Arguments on remembering the various yubikey pins

Apologies, if this has been asked before.

Just wondering what most people are using to remember the variety of pins you have with the yubikey. oath pin, fido2 pin, piv pin/puk etc. What is your argument for doing so?

1. good old brain
2. pen and paper
3. offline password manager - keepassxc etc
4. other pass managers - bitwarden etc

Any other?
