Bridge your iCloud Keychain to Windows.

Use your iPhone to fill out passwords on your PC.

WinchPass is a Chrome extension intended for users of iCloud Keychain that have a Windows PC.
It fills out passwords automatically and doesn’t keep any data.
It uses one-time pad encryption and QR codes to link your phone to Chrome.
Once the password is filled, the encryption key is discarded and cannot be reused.
