Obtain an Email Certificate

Before you can use your PassKey with Thunderbird, you need to obtain an email certificate from a Certificate Authority (CA) and associate it with your PassKey. The certificate is stored in WWPass secure cloud storage, where it cannot be stolen. Click here for more information.

The CA can be:

• A third-party CA such as Comodo—Click here for instructions on obtaining a certificate from Comodo. In most cases, the certificate is automatically associated with your PassKey. However, on some operating systems, it is downloaded as a file first. Click here for instructions on importing a certificate file and associating it with your PassKey.
• Your organization's CA—Ask your system administrator for information about obtaining a certificate. Your organization might issue certificates using Microsoft Active Directory Services or it might email you a certificate in a file.

A certificate from a third-party CA is trusted for all email you send. A certificate from your organization is trusted for email you send to people within your organization.

After an email certificate is associated with your PassKey, it is shown in Thunderbird’s Certificate Manager while your PassKey is presented to your computer. The certificate is cleared from Certificate Manager when your PassKey is removed.

Next: After you obtain an email certificate, you can select it in Thunderbird for use with digital signing and encryption.
