You can encrypt emails on almost any device. In this article, however, I will be focusing on Gmail, Outlook, Yahoo. I will also be focusing on making ProtonMail encrypt emails with Gmail.</p><h2><iclass="fa fa-fire"aria-hidden="true"></i>Myths</h2><p>Firstly, let us dispell a few myths. The first myth is a big one.</p><h3>Gmail's Confidential mode does not encrypt your emails</h3><p>Yes, you heard that right. Gmail's confidential mode does not encrypt your emails. Whenever I speak about email encryption, I hear something along the lines of:</p><p><em>“Why are you making things so complicated? Just use Gmail's confidential mode! It encrypts your emails for you!”</em></p><p>No, Gmail's confidential mode does not encrypt emails.

Afterwards, you can import their public keys. Henceforth, all emails will be encrypted. Many websites also give their own public key along with their emails so that you can encrypt them as well. If you have friends who use ProtonMail, go to the ProtonMail import section of this post.</p><h3>Step 4: Send encrypted emails!</h3><p>Whenever you go to compose an email, there will be a button like the image below.
