I have a ZTE MF920V LTE MIFI as an Internet source connected to a USB router RT-N56U A1 with the latest OpenWRT 24.10.1, but there is a problem accessing the network because this modem has a password, I don’t know how to register it in the router settings. When I use my smartphone as a USB modem, there are no problems accessing the network. I understand that I can go to the settings of the ZTE MF920V modem itself and remove this password, but this modem is used everywhere, and the password is needed to protect against strangers’ connections. Can you tell me how to set this up?
Show the output of
cat /sys/kernel/debug/usb/devices from the router console.
Thank you for the response. At present, I don’t have access to the ZTE MF920V because it's at another address. Instead, I am using my smartphone as a USB modem. Unfortunately, tonight I reset the Asus RT-N56U and tried to set it up again, but something went wrong. I can't access the internet using my phone, but such a scheme worked just fine yesterday. When I was using the ZTE MF920V, the connection was also fine, only without internet access, I suppose due password required to access to connection for any user

Then you don't need to post yet.
If you have an issue connecting another device like a phone - please start a separate topic.
What is the main difference between using a smartphone as a USB modem and a dedicated LTE modem to access the internet?
On a smartphone the owner must authorize USB Internet tethering by unlocking the screen and clicking the switch for USB tethering in the Settings. There is (intentionally) no way provided for a router to do this through the USB port.
MiFi devices typically don't have any lock on USB tethering by default. I'm not sure what kind of password is involved? Is it a captive portal from the ISP (like at hotels where anyone can connect to the wifi, but attempting to reach the Internet results in being redirected to a login page). This is implemented at the ISP.
I may not have accurately described the situation earlier. What I meant to convey is that the Wi-Fi password is printed on the label attached to the modem. For example, on the recently purchased GL.iNet Flint2 (GL-MT6000), there is a label that includes both the SSID and the Wi-Fi key. How I understand: to access the network, the modem must register the router OpenWrt as a client. Only after that can the router connect to the Internet.
This is called the routed client. It works for MiFi, mobile phone in hotspot mode, hotel WiFi etc-- any situation where you have access to a wifi network but not full control of it.

There is a shortcut to set up the Masquerade option (which is what you want).
Default configuration of OpenWrt.
Log in to webgui and select Network-Wireless. Find the 2 GHz radio (since the MF920 is 2 GHz only) and click Scan. Find the MF920 in the results and click Join This Network. Enter the MF920 wifi password and click Save.
At this point there should be Internet access through the MF920, using a WiFi link.

Great, the system works, the solution turns out to be quite simple for a knowledgeable person, I am ashamed of my stupidity.
I am very grateful for your help, you are my savior.
