Any time you change the yubikey you use you have to delete (`gpg --delete-key`), refetch the key (`gpg --card-edit fetch`), and set the trust to full (`gpg --edit-key 01B157D574FEDBB2 and then put ultimate trust in the key`) ~~Any time you change the yubikey you use you have to delete (`gpg --delete-key`), refetch the key (`gpg --card-edit fetch`), and set the trust to full (`gpg --edit-key 01B157D574FEDBB2 and then put ultimate trust in the key`).~~
[A direct way](https://github.com/drduh/YubiKey-Guide?tab=readme-ov-file#using-multiple-yubikeys) is:

gpg-connect-agent "scd serialno" "learn --force" /bye
```
Finally, in the NIX environment I use for my mac all the GPG tools live in /Users/olaf/.nix-profile/bin. Hence, for mailmate I need to set:
```
defaults write com.freron.MailMate environmentVariables -array '{"enabled" = :true; "name" = "MM_GPG"; "value" = "/Users/olaf/.nix-profile/bin/gpg";}'
```
