About Hydronium

Hydronium is an app that allows you to connect to Proton Mail on Ubuntu Touch using any email client. It installs and runs the Proton Mail Bridge locally, and provides a friendly UI for configuring the bridge and adding your account(s) to it. Full system access is required to manage the bridge service. Make sure to follow the how-to in the app for correctly configuring your e-mail client.

Supports:
- Regular login.
- Login with 2FA token/TOTP.
- Login with secondary inbox password (supposedly; untested).
