Why “World’s Strongest?” – How “Passmado” Protects Your Windows PC
“Passmado” replaces password-based sign-ins to Windows PCs with a “Password changing over a certain period of time” [* 1].
This “password that changes over a certain period of time” is displayed in the form of a 5 x 5 lattice-like grid (matrix) in the smartphone app “PassClip” [* 2].
“Passmado” is a mechanism (knowledge authentication software) that only the person who knows a correct “pattern” (Chosen by the user) can derive the dynamic one-time password.
Furthermore, after displaying the password with PassClip, it unlocks [* 3] for 60 seconds. If the device is locked, it will not accept sign-ins (possession authentication).
In theory, this two-factor / two-way authentication of “pattern storage” and “unlocking” completely prevents against authentication-related hacking.

Why “World’s First” – The Culmination of Passlogy’s Patented Technology
“Passmado” is the mechanism of two-factor / two-way authentication and uses a patented technology which is publicly recognized as state-of-the-art.
Therefore, the Windows Sign-in Protect Service with “Passmado” will be the world’s first service of its kind and offered only by Passlogy.

[*1] Password changing over a certain period of time: Japan Patent No. 6207797
[*2] Display password in the form of a 5 x 5 lattice-like grid: Japan Patent No. 5276658
[*3] Unlock over a certain period of time: Japan Patent No. 5906363

Assumed Users of “Passmado”
We assume that “Passmado” can be used for Windows PC individual users as shown below.

-Assumed User Case 1: Users Who Emphasize Data Protection in Windows PCs
Any solution for enhancing the windows sign-in with a second authentication factor requires a second device and some effort. However, Passmado/PassClip provides not only strong authentication but it’s user friendly and comfortable compared to other two-factor authentication solutions. It’s beneficial to those who keep important data on the Windows PC, who share a single PC with multiple people, and all those who are not good at memorizing static passwords.

-Assumed User Case 2: Windows Remote Desktop Users
When using “Remote Desktop Connection” (standard function in Windows 10 Pro) on your Windows PC at home or in a private location and installing “Passmado” on the remote destination PC, a secure sign-in environment can be realized.
In Remote Desktop Connection, the connected PC can be accessed at all times and hacking is a major issue. However, if you use “Passmado”, the smartphone lock function makes it secure to completely prevent unauthorized sign-ins. In the case of Remote Desktop Connection, which tends to be hacked, “Passmado” can be a powerful solution.

Supported Environments
“Passmado” works on Windows 7, 8.1, 10, with support for 32-bit and 64-bit versions and is certified as safe software with Microsoft code signing certificate. It is also possible to install “Passmado” on multiple Windows PCs and manage them with one smartphone.
In addition, each can be managed with a common password or can be managed with separate passwords.
Free software “Passmado” is for personal use only. There is no enterprise version.
