Email Encryption and Signature Services FAQs

  • 1. I want to use MeSign APP, is it necessary to register my MeSign account in MeSign APP website?


    No. You don't need to register for our Services. Your email address will be used as username (account name) in our system automatically. You can log into your account in MeSign APP website to check your account information, set and reset your certificate protection password, revoke certificate and lock MeSign APP on any of your device.

  • 2. What should I do to delete my MeSign APP account?


    You may delete your MeSign APP account at any time by logging into your MeSign APP account in MeSign APP website. Uninstall your APP doesn't mean you have deleted your account. Your email will be in the "unsubscribed list" that other MeSign users can't get your encrypting certificate and can't send encrypted email to you after you delete your account. MeSign APP will delete your account data and revoke your Account Certificate within 5 work days after you submit the account deletion request.

    Please note: After your account is deleted, you will not be able to log in to your MeSign APP account and you will not be able to use MeSign APP. Please uninstall the installed APP. Since the encrypting certificate has been revoked, you may not be able to decrypt the encrypted message using other S/MIME email client software.

  • 3. How can I recover a deleted account?


    If you want to recover a deleted account, please visit MeSign APP website, go to here to re-register your account.

    Please note: the new configured encryption certificate can’t decrypt the encrypted email that encrypted before account deleting since we completely delete your former encrypting certificate.
