Focus Input Field for Login Page and 2FA Component

[Matthew-Grayson]

🐛 Summary

The user input fields are not focused by default. This requires a user to click on the field to start typing. A better practice would be to focus those fields so a user can begin typing without having to use their mouse.

To reproduce

Steps to reproduce the behavior:

1. Navigate to Login page
2. Attempt to type in user name

Expected behavior

When the only thing on a page is a single form or field, that field will be focused so that a user can begin typing without having to click on the field.
