HI and thank you for your replies
By disabling the account, I didnt mean deleting the profil.
For example, on my NAS, I created an "admin user" called XXXXX, with all the admin's right but the login name is not "admin".
The "admin profil" is still activated through this user.
In addition, on my NAS, the "admin user" is only working on the LAN. The access is not granted outside my LAN.
I only wanted to know if the same thing can be done on the camera but I understand that a NAS system has more functions than a camera.
For the password, I always try to put strong one with Capital letters, Digit, not under 8 characters, ...
