Improving the user experience when using the MFA backup code.

Currently, a 14-character code is generated that includes 2 spaces.

Users need to know that the spaces must be entered—which isn’t very intuitive.

We would like the string to be continuous or separated by hyphens.

For the client, it would be preferable if the input were structured into fields of 4 characters each. 

This way, the spaces or hyphens could be automatically inserted, making the input process more intuitive for the user.
