I might be misunderstanding. Are you able to log into the Steam Client on your desktop, where you download games and all that or are you having issues logging into that? Is the game itself where the login error happens?
Regardless, I would try closing out of Steam completely, logging into Steam on their website. Change your password and re-log into Steam on the website. After that, get your phone, download the Steam App and login on the phone. On the app you will be able to setup 2-step verification (Steam Guard,) which is where you login normally on your PC, then it sends a code to your phone that you must type in within 30-45 seconds (don't know the exact time, just seems around that area.) After you enter the code in, it logs you in.
So a quick recap. Close out of Steam on the desktop completely; click the little ^ on the bottom right of your screen, find steam, right click and hit close/quit/exit. Then log into Steam on their website. Change your password on it, then login again. After that, download Steam App on mobile and login. If you are able to login, while on the app, setup Steam Guard. After you go through all of that. Now attempt to login on your desktop through the Steam Client. If you are able to login, you are good to go. If not, reply back and we'll try to figure it out again.
