+You can generate authentication keys and use it with ssh to login. First run the below command if you don't have any (it won't overwrite if you already have one):
+
+```
+ssh-keygen
+```
+
+Then copy your public key to remote server with this:
+```
+ssh-copy-id name@host
+```
+
+From now on, you should be able to login with `ssh name@host` without having to enter your password.
