 ## Set attributes
 
-Use previously set values:
+Set a public identifier for the gpg subsystem:
+```console
+export GPG_LOGIN_ATTR="My Cool YubiKey - 2025"
+```
+> [!IMPORTANT]
+> Anyone with access to the yubikey can see this attribute, even without authentication. It is recommended not to include personally identifiable information in this field to prevent a bad actor from associating a lost yubikey with its owner.
+
+Update the login attribute:
 
 ```console
 gpg --command-fd=0 --pinentry-mode=loopback --edit-card <<EOF
 admin
 login
-$IDENTITY
+$GPG_LOGIN_ATTR
 $ADMIN_PIN
 quit
 EOF
 ```
