Enabling SSH to your Cisco ASA Firewall

Its important to mention this will work on either inside or outside interfaces, but you should preferably only have this available to the inside, unless you're able to identify a very small number of IPs that are permitted externally. Check here to see Known SSH Vulnerabilities. Step 1 Creating an enable password 
DBTN-ASA(config)# enable password Password1
DBTN-ASA(config)# username dbtn password Password1 privilege 15
Step 2 Defining which IPs are permitted 
DBTN-ASA(config)# ssh 10.10.83.0 255.255.255.0 inside
Step 3 Define a domain-name 
DBTN-ASA(config)# domain-name dontblamethenetwork.com
Step 4 Generate your rsa key 
DBTN-ASA(config)# crypto key generate rsa modulus 2048
Step 5 Tie your authentication method to local logins LOCAL is a predefined keyword to look at device level logins 
DBTN-ASA(config)# aaa authentication ssh console LOCAL
Thats it! SSH in and you're in business!
