Renewing a Certificate

Your certificate will need to be replaced when it expires. You will use the same process to replace the certificate as you did when you created the original certificate.

The new certificate will be generated and saved on your computer. If you have used your old certificate to encrypt data files, then you should keep it, but otherwise it can be removed.

Finding the Expiration Date

Click Advanced from the Menu bar, then the Certificate & Keys tab. The Valid to field will show the expiration date of the certificate on your eToken.
