# App-Password Automatic Loading

**App-Password Automatic Loading** is an authentication technique used by the [[nc-connector]] to establish a secure connection between Mozilla Thunderbird and a [[nextcloud]] instance.

## Mechanism
Instead of requiring the user to manually generate and enter an application-specific password within the Nextcloud settings, this method:
1. Triggers a request to open a web browser.
2. Redirects the user to the Nextcloud login page.
3. Requests authorization for the extension to access the account.
4. Automatically retrieves and configures the necessary credentials (app password) back into the Thunderbird extension.
