Only for my understanding.. The wallet encryption password is the most important one right ? If hackers dont have that, they cannot steal my 5000 syndicate coins right ?
Right, the one which you are using on the local PC and not on your masternode (VPS or else). Make sure to remember it or to save in a protected place, without it your funds will be unrecoverable.
P.S. And the wallet.dat file too (or export the private keys for each of the addresses and also write them down).
