means To make something safe, fastened, or guaranteed against loss, attack, or escape — or to successfully obtain something you were after.

from Straight from Latin securus, a tidy compound of se- 'without' and cura 'care' — literally 'free from worry.' That carefree root also gives us 'sure' (a worn-down cousin that came through French) and lurks inside 'curate' and 'curious' on the cura side. So to be secure was, at heart, to have nothing to fret about — a meaning that drifted from peace of mind toward locks, passwords, and bolted doors.
