Set Focus to Authentication Code Field on 2FA Prompt

This is a simple feature request that could be accomplished with a line of JavaScript. Most websites put the cursor in the Authentication Code field when prompting for a code. With TeslaFi, I have to click in that field before I start typing the code. It would be nice to just be able to start typing without grabbing my mouse. 

This line of JavaScript should do the trick. 

document.getElementById("code").focus();
