password protect one single page??

Requirements for page:
1) is published
2) NOT shown in menu
3) require ALL users to type a password to see the page -- ideally going to the page throws a popup requesting the password, typing password into the popup shows the page, if necessary an ID is okay too

I was thinking of:

1) can I use .htaccess or the nginx equivalent?? Or does modxcloud make this not possible to do??

2) can I use a template variable and check the person typed in the right value??

I don't want to use the Login extra if possible, we need something simpler for extremely NON-technical people, some of whom barely know how to use a browser.

Thank you, Tom

PageLocker looks like what you need

https://modx.com/extras/package/pagelocker

Doing it by htaccess is ok too

I don't think finally its very sensible to go around login, but what is your real need? If its just a login box that's not complicated.

Not shown in menus is a value for the resource (page), its a checkbox/flag that can be ticked.

I already found PageLocker, the fewer plugins to worry about maintenance or obsolescence, the better.

The fewer the pages involved the better.

I know about not shown in menus, I've used MODx since 2012.

Thank you, Tom

Ok then htaccess is the way to go I guess, maybe use a custom script...

I don't think pagelocker has been updated for over 5 years so there's not much maintenance to worry about there, it works well though.

Password Protect Your Web Pages and Files With .htaccess and i have tried this one on my web.
