access marker

Choose the URL marker that shows the widget on a site without login, and replace the link when it changes.

Prerequisites

  • Authentication set to Site without login (wizard: Public site, no login).
  • Site URL saved under Settings → Connection, so the client link can be built.

App with login hides Access marker. The widget is shown from data-token instead. See Auth methods.

Steps

Open Settings → Client access.

  1. The field Access marker starts as modifee. The line under it is "The widget stays hidden until the client opens /?modifee", with your marker and an example URL.
  2. Type another marker, or press Generate random. Generate random fills 24 letters and digits.
  3. Press Copy to copy the full client link. The button then says "Copied".
  4. Press Save.

A marker is 3 to 64 letters, numbers, underscores, or hyphens. The client link is the site URL plus ? and the marker, for example https://their-site.com/?modifee.

Send that link. The widget checks the query against the saved marker, removes the marker from the address bar, and keeps the button visible while they browse that tab. Ctrl+Shift+M on the site shows the widget too. Use that while you are setting it up.

The marker only decides whether the button is visible. Anyone who has the link, or who uses Ctrl+Shift+M, can open the widget. Who can send a request is Who can request changes?. See Allowed emails.

Change the marker

  1. Edit Access marker or press Generate random.
  2. Press Save.
  3. Confirm "The old link will stop working. Send the new link to your client."

The previous ?marker no longer unlocks a new visit. Send the new link. A tab that already showed the widget keeps it until that browsing session ends.

Verify

  1. Open the site with no marker. The button stays hidden.
  2. Open the copied link. The button appears, and the marker disappears from the URL.
  3. Browse to another page in the same tab. The button stays.
  4. After a change, the old link leaves the button hidden. The new link shows it.

Troubleshooting

  • "Use 3 to 64 letters, numbers, underscores, or hyphens."
  • "That name is reserved. Choose another marker." Reserved names are page, id, q, s, ref, fbclid, gclid, and anything that starts with utm_.
  • Copy stays disabled until Site URL can build a link. Save the URL under Settings → Connection.
  • The button stays hidden on the plain site URL. That is the marker. Open the client link, or press Ctrl+Shift+M.
  • The widget is visible and the email is rejected. The marker did its job. Add the address under Allowed emails. The message is MDF-AUTH-002.
  • Widget not showing.
