Mail Backup X OAuth Helper: Seamless Sign-ins
The Mail Backup X OAuth Helper works hand-in-hand with your Mail Backup X application. Since Mail Backup X uses OAuth for secure sign-ins with popular email services, and your application might be running on a custom local network setup, this extension plays a vital role. It makes sure the OAuth response gets routed correctly to your Mail Backup X application, allowing your sign-in process to finish smoothly every time.
