Hey bunqers 🌈,

We recommend updating your browsers and your device’s operating system to the latest version.  

On October 17, 2026, 8 security certificates used globally were found to be unsafe. There is no impact on bunq accounts: your money is completely safe and your bunq app is secure.

What happened?

Websites use security certificates to prove they’re real. When you see the padlock next to a web address, your browser has checked that certificate. 

On October 17, 2026, 8 certificates from a certificate provider used by websites worldwide were compromised. Someone with these certificates could make a fake website look exactly like the real one: with the correct web address and the padlock, and your browser wouldn’t warn you. This could affect anyone browsing the web, on any website, including bunq.com. 

How does this affect my bunq account? 

Your bunq account is safe and the bunq app on your iOS or Android mobile devices is not affected. It has an extra layer of protection called certificate pinning, which means it only connects to bunq’s own certificate — so a fake certificate won’t work on it. 

The issue affects any website you open in a browser. This could include bunq websites, like bunq.com, web.bunq.com, and bunq.me. A fake bunq site could show the real bunq address and a padlock if: 

• Your browser or operating system hasn’t been updated since October 19, 2026

• Someone has intercepted your connection, for example on public Wi-Fi

Updating your devices removes this risk.

How do I update my browser and device?

It takes a few minutes. Update every browser you use, then restart it.

1. Chrome: open Settings → About Chrome

2. Firefox: open the menu → Help → About Firefox

3. Edge: open Settings → About Microsoft Edge

4. Safari and macOS: open System Settings → General → Software Update

5. Windows: open Settings → Windows Update

6. iPhone or Android: open Settings → Software Update (on Android, it’s under System)

What’s bunq doing to keep me safe?

We always keep your account safe. Here's how:

• We regularly update our servers and our employees’ devices.

• The bunq app is protected by certificate pinning, so it stays safe, even on an outdated device. 

How do I stay safe until I’ve updated my browsers and devices?

Here are a couple of things to keep in mind to stay safe: 

• Avoid logging in to bunq web on public or unknown Wi-Fi networks

• Watch out for phishing like fake emails, text messages, or ads that link to a site that looks like bunq

• Open bunq through your secure bunq app or type in the bunq.web address yourself when browsing online

• Remember that bunq never calls you. If we need to contact you, we’ll always do this through your encrypted Support chat in the bunq app 

• If something feels off, report it to us

What can I do next?

There’s nothing else you need to do once your devices are updated. We’ll update this page if anything changes.
