Hello dear developers
[ As a security suggestion ]
I have been using OpenWrt for about a few months. And during this time I came to the conclusion that OpenWrt can add ( Delay after incorrect 15 incorrect login in the login page ) function in future updates.
Please add this feature in the next updates.
Even the main operating system of the router itself has the possibility to cut off the user access password for 600 seconds after 15 wrong password.
File your feature request here:

Or restrict access from LAN with firewall.
And use VPN or SSH for tunneling.
