For discussion around this see: https://pagure.io/fedora-workstation/issue/82 Recovery keys for homed are very similar to regular passwords, except that they are exclusively generated by the computer, and not chosen by the user. The idea is that they are printed or otherwise stored externally and not what users type in every day. Taking inspiration from Windows and MacOS this uses 256bit keys. We format them in 64 yubikey modhex characters, in groups of 8 chars separated by dashes. Why yubikey modhex? modhex only uses characters that are are located at the same place in western keyboard designs. This should reduce the chance for incorrect inputs for a major chunk of our users, though certainly not all. This is particular relevant during early boot and recovery situations, where there's a good chance the keyboard mapping is not correctly set up.
