App

Will this program steal my accounts?

No, if you download from official releases or build the source yourself.

Account switching swaps local login state and asks for no password at all. One optional feature, Steam Guard, does take your Steam password, because signing in to Steam needs one. That password is encrypted with a key fetched from Steam, sent to Steam, and never written to disk. What gets stored is the session Steam issues in return, encrypted under a separate Steam Guard password you set.

Token files copied to LoginCache stay on your machine unless you share them or malware reads them. See the Privacy Policy.

Does Microsoft Edge WebView2 install the Microsoft Edge browser?

No. WebView2 is a shared runtime used to render the app UI. It is separate from the full Edge browser.

Can I put this program on a USB?

Yes.

1. Extract the portable .zip or .7z to the USB drive.
2. Run TcNo-Acc-Switcher.exe.
3. Optional: set Settings -> System -> User data location to a folder on the USB drive.

Notes:

• Platform login tokens are usually tied to the Windows machine. Another PC may ask for passwords again.
• Keep the drive letter stable if settings contain absolute paths.
• WebView2 must be installed on each Windows PC.
• If {exe folder}\TcNo Account Switcher\ exists, the app uses it as portable user data.

The TcNo Account Switcher is blue on launch. Can't interact.

WebView2 is missing or broken.

1. Install WebView2 Evergreen.
2. If WebView2 is already installed, repair Microsoft Edge/WebView2 from Windows Settings.

CEF is no longer used.

How do I completely reset / wipe / clear cache for the switcher?

Open the user data folder. Default: %AppData%\TcNo Account Switcher.

Path	What it stores
LoginCache/	Saved accounts and swapped files
Settings/	Per-platform settings
TcNo-Acc-Switcher.settings.json	App settings
wwwroot/	Custom backgrounds
WebViewCache/	WebView2 cache
Platforms.json	Live platform catalog
Platforms.custom.json	Local platform overrides
GameStats.custom.json	Local game-stat overrides
CrashDump.json	Last crash context, if present
Statistics.json	Local usage stats
Tray_Users.json	Tray recent accounts
img/profiles/	Cached avatars

Delete only the data you want reset. The install folder is separate.

How do I clean reinstall the TcNo Account Switcher?

1. Uninstall from Windows Settings if you used the installer.
2. Delete the install folder. Default: C:\Program Files\TcNo Account Switcher.
3. Delete the user data folder. Default: %AppData%\TcNo Account Switcher.
4. Install the latest build from Releases.

The current app does not need _FIRST_RUN.exe or .NET.

Switching

I need to enter a password every time I switch

Use Add New in the switcher. Do not use the launcher's sign-out button.

Steam and Battle.net can detect saved accounts, but each account still needs the launcher's remember-password option enabled.

For most other platforms:

1. Click Add New.
2. Sign in and choose the platform's stay-signed-in option.
3. Quit the platform cleanly.
4. Click Save Current.

VPNs, HWID spoofers, disk cleaners, and privacy tools can invalidate remembered logins.

My accounts aren't switching

1. Confirm the platform closes during swap.
2. Close it manually and swap again.
3. Change Platform -> Settings -> close method between Combined, Close, and TaskKill.
4. Verify the launcher exe path in settings.
5. Search Common errors for the toast text.
6. Check {UserData}/Platforms.json; launcher updates can move files.

How do I manually remove accounts from the TcNo Account Switcher?

Open {UserData}/LoginCache/{Platform}/.

• Delete account folders for templated platforms.
• Edit ids.json or order.json only if you need exact list cleanup.
• For Steam, use Forget or edit loginusers.vdf.

This removes switcher entries. It does not delete the real service account.

Steam

Failed to load loginusers.vdf

1. In Steam -> Settings, confirm the Steam folder.
2. Check {Steam}\config\loginusers.vdf for broken VDF syntax.
3. Restore loginusers.vdf_last from the same folder if it exists.
4. Last resort: delete loginusers.vdf and add each account again through Add New.

Valid shape:

"users"
{
  "76561197960287930"
  {
    "AccountName"        "login_username"
    "PersonaName"        "DisplayName"
    "RememberPassword"   "1"
    "mostrecent"         "1"
  }
}

I forgot my Steam Guard vault password

There is no reset. The app holds no copy of the key.

If you enrolled a backup key, keyfile or security key, unlock with that and set a new password under Steam -> Settings -> Steam Guard -> Manage. If you have a backup folder made while you still knew the password, restore it. Otherwise the records in that vault stay encrypted.

Your Steam accounts are separate from the vault. Steam's own recovery code, shown once during setup, is what removes an authenticator; account recovery beyond that is Steam Support's process. See Steam Guard.

I need to enter a password every time I switch - Steam

Check the general password advice, then check Steam:

• Disable Don't save account credentials in Steam account settings.
• Avoid tools that delete Steam login files.
• Use Advanced Cleaning only when you intend to sign in again.

See Steam's interfering programs list.
