Are passwordless SSH logins more secure?

My friend and I recently had a 'thoughtful' discussion on whether SSH authentication is more secure than authentication using passwords. He always connects to servers with passwords but I prefer to log into our system without having to enter a password every single time. I know he's scared about that but what should I tell him? Personally, I think passwords are terrible because they could be brute-forced or captured by a key logger. Does everyone think password SSH logins are more secure?

Accessing a system without any type of authentication is never a good idea.  These types of sites could have software that you have access to for downloading and then your system has become a zombie.  Always use a password and use one with the following criteria:

Uppercase
Lowercase
Numbers
Special characters
And at least 15 characters long
And change it at a minimum of 90 days

Don’t make it easy for a hacker to gain access to your things even thou you have nothing in the storage area.  Once a hacker gains access, they can go about the site and target other accounts, you just left the door ajar.

Read the news and see how companies are losing other peoples personal information.  The customer now has to deal with identity theft and I am sure that is something that you do not want to have to deal with.  It takes a long time to repair and will cost you sometimes.

There is nothing that is fool-proof, just don’t make it easy for the hacker.

    I presume you are making SSH connections via encryption key pairs? It can certainly be argued that this is a more secure approach. However, once a criminal hacker compromises your system, all bets are off for any type of login mechanism.
