My question cause by my potention misunderstanding of how network works. Situation: I have my wallet number (only number) and its password. Can I (and how) transfer amount from this wallet to any other address? Or I must provide JSON wallet/key phrase/etc.?
In a few words no. To create a transaction sending your funds to someone else you have to cryptographically sign the transaction data with your private key, which is inside the JSON wallet file encrypted with your password.
