Sign

A "sign in" is the process of verifying your identity to access a secure system or service, like a website or app. It usually involves entering a username and password, ensuring only authorized users can view sensitive information or use certain features. Think of it as unlocking a door with a key—it's a way to confirm that you are who you say you are. Signing in helps protect your personal data and ensures that your account remains private and secure from unauthorized access.
