About Digital Certificates
Yes. Digital certificates expire after one year and cannot be renewed. Each year, you can apply for a new digital certificate.
NHSN will notify you via email 30 days prior to your digital certificate's expiration date. This email will include instructions on how to proceed, including the website and password.
NOTE: You should not apply for a new digital certificate prior to receiving the notification from NHSN.
That's okay. You can still apply for a new digital certificate, using the website and password included in the email from NHSN. Once a digital certificate has expired, however, you will not be able to access NHSN until a new digital certificate is installed.
No. Once you have applied for a new digital certificate, your expiring digital certificate will no longer work. You should receive your new digital certificate within 48-72 hours of applying.
Instructions for installing a digital certificate can be found in the User Start-up Guide [PDF - 433 KB] October 2011. A step-by-step start-up guide for NHSN Users who are not Facility Administrators or Group Administrators. Step 3d.
No, you are not required to create a new challenge phrase. You can use the same challenge phrase from your expired digital certificate.
