To read the message, they must enter a previously agreed-upon password. With Password-protected Emails, the person you’re writing to receives an email telling them they’ve been sent a secure encrypted message. It’s a way you can send a secure, end-to-end encrypted email to anyone who isn’t on Proton Mail. What is a Password-protected Email?Ī Password-protected Email is an email that requires a password to open it. You can also use PGP encryption if the person you’re writing to uses it. If you want to send a secure, end-to-end encrypted email to someone who isn’t on Proton Mail, the easiest way is to use a Password-protected Email. While ProtonMail is a useful if not perfect encrypted email client, the company reminds users, as always, that encrypted email won’t save you if anyone gains access to your device itself.Emails sent between Proton Mail users are automatically end-to-end encrypted.

ProtonMail notes that Bridge users will enjoy some added convenience, including the ability to do full body text searches and to manage multiple accounts. “Use email like you have always used it, and the Bridge will automatically encrypt and decrypt messages in the background.”

“The best part is that this does not require modifying your email client or making changes to your existing workflow,” the company writes in its announcement. The process maintains the core offerings of ProtonMail: end-to-end encryption, meaning that only a sender and receiver can view an email, and zero-access encryption, meaning that the email provider can’t see your emails even if it wanted to. Now, users loyal to common mail clients Apple Mail, Thunderbird, Outlook or anything else that supports IMAP and SMTP can run ProtonMail Bridge in the background to enable a ProtonMail account to play nice with one of those newly supported clients. ProtonMail, built around the encryption standard known as PGP (Pretty Good Privacy), previously required users to use its own apps or webmail service. ProtonMail just introduced a new tool, called ProtonMail Bridge, that could expand its relatively niche appeal to more mainstream users who aren’t yet comfortable with giving up their email client habits. Robot’s email service of choice just expanded its support for a handful of popular email clients.
