In plain English
It is a spare sign-in code for times when the normal identity check cannot be used. Its role is to confirm who the person is during sign-in.
In context
Here, "backup code" refers to an alternative code option for verifying identity during sign-in when the usual verification method is unavailable.
- Situation

Meaning limits
The term alone does not establish that sign-in will succeed, only that the code can be used to verify identity in that situation.
