SSH Login - Bypass public Key check (temp disable passwordless login)

I've search until I'm 'blue in the fingers'..
There is a lot of info on generating a key pair, uploading, configuring hosts etc.. But...

Here is my situation.
1) I have both id_dsa and id_rsa keys. Use one for GitHub other for Launchapd.
2) I can Login to them just fine, having copied my pub_key there.
3) the Problem is I also have a 'Reseller' (shared) web server at HostGator and I do not have root access on it.
4) Therefore, I can Not scp, or ssh-copy-id my Public Key to the Server's /.ssh/Autorize-whatever.
5) When I try and SSH into one of my Domains at HG, I am being Rejected, I assume because My KEY Does NOT match my 'cpanel' login user name (cpanel user is the same user, used for HG SSH login ('jailshell'))
6) If I temporarily re-name my ~/$HOME/.ssh directory to dot.ssh I can Login to my domain via SSH just fine.
7) the Question: How do I Bypass Key uses?
ie, How do I login as a plain user from console as if I did not have a private/public key?
8) There Has to be a way, because not all server have Key login or what if I just want to login to a clients server, just once to take a look around for them... I would Not want to go through the whole key generation, copy (upload) key routine... Right? !

9) This 'server' is mine, has been for 2 years and will remain 'mine' for the foreseeable future, so having a key would work and I would create a ~/.ssh/config file defining what key / login / server , but Again, I can Not copy the key to the 'shared' server.

10) # ssh -(NoKey_option_or_something) -p xxxx ?????? some command line option to bypass key check and Just use the information provided in this login line, for this session. ????

Thank You in advance,

Either pass the "PubkeyAuthentication no" option using "-o " on the command line or for a more permanent solution try something like this in your ~/.ssh/config:
Host whatever_provider_name
HostName whatever_machine_IPv4_address
Port 2222
User whatever_user_name
PasswordAuthentication yes
PreferredAuthentications password
PubkeyAuthentication no
*Note this isn't the way SSH should be used so please re-check the providers procedures to get pubkey auth enabled because I'm pretty sure they offer it.
