VaultKeys are account numbers you can share with companies, vendors, and merchants so they can directly debit or credit funds from your account.
VaultKeys are like traditional Account Numbers. You can use these to grant transaction access to your Vaults for purchases and credits.
YOU are in full control of your Vaultkeys. You can turn them off at any time which stops access to that vault immediately.
You can have a maximum of 10 VaultKeys
