Not the parent, but I write recovery codes down and store in a safe at my home.
The difference compared to a password is that these recovery codes are single use, used only in exceptional cases and physically airgapped. On the other hand my password is multi use, is used daily by me and in the event of a breach will be exposed to the attacker.
I will know if someone steals my recovery codes. I'll have no idea if someone gains knowledge of my password though.
Do you have recovery code printed out? Do you carry them with you? If you do then what's the difference between this and a password?
