App Sessions
App Sessions store website sign-in state. YouTube, YouTube Music, and some downloads that require account access use these sessions. You can sign in through XiaDown or explicitly sync from a supported local browser.
Open Library → App Sessions.
Sign in through XiaDown
Section titled “Sign in through XiaDown”- Select a website from the list.
- Click Connect or Reconnect.
- Complete sign-in in the opened browser.
- Return to XiaDown and click Verify Sign-in.
- After verification succeeds, reopen the corresponding feature or download window.
Sync from a browser
Section titled “Sync from a browser”- Click Sync from Browser at the top of App Sessions.
- Select a supported local browser.
- Choose how to read it: authorize access to the current Chrome session, or copy and parse the selected local browser profile.
- Follow the page’s instructions for prerequisites such as remote debugging, system permission, or closing the browser, then scan the profile.
- Review the accounts found, select the ones you need, and sync them.
XiaDown reads only the sign-in data needed by supported apps from the selected source and does not modify the browser profile. You initiate every sync explicitly.
Common actions
Section titled “Common actions”| Action | Result |
|---|---|
| Search | Find a target website quickly. |
| Sync from Browser | Sync supported sign-in state from a local browser profile you choose. |
| Verify Sign-in | Check whether a saved session is still valid. |
| Reconnect | Open the sign-in process again. |
| Sign Out | Clear the session XiaDown saved for this website. |
Use a session for downloading
Section titled “Use a session for downloading”After an App Session is verified, New Download may show “App Session available.” Enable Use App Session to download with access already granted to the current account.
A session cannot bypass site rules. Only access and save content you are authorized to use.
Local storage
Section titled “Local storage”- On macOS, App Sessions are stored in the system Keychain. The system may ask you to confirm access the first time they are read after an upgrade.
- On Windows, they are stored in XiaDown app data using encryption tied to the current system user.
XiaDown does not automatically read sign-in state from your everyday browser in the background. It reads the necessary data from a selected source only after you explicitly choose Sync from Browser. Signing out of an App Session does not sign you out in other browsers.
When a session expires
Section titled “When a session expires”Websites expire sign-ins periodically. If a feature requests sign-in, reports an expired session, or lacks permission, verify the session first and reconnect only if verification fails. macOS users should also check whether Keychain access was denied.
