Selenium Chrome suppress/dismiss client certificate selection dialog

Question

How can I suppress or automatically dismiss the client certificate selection dialog with selenium (chrome driver)?

I can't use this certificate, because it is stored on a chip card and I would have to enter a PIN. If no card is available, our website used a credential based login and I want to test this.

Answer 1

I found a solution to this problem: You must use chrome parameter - AutoSelectCertificateForUrls

Add this to the windows registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\AutoSelectCertificateForUrls\1 = "{"pattern":"https://yoursite.com","filter":{}}"

Answer 2

In linux you need this file set:

$HOME/etc/opt/chrome/policies/managed/auto_select_certificate.json

With this content:

{
  "AutoSelectCertificateForUrls": [ "{\"pattern\":\"*\",\"filter\":{}}" ]
}

With this set it should allow every installed client certificate automatically.
