set ssh authentication to LOCAL.

or use default username (pix?) with default password.

I was able to SSH using pix and the user access mode password. How do I change the default username PIX?

Thanks

Enter this command aaa new-model

The aaa new-model command causes the local username and password on the router to be used in the absence of other AAA statements.

Or enter login local on the config of the line vty 0 15

Try adding:

aaa authentication ssh console LOCAL

into your config. This assumes you are not using some exterior form of authentication.
