Getting the knox lock out

Hey I used to be a student at pala (residential batch) a few years back and I discovered my tab from then. I remember ppl used to spam the shit out of the apps and it would crash but rn the apps take too much goddamn time to load it's just funny. Samsung one, and idk the password to it, can y'all help me out? Dms is fine ig

Help would be appreciated 🙏🏼
