+# Recovery Notes (age + sops)
+
+## If you lose the age identity
+You cannot decrypt existing secrets without the age private key stored in:
+
+- `~/.config/sops/age/keys.txt`
+
+Keep an offline recovery copy (USB/QR/printed).
+
+## Rotating recipients
+Add additional recipients to `.sops.yaml` and re-encrypt:
+
+- `sops updatekeys -y secrets/*.enc.yaml`
