Then you have to give them your wifi password. Btw, the router password is different than the wifi password.This is a router that is given for free by the provider and does not have this feature!
Yes I’m aware of that thanks.
So there is no software that can help me on my matter?
Let's be honest OP, you sound like you don't have a lot of experience so I wouldn't even bother with what @JT2002TJ is suggesting. If you trust someone enough to share the internet then just give them the wifi password. You would have control of how they 'use the internet' in the actual router settings but, as I stated, you sound very inexperienced so you don't have many choices.To which port of the existing router must I connect the new router to, and what kind of settings must be applied?

OP wants control through software…New wireless router that your neighbor buys, the "internet" Cat 5/6 network port, goes to any open wired output on your ISP's router. This will give his router internet access, and it already has it's own wireless network.
But as @Sheepish-Lord said, you need to adjust some settings. On the new wireless router that he buys (go into that routers menu), you need to make sure that dhcp is turned off (this is what assigns IP address to devices that connect to that new router, this is what a "router" is, the assigning of IP addresses, there can only be one). Then you want to give it an acceptable name and password.
In the end you also need to make sure that the wireless frequencies do not conflict, otherwise you could lose range between both your ISPs wireless network and the new one he buys.
@Sheepish-Lord might be right... Just give him the wireless SSID and password, just make sure your wireless password is different than the ISP's router password.
Can your neighbor see the network? Don’t give him the router’s password, just the network password. Just know that often, the default router user name is “admin” and password is “password”. So you might want to change those.I wish to give internet access to a neighbor. But I don’t won’t to give him the router’s pass (cause then, I will have no control on how he will be using it).
Can I have control on such settings though software?
By network password you are referring to the wifi pass?Can your neighbor see the network? Don’t give him the router’s password, just the network password. Just know that often, the default router user name is “admin” and password is “password”. So you might want to change those.
