- Q. How does Cardinal Key protect my computer?
- A. Cardinal Key ensures that devices meet our MinSec requirements (per MyDevices) regardless of location.
- Q. Why does Safari always prompt me to select which Cardinal Key to use when I authenticate to a Stanford website?
- A. You can eliminate the prompt by associating an "identity preference" with the certificate in the Keychain Access app.
- Open the Keychain Access app by navigating to Applications > Utilities > Keychain Access.app.
- In the Keychains section, click login and then in the Category section click My Certificates.
- If there's more than one Cardinal Key, you might want to delete older ones before proceeding. This isn't necessary but can reduce confusion and clutter.
- Right-click the Cardinal Key certificate you want Safari to use and then click New Identity Preference.
- In the New Identity Preference Location or Email Address field, enter https://login.stanford.edu/ and click Add.
- Q. Why does my Cardinal Key stop working after two days?
- A. Devices must be compliant in MyDevices in order to use the Cardinal Key service. This rule applies to all users, regardless of affiliation. There is a two-day grace period after the initial installation of a Cardinal Key during which it may be used on a non-compliant device, or on a device whose compliance status is unknown. Once the grace period expires, the Cardinal Key will become unusable until the compliance problem is addressed.
- Q. How does Cardinal Key protect against phishing?
- A. Using Cardinal Key means no longer being prompted for a SUNet ID and password. If you DO encounter a Stanford-looking login page asking for a username and password while using Cardinal Key, you should be suspicious of a phishing attempt.
- Q. I have Cardinal Key installed on my device. Why am I still being prompted for two-factor authentication?
A. Cardinal Key replaces the need to provide your SUNet ID and password. Depending on the system, the frequency may vary, but you will still need to two-factor in. Learn more about two-step authentication.
- Q. Which Stanford sites require me to log in with a Cardinal Key?
- A. The campus-wide Cardinal Key rollout is to enforce the use of Cardinal Key when logging into webmail.stanford.edu, axess.stanford.edu, and Google Docs (this would include *.google.com).
- Q. Why can’t I join the eduroam network with my Cardinal Key?
A. You must use a Cardinal Key installed after January 2021 in order to join the eduroam network. You can use the Cardinal Key installer (ckinstall.stanford.edu) to install a new Cardinal Key.
- Q. Cardinal Key works fine on all my browsers, but I cannot log in to VPN with it. What should I do?
A. When logging into the VPN, please make sure you are selecting the Cardinal Key instead of another certificate. Learn more:

- Q. Why did my Cardinal Key stop working in Firefox?
A. Make sure Firefox doesn't have the following authentication decision saved:
- Open the Firefox Preferences by navigating to Firefox> Preferences > Privacy & Security > View Certificates > Authentication Decisions.
- In the "These certificates are used to identify you to websites" window, select the line that shows login.stanford.edu and Send no client certificate.
- Click Delete.
- Click OK.
- Q. Can I install Cardinal Key on a personal device?
A. Yes, you can install Cardinal Key on a personal device. In order to use the Cardinal Key past the initial 48 hour grace period, that device needs to be compliant in MyDevices.
- Q. Can I store High Risk Data in Google Drive using Cardinal Key?
A. Yes, follow the instruction on this page to learn more.
- Q. Can I install Cardinal Key on a shared device?

- Q. Which Stanford sites can I log in with a Cardinal Key?
A. Any Stanford site that supports SAML can be set up by the administrator to recognize the Cardinal Key. Please submit a Help request to the Information Security Office for more information.
