Frequently Asked Question
You must always have at least two working USB-keys. They should not be stored in the same building, in case of a burglary (or fire).
Make sure the USB is FAT32 formatted, then it will work with both Linux, Windows and Mac OS.
Do NOT try to make your own copy, by copying the files or by creating a diskimage. This will make the original stop working!
(Note 1: If you are using a previous corrupted USB, format the corrupted USB key as a FAT32 partition first!)
(Note 2: Activating a second USB will not affect your IMAP-key)
