If you use Linux and PasswordBox and are now being prompted to migrate, don't! Where PasswordBox was a platform agnostic service using browser plugins/extensions in combination with mobile devices, TrueKey is not. If you migrate from PasswordBox to TrueKey, you will not being able to access your passwords from a Linux workstation. If you're lucky enough to know someone with an Windows of Apple PC, you can use their workstation to export to JSON and move it from their machine to yours (don't email it because that defeats the purpose). Then you can parse that JSON and convert it to work with any of the dozens of password services that are still platform agnostic.

I've been on the phone with Intel (seriously Intel??) support a couple times now and I've moved through a number of people. They do not have a rollback procedure. Once you're migrated, it's over. They don't have Linux support (maybe I'm their only customer using Linux) and have no way of solving this problem.

If I can save one person from learning it the hard way, I've done my job. Yay backups!
