ProtonMail Revamps “Bridge” Utility for Using Third-Party Mail Apps
ProtonMail is an end-to-end encrypted email service, adding an extra layer of security on top of traditional email. Additional security features mean you can’t connect a ProtonMail account to a third-party email app like you can with Gmail or Yahoo accounts. ProtonMail’s solution to this is the ProtonMail Bridge app, which has been around for a while, but has now received a significant update.
ProtonMail wrote in a blog post, “We’ve redesigned ProtonMail Bridge to give you better insight into your account(s) and revamped our settings so you can now easily control your cache location or reset the app. also comes with dark mode! […] This new version of ProtonMail Bridge is packed with fixes and improvements, but the main change is the new local cache, which now includes full message bodies. This means that ProtonMail Bridge stores encrypted messages on your device, so they can be retrieved much faster than when stored remotely on our servers.
ProtonMail Bridge, as the name suggests, acts as a bridge between an email client running on a computer and ProtonMail’s servers. The utility configures a local mail server to which mail clients can connect, and end-to-end encryption is maintained between ProtonMail and the local server. This way, you can use apps like Thunderbird or Apple Mail with one ProtonMail account, while using these clients with other accounts. However, the bridge is still not available for mobile platforms, so iOS or Android users are still tied to the official ProtonMail mobile apps.
ProtonMail Bridge is available for download for Windows, macOS and Linux (in DEB and RPM format). The update is rolling out slowly to anyone who has ProtonMail Bridge installed before, but you can also force the update by downloading the installer again. Unfortunately, ProtonMail Bridge still does not work natively on Mac computers with Apple M1.
