For some very basic login information, you can use the last command. For instance:

root@web-02:~# last root
root     pts/0   Wed Dec  2 10:49   still logged in   
root     pts/0   Wed Dec  2 10:49 - 10:49  (00:00)

wtmp begins Tue Dec  1 17:22:59 2015

Notice the history only goes back so far as the logs get rotated. You can also look at older logs by specifying the file:

root@web-02:~# last -f /var/log/wtmp.1
root     pts/0   Wed Nov 18 11:21 - 11:23  (00:02)    
root     pts/0   Fri Nov 13 10:42 - 10:42  (00:00)    

wtmp.1 begins Fri Nov 13 10:42:21 2015

For even more information, you can inspect /var/log/auth.log It will also contain information like failed login attempts.
