Manage Dahua passwords and users
A recorder becomes difficult to manage once everyone uses the same admin account or nobody knows who is managing the recovery.
Setting or condition
Distinguish between owner, administrator, viewer, and temporary user. Also check which old accounts or devices still have access via app or browser.
Making a conscious choice
Use unique accounts with minimal necessary permissions and keep recovery information securely with the owner. Do not share administrator passwords via group apps or notes next to the recorder.
What you check afterwards
Sign in with a viewer account and confirm that settings cannot be changed. Remove a test user and verify that access disappears on all routes.
Frequently asked questions
Can a viewer delete images?
That depends on the rights; only grant that authority where it is truly necessary.
Why not a shared admin password?
You then cannot trace or revoke who has had access.
