WipeAway sessions are valid for 24 hours after you sign in. After that, you will need to sign in again with your Google account.
Session expiry is a standard security practice. It ensures that if someone else gains access to your browser or device, they cannot access your WipeAway session indefinitely. The 24-hour window is intentionally short for security reasons.
