Hello, any news?

Hi,
Question ican be divided in 3 subsquestions below:
1) I enabled ssh server in Ubuntu, and works fine, even in desktop. But had to leave firewall open - not sure which port was going to be used and shows it was port 11895! Why not using port 22,vwhich is a best practice?
2) Because of what was described above, is it recommended to use VNC instead?
3) Authentication: Based on user and keys? Seems to me yes, but could not find evidence
