Deleting saved login data in Linux

In Linux, the location where passwords are stored depends on the desktop environment you are using (e.g., GNOME or KDE). Many programs access a central “keychain,” but others store passwords internally.

Option A: GNOME (Ubuntu, Fedora, Debian, etc.)

The default management tool in GNOME is called “Passwords and Encryption” (technical name: Seahorse).

  1. Open the application: Press the Superkey (Windows key) and type “Passwords” or ‘Seahorse’. Open the “Passwords and Encryption” application.
  2. Find entries: Look in the left bar under “Passwords” in the ‘Login’ folder.
  3. Filter: Use the search function (magnifying glass) to search for entries such as “Exchange”, “tuwien”, or “uptudate”.
  4. Delete: Right-click on the corresponding entry and select “Delete.”

Option B: KDE Plasma (Kubuntu, OpenSUSE, etc.)

KDE uses the KDE wallet (KWallet).

  1. Open application: Open the application menu and search for “Wallet” or “KWalletManager”.
  2. Open Wallet: In most cases, you will first need to enter the password for the wallet to view its contents.
  3. Search: Search the folder structure for entries labeled “Mail”, “Exchange”, or “tuwien”.
  4. Delete: Select the entry, right-click on it, and select “Delete.” Then save the changes.

Important information for Linux users!

Thunderbird & browsers: Under Linux, programs such as Thunderbird, Firefox, and Google Chrome often do not use the system keychain, but instead store passwords in their own database.

  • Thunderbird: Go to Settings → Privacy & Security → Saved Passwords. Search for “tuwien” and delete the entries.
  • Evolution Mail: Usually uses the GNOME keychain (see option A).
