Can I make a login menu that works with Apple’s built-in password manager?

Questions

Hi everyone!
I’m making a little app for a friend at the moment, and I need to make a login menu so people can use it. I know (sort of) how to make a login menu, but I’m not sure it will be compatible with Apple’s “Keychain” feature. Any ideas?

You could pop up a web browser showing a login/register page, you’d have to code that page though.

@DJMoffinz Don’t know if anything like this would help. Wrote this a long time ago. After going to a url, tap Done in the upper right to exit back to the menu code. Maybe this would give you an idea of something to try or maybe it won’t be anything useful at all.

    table.insert(buttonTab,button(350,500,100,50,"Screen 2",menu,screen2))
    table.insert(buttonTab,button(350,400,100,50,"Screen 3",menu,screen3))
