Locked Up Mail works in 3 simple steps:
1. Sign up with a username and password. A quick response (QR) code will be generated for you.
2. Print out the QR code before it expires. You’ll have 10 minutes. (Feel free to make copies—there’s no way into your email without it.)
3. To login, scan the printed QR code and enter your password.
And that's just the beginning: encrypted emails, fraud protection and more all included.
