How to center a component in Material UI and make it responsive?

I don't quite understand the Material UI grid system. If I want to use a form component for login, what is the easiest way to center it on the screen on all devices (mobile and desktop)?

Since you are going to use this on a login page. Here is a code I used in a Login page using Material UI

Material UI v5

<Grid
  container
  spacing={0}
  direction="column"
  alignItems="center"
  justifyContent="center"
  sx={{ minHeight: '100vh' }}
>
  <Grid item xs={3}>
    <LoginForm />
  </Grid>
</Grid>

Material UI v4 and below

<Grid
  container
  spacing={0}
  direction="column"
  alignItems="center"
  justify="center"
  style={{ minHeight: '100vh' }}
>
  <Grid item xs={3}>
    <LoginForm />
  </Grid>
</Grid>

this will make this login form at the center of the screen.

But still, IE doesn't support the Material-UI Grid and you will see some misplaced content in IE.

As pointed by @max, another option is,

<Grid container justifyContent="center">
  <Your centered component/>
</Grid>

Please note that versions Material UI v4 and below should use justify="center" instead.

However, using a Grid container without a Grid item is an undocumented behavior.

In addition to that, another new and better approach will be using the Box component.

<Box
  display="flex"
  justifyContent="center"
  alignItems="center"
  minHeight="100vh"
>
  <YourComponent/>
</Box>
