Contact UsWhat is an S/MIME certificate, and why do I need one?
How do I install an S/MIME certificate on my email client?
emSign provides a step-by-step guide for various email clients. Generally, you'll need to download the certificate from emSign, open your email client settings, and import the certificate into your "Certificates" section. Specific instructions will be sent to you along with your certificate.
How long does an S/MIME certificate from emSign last?
S/MIME certificates typically have a one-year validity, after which they must be renewed. emSign will notify you when it's time to renew, ensuring uninterrupted email security.
Can I use one S/MIME certificate for multiple email addresses?
No, each S/MIME certificate is tied to a specific email address to maintain individual authenticity and security. If you need protection across multiple addresses, you'll need separate certificates for each.
What happens if I lose access to my private key?
The private key is essential for decrypting messages and digitally signing emails. If you lose it, you will no longer be able to access encrypted emails or sign messages. emSign recommends securely backing up your private key. In the event of loss, you may need to request a new certificate.
How do I renew my S/MIME certificate with emSign?
Simply log into your emSign account, select the certificate you wish to renew, and complete the verification and payment steps. emSign will then issue an updated certificate for uninterrupted service.
Are emSign's S/MIME certificates compatible with all email clients?
