Is there a 1password portable for windows?
There is not.
If you use Dropbox to sync your 1Password data to another computer or other device, you can open your .agilekeychain folder on your private Dropbox web site, double-click 1Password.html (a.k.a. the 1PasswordAnywhere file), and provide your master password to view your 1Password data.
You can also copy your entire .agilekeychain folder to a portable drive and carry that to other computers, opening the 1PasswordAnywhere file on that portable copy to view your 1Password data.
I hope that helps, @Kylereilly. Please let us know if you have any other questions.
