Use User's Password As Enable Password
(2020-12-17)
Problem
I want to use my username password as the enable password in ssh sessions
Solution
The ASDM will use the password from your Username, while when logging in to the console it will use the enable password when you enter exec mode (when you type "enable"). If you want to use the same password for the enable password as you do for the ASDM for both SSH and console you can enter these two commands:
aaa authentication enable console LOCAL
aaa authentication serial console LOCAL
You should now be able to use your username password as the enable password.
