Allow for Multi User Teams

I have multiple team members at my company who need access to my account. They include my foreman, my superintendent, my admin, my estimator, and more.

Right now, I need to have them log in with my number, I get a 6-digit code texted, and I have to share it with them. It's a little clunky. If they get logged out, we need to repeat this.

Give me a way to invite members to my account. This would let them log-in without bothering me.
