Let me log in with a password instead of with a text code

I have other team members who need to log-in and check on projects or estimate projects. It's not convenient nor obvious to log them in with my number, then have me send them the 6 digit code. Every time I add a member, I need to repeat that process.

Sometimes it's not convenient to log in with the text code. I may be out of reception.

I also log in from my computer, and would prefer to use a password to log in from there.
