Enable Prompt for Certificate in Internet Explorer


By default, Internet Explorer does not prompt to send a certificate if only one certificate is present. If a valid certificate matches site requirements, it is automatically sent.
This is useful for basic users, for who authentication is transparent, but some users might need an alternative authentication.


  • Run Internet Explorer
  • Menu Tools -> Internet Options
  • Select Tab Security
  • Select Local Intranet (if connected at CERN on the CERN domain, otherwise select Internet)
  • Click Custom Level
  • Find the Miscellaneous part
  • Check Disable for Don't prompt for client certificate selection when no certificates or only one certificate exists.
  • Click Ok -> Ok

Now when entering a Website asking for a certificate, you will be prompted for a certificate selection. Click cancel and you will enter the website anonymously.
