Is it possible to have a portable version of Proton Authenticator?
I would like Proton Authenticator to be runnable directly from a USB drive, with no data stored on the host computer, and with all sensitive information securely encrypted inside the application’s own directory (e.g. <usb_drive_root>\ProtonAuthenticator.UserData\EncryptedUserData.db).
Other applications, such as Firefox, already provide a fully portable mode that can be executed entirely from a USB drive. Having a similar option for an authentication app would significantly improve security when using shared devices or when you don’t want to leave sensitive data on the system.
This feature would also make data backup much simpler.
