About QRPasswds
Use QRPasswds to securely store your passwords in a QR image only you can read.
Your passwords are encrypted with a 128-bit AES key that is randomly generated on the first launch and then stored in your phone. Nobody can read the QR image without that key. Even if they scan it with a QR reader, they only get random characters.
You can import/export the keys to use it with multiple devices

Does what it says. Import/export key is useful if you have many devices and scan from file makes things quicker. I recommend it.
