Default SSH username doesn't match $USER value in macOS
Note: I managed to get this working, now I'm trying to figure out why there's a discrepancy.
I recently enabled remote access on my laptop running macOS High Sierra. However, I initially had trouble ssh-ing in. When I ran ssh localhost it would prompt me for a password which it always rejected. When I ran ssh ${USER}@localhost my SSH keys kicked in and I logged in immediately.
After turning up the verbosity, I noticed that ssh localhost was attempting to authenticate as firstname.lastname, but my user account and $USER variable are firstnamelastname (without a dot). This explains why ssh ${USER}@localhost worked and the other didn't.
So what gives? Why is ssh trying to authenticate with something other than $USER? Where is it getting the dotted form from?

If ssh localhost is using a different username from the one in $USER there might be a line overriding the User in your ssh configuration file.
Check in ~/.ssh/config and /etc/ssh/ssh_config
You can also try to add the following line in your ~/.ssh/config (create the file if it doesn't exists):
User firstnamelastname
Then, restart ssh:
sudo launchctl unload /System/Library/LaunchDaemons/ssh.plist
sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist
and check again your ssh default user name with verbose mode:
ssh -v localhost
You should see a line like this:
debug1: Authenticating to localhost:22 as 'firstnamelastname'
(That is, the one you defined in your ~/.ssh/config)
