Proton Technologies is a company specializing in the development of various high-security products. The company’s most well-known product is Proton Mail, a mailbox service that supports end-to-end encryption.
Proton Mail can be easily authenticated and used on the web, but it may be difficult for professional users or users who need to use the client, because Proton Mail on the Linux platform cannot be directly connected to the mail client based on product encryption architecture issues, such as if you login directly in the Thunderbird client, an error will be reported directly.
After a period of development, the company has launched the Proton Bridge platform for the Linux operating system. You can simply understand it as a bridge between the Linux mail client and Proton. With the help of a platform such as Thunderbird client, you can use IMAP/SMTP protocol to connect to Proton Mail and continue to enjoy high-security end-to-end encryption services.
Proton Technologies stated:
ProtonMail Bridge is a desktop app available to all paying subscribers that integrates ProtonMail’s strong privacy and security features, such as zero-access encryption and end-to-end encryption, with your email client.
Your client stores a copy of the emails on your computer, enabling you to search their content. This also allows you to load emails for offline reading and processing. We are working on launching encrypted, full-text search and offline reading soon for the web and mobile applications.
