You may run the following commands if you wish to manage your keys on a local vinced node or validator.
Viewing keys: vinced keys list to view all Keys in your keyring
Adding or recovering keys: vinced keys add <keyname> --recover --keyring-backend=file
You can import or add a new key with or without an existing seed phrase. If you wish to recover keys, then use the command --recover. This uses the file keyring backend, prompting you to enter a password and encrypting your keys in the keyring folder.
