Important: Clearing cookies will sign you out of websites. Removing saved passwords will delete credentials stored in your browser and may also affect other devices if password synchronisation is enabled. Make sure you know your passwords before proceeding.

Security reminder: Never follow instructions from a website that you don't understand, particularly instructions asking you to open Windows PowerShell, Command Prompt, or Run, copy and paste commands, or download and install software. If you're unsure, contact your IT support team before proceeding.
