Update
The regular key pair need not even be an activated XRPL account. It’s used only for signing purpose, so having a valid secret key is enough. Being activated or not activated on XRP Ledger doesn’t even matter.
Final tip: A regular key can sign all the transactions of the master account, except AccountSet transaction which disables the master key. Only master account can disable the master key. But a regular key can revoke the disabled master key and restore its ability to sign transactions.
