If you still have access to your phone / wallet:
You can cancel the recovery from the Argent app. Go to the "Security" tab and tap the message about the recovery. You will see the option to cancel it.
If you have Guardians in addition to Argent Guard, they will need to approve the cancellation.
Friend or family Guardians can approve the cancellation in their app.
If you have a hardware wallet, you can connect it at www.argent.xyz/hardware-wallet. Search for your Argent wallet name / ENS, and then approve the cancellation.
If your phone has been stolen and the thief has requested a recovery
- Make sure that your Guardian(s) do NOT approve the request.
- Lock your wallet with a Guardian
- Recover your wallet on your new phone
