User has questions about default "admin" user removal or disabling
Whether default "admin" user account can be removed or disabled in NFA.
NFA 9.2.x through 9.3.6
1. You should not remove default "admin" user in NFA.
2. For security reasons, you can change the password if needed.
3. Also, you shouldn't disable the account.
The primary reason for this is, NFA internally uses "admin" user for some of its operations. For example, you will not be able to create "Custom Reports" if you remove admin user.
Contact CA Support if you have any more questions regarding this.
