Is it safe to have money on Robinhood?

Could you please elaborate on the safety aspect of keeping funds on Robinhood? I've been hearing some mixed reviews, and I'm a bit concerned about the security measures taken by the platform. How does Robinhood protect its users' money from potential hacks or fraudulent activities? Also, are there any specific instances in the past where users have lost money due to security breaches on Robinhood? I'd appreciate it if you could provide some clarity on this matter.
