The way it’s meant to be done:

1. You register both the primary and the backup key with every identity provider (ie GitHub)

2. You only carry the primary key with you at all times. You keep the backup key in a physically safe space (ie next to your birth certificate).

3. In case the primary key gets lost, you make the backup key your new primary key. You can log in with it everywhere because you already registered it in step 1.

4. You order a new key which will become your new backup key.

5. Go to step 1.
