Yes, MyPadlock will work great on all versions of Windows. Please note that the new Microsoft Edge web browser does not support dragging your login from MyPadlock into the fields in the browser. That said, Internet Explorer, Chrome, FireFox, and other web browsers still support this and all other features work the same that they did on previous versions of Windows.
NEW: There is a brand new version of MyPadlock just for Windows 10. If you are interested in helping test, you can get MyPadlock for Windows 10 from the Windows 10 Store.
Yes. To support this, please copy your .MyPadlock file (by default it is created in your Documents folder) onto your USB thumb drive. Then, go to the MyPadlock settings window in the app (click the little wrench icon in the upper right after logging in) and browser for your password file on your thumb drive. Once complete you can restart the app and then remove the original file from your Documents folder.
Open MyPadlock, log in and go to the MyPadlock settings window in the app (click the little wrench icon in the upper right). From here you can export your passwords to a text file that Microsoft Excel can open. Please note, the expored file is not secure and should be destroyed when you are done using it.
To backup, you can simply make a copy of your .MyPadlock file (by default this called Passwords.MyPadlock and saved to your Documents folder). However, this is encrypted so you will need MyPadlock to open it again. Alternatively you can export your file to a .csv (comma delimited file) that you can open in a text editor or spreadsheet program like Excel. To do this, click on the little wrench icon in the upper right after loging in and then click the Export button. Keep in mind, with this later approach the file will not be encrypted and is therefore not secure. To keep it secure, we recommend storing it on a USB thumb drive that you can then store in a secure location.
The first thing to understand is that there are two different kinds of apps that can run on Windows 10. The first kind are traditional (or Win32 apps). These have been around for many years and get installed by downloading from the internet or an external disk. The second and newer kind is a "store" app which you can get from the Windows Store (introduced with Windows 8). A store app imposes greater restrictions on what the app can do in the interest of security. For example, when you install a traditional Win32 app, that app technically has the potential to do malicious things to your computer such as install viruses. With traditional Win32 apps, the burden has always been on you as the user to make sure you trust a particular app before installing it. Whereas apps from the Windows Store are restricted to a point that it would be technically impossible for the app itself to do certain malicious things such as install other software or scan your hard drive. Microsoft is increasingly pushing users to use store apps instead of traditional Win32 apps and does this by being louder about warnings when installing the traditional Win32 apps. Put another way, installing traditional Win32 apps on Windows 10 is no less secure than it was on Windows 7 or 8; Windows 10 just makes a greater fuss about it in hope that you will rethink installing it and look for an equivalent app in the store instead. MyPadlock is a traditional Win32 app since it was created prior to the existence of Windows 8. However, we already have a new beta version for a Windows 10 store app that users will ultimately be encouraged to switch too once it is ready. If you are interested in helping test, you can download the Windows 10 store version of MyPadlock.
Unforunately, there is nothing you can do but start over. Your passwords are encrypted with your master password which means that without it, there is no way to retrieve the passwords saved by MyPadlock. This can be a hard pill to swallow but this is also the very reason why MyPadlock is so secure. To start fresh with MyPadlock, you can remove (or rename if you think you might remember your password someday) your Passwords.MyPadlock file which is stored in your Documents folder by default. After doing so, you can restart the app and it will create a new blank file and ask you for a new master password... be sure to remember your new one!
