Create Portable Password Manager
Click on "Settings" in the menu bar and then on the button "Portable Password Manager". Select the location where you want to create the Portable Password Manager. Usually that will be a USB thumb drive. Now select the keychain you want to copy frothe dropdown menu and then click on "Create".
To use the Portable Password Manager on another PC, just connect that USB stick and open it. On the USB stick there is a file named PasswordManagerPortable.exe. Double click on that file: the Password Manager opens and you can enter your password in order to access your keychain.
Hint: By default only one keychain can be copied onto a USB stick, a second keychain saved on the stick will overwrite the first. If you want to save several keychains on the same stick, you have to change the file name, e.g. by adding the name of the keychain. That way you are able to transport a file named PasswordManagerPortable_Office.exe and one named PasswordManagerPortable_Privat.exe and access two different keychains on another PC. The functionality of the exe file is not affected by renaming it.
