Hello,

You can use "-i" switch when connecting to the host to specify the identity 
file (containing the private key). 

Also u can specify identity file on per host basis in the configuration file 
located at "/etc/ssh/ssh_config". Or use a per user configuration file using 
the "-F" switch. 

also as I understand ssh uses 2 factor authentication it uses RSA or DSA keys 
plus the provided username and password provided proper access control on the 
ssh key files usually located "~/.ssh/Id_rsa" and "~/.ssh/id_dsa". 

Hope this helped.
