Information you will need

To complete these instructions you'll need some information specific to your home site/organisation, plus your own credentials, as listed below. If any of the details in your wifi profile are incorrect then your authentication will fail and you will not gain wifi access via eduroam. The IT department of your home site will be able to provide you with these details:

Information requiredSample string in the instructions below
Your home site's domain name as would appear in, for example, your e-mail address e.g.
[OPTIONAL] The name of the CA certificate used by your home site for eduroam. You will not require this if your site is using a public CA which is already defined on your iPhone.Cybertrust Educational CA
The name on the SSL certificate presented by the authentication server at your home site e.g.
The username you use to authenticate against your home account. Note the inclusion of your domain name e.g.
The password you use to authenticate against your home account.mypassword

  1. A "Verify Certificate" pop-up window will display on your screen.
    Click Show Certificate
  2. Compare the details shown against those certificate details provided by your home site, as described earlier:

    If CA certificate name (in the upper pane) matches Cybertrust Educational CA and SSL certificate name (in the lower pane) matches, then do the following to proceed with your wifi connection:
    Select Always trust ""
    Click Continue

    Otherwise, click Cancel to disconnect from this potentially fake server and report the incident to your home site as soon as possible.

If you follow the instructions above then this manual verification step will happen once only, and on subsequent connections to eduroam you will not need to repeat this verification process.
