Stop clipboard anxiety before it becomes a leak.
AFKClipboardGuard helps protect copied passwords, tokens, JWTs, API keys, and other sensitive text on Windows. It watches the clipboard locally, clears it automatically, detects likely secrets, and can move critical data into a protected local vault.
AFKClipboardGuard runs in the tray, uses clear Windows toasts for important events, and stays invisible when nothing risky is happening.
What it protects against
Secret exposure
Passwords, tokens, private keys, JWTs, and high-entropy secrets left in the clipboard longer than needed.
Clipboard History / Cloud Clipboard
Warnings when Windows clipboard features may increase exposure or sync copied data further than expected.
Suspicious clipboard changes
Alerts when the clipboard changes without recent user input, helping surface malware-like or unexpected behavior.
Auto-clear
Clear the clipboard after a timer, after paste, or immediately for higher-risk content.
Secret detection
Detects tokens, passwords, JWTs, PEM private keys, and other likely sensitive strings.
Secure vault
Move critical secrets out of the clipboard into a local encrypted vault protected by Windows DPAPI and optional PIN.
Per-app rules
Apply stricter behavior in selected apps such as remote desktop tools or other sensitive contexts.
How it works
1. You copy something sensitive
AFKClipboardGuard analyzes clipboard changes locally and decides whether the copied text looks like a secret.
2. It reacts based on your rules
Depending on your settings, it can warn you, clear the clipboard, store the secret in the vault, or apply app-specific policy.
3. You stay in control
Everything is configurable from the tray settings: timers, detection sensitivity, PIN, privacy checks, secure paste behavior, and startup options.
