How to open a secure email?

If you have received an encrypted message from an organization that uses Seald, there are two ways for you to open it. You can either sign up to Seald to open all the encrypted message seamlessly (discover Seald) or you can follow this procedure to authenticate yourself for a short period.

Before you begin

What is Seald?

Seald encrypts your emails, attachments and documents seamlessly. An easy-to-use cryptography solution designed for companies, different from other existing tools by its user-friendliness and accessibility.

I already have a Seald account. Do I need to follow this procedure to view an encrypted message?

No. This process is only for people who have not installed Seald yet. Open the document on the computer with your existing account to view the encrypted message.
