1.3 Security Tips
- When creating a Nxt account, if you design your own passphrase, ONLY USE a high security passphrase (50+ characters, truly random, including upper case and lower case letters, numbers and symbols). Your NXT WILL eventually be stolen if you don't use a secure passphrase! Here's how to choose a strong password.
- Nxt's peer-to-peer communications port is 7874 (tcp). This port is the only port that needs to be open to run Nxt.
- Nxt also uses port 7876 for its web client interface. You should close port 7876 on your firewall to prevent other people from accessing your server.
