If your computer or a portal can’t see your USB token or says “no certificate found”, work through these fixes in order. Most problems are solved by step 3.
A working token shows your certificate in its utility; if not, start with step 1 below.
Try these fixes in order
Check the token light. Plug it in directly (not through a USB hub) and see if the light turns on. Try another port.
Install the right driver. Each brand needs its own driver. Download it from our driver downloads, install it, then restart your computer.
Open the token utility. The driver installs a small utility. If it lists your certificate, the token is working and the issue is the portal or browser.
Run the portal signer. GST needs emSigner and Income Tax needs emBridge running in the background. Start it before you log in.
Run as administrator. On Windows, right-click the signer utility and choose “Run as administrator”.
Remove conflicting drivers. Old ePass or ProxKey drivers can clash with newer tokens. Uninstall drivers for tokens you no longer use.
Check the certificate is valid. An expired DSC won’t show on most portals. Check your expiry date.
On a Mac, allow the driver. After installing, open System Settings → Privacy & Security and allow the driver if macOS blocked it.
Still stuck? We fix it over remote desktop.
Still not working?
Message us on WhatsApp with a screenshot of the error. We connect over remote desktop and fix it, usually in a few minutes.

Frequently asked questions
Why does the portal say “no certificate found”?
Usually the token driver or the portal’s signer utility isn’t installed or running. Install both, restart the browser and try again.
Does my token work on a Mac?
Yes, with the macOS driver for your token brand. Some portal signer utilities work best on Windows.
Will reinstalling the driver delete my DSC?
No. Drivers don’t touch the certificate stored on the token.
