Your router's admin web page. What kind of router is it?

...what will you do when those who are currently using your wifi complain that they suddenly can't access the internet?

I have Kasda KW5815 Modem: KW5815 - ADSL2+ Modem Router - Kasda Digital Technology Co.,Ltd

Sounds like a similar issue to this:

Any Network Monitor Tool? - Solved - Windows 10 Forums

Sharing your WiFi password with several parties and then looking for a one button solution to secure it again doesn't make any sense at all.

The only solution to your problem is securing your WiFi connection, but you can't do that if you choose to share the password openly.

Note to others reading this : OP isn't prepared to use router settings, he wants a one click software solution

I can change password from my router but the problem is I have more than 8 devices so I have to re-change password on all devices.

I have 17 MAC address-specified devices accessing my router, and I don't find its an issue.

If you aren't prepared to change the wifi access, then you accept the consequences of poor security. No one-button software solution can protect you against yourself.

Okay.
