As cloud computing grows, safety becomes increasingly crucial. User registration is a cloud security weakness because weak or stolen passwords let hackers entry. This research examines how to make cloud computing safer using better passwords and MFA. Bcrypt, Argon2, and hybrid encryption techniques can protect user data from unauthorised access. MFA combines a password, a mobile device, and biometric data to improve security. This reduces the likelihood of unauthorised logins. How effectively these security solutions perform, scale, and pose difficulties in cloud contexts are also examined in the research. The proposed solutions reduce password hacks and safeguard cloud data privacy and security. Fixing these issues would make cloud systems less susceptible to attackers, improving the digital environment.
