    - The Priority Service guarantees the issue of the certificate on the same day, after receiving the documentation and payment confirmation. Check here the details of this service.

    - PDF Sign & Seal is an application that allows you to create and digitally sign documents in PDF format. See the PDF Sign & Seal requirements here.

    - In the PDF Sign&Seal application, simultaneous document signing is not possible for digital certificates in CLOUD, because they require specific authentication for each use/subscription.

    - The digital certificate is generated and stored in HSM (Hardware Security Module), therefore, it can not be exported or reproduced in another device after being issued;

    - The use of your certificate (for each signature) requires 2 (two) authentication factors: the password you set at the time of purchase and a random code sent by SMS to the confirmed mobile phone number during the online validation;

    - There are no password recovery mechanisms for security reasons. You can change your password as long as you know your current password. If you lose your password, the certificate is lost and can not be recovered.
