To enable it, go to ‘System Preferences’. Under ‘Internet & Networking’ there is a ‘Sharing’ icon. Run that. In the list that appears, check the ‘Remote Login’ option. In OS X Yosemite and up, there is no longer an 'Internet & Networking' menu; it was moved to Accounts. The Sharing menu now has its own icon on the main System Preferences menu. (thx @AstroCB)

This starts the SSH daemon immediately and you can remotely login using your username. The ‘Sharing’ window shows at the bottom the name and IP address to use. You can also find this out using ‘whoami’ and ‘ifconfig’ from the Terminal application.`
