Salvation is by faith alone.
We can’t earn it or keep it by works.
Where Catholics err is that they assume that just because we believe that works play no role in procuring salvation, that they are unimportant and nothing could be further from the truth.
Getting saved is the beginning of a walk with Christ which is sanctification and the goal is to become more and more Christlike as we progress. That includes obedience to God’s commands. But it doesn’t keep us saved. It keeps us growing.
And lack of works does not mean lack of, or loss of salvation. It can result, however, in the Lord’s discipline to correct us.
Contrary to Catholic thinking, when God saves us, He does not abandon us to fend for ourselves and then zap us when we screw up. He is active in the life of the believer, always. Even when that believer is not in a place of full fellowship with God because of sin.

No, but you can loose it through sin. Catholics, contrary to Protestant allegations, do not believe that we earn our salvation through works. Although we do not believe in sola Scriptura or sola fide, we do believe in sola gratia.

You have a major misunderstanding of Catholic teaching. Although we can abandon him, God never abandons us. He is constantly sending us his grace to avoid sin or to repent from our sins. Even when we are separated from him by our choice when we commit a mortal sin, he is still sending us his grace to repent. And when we do, and approach him in confession, forgiveness is ours just for the asking. We do not earn it by anything we do. If you are going to critique Catholic teaching, I would ask you to do so on what we actually believe, and not on a Protestant caricature of it.
