• Authentication - A password acts like a secret handshake, confirming your identity when you access a device.
• Access – A password grants individual users access to their device, allowing them to use it.
• Security - A password keeps individual files, data and information safe from people who shouldn't see them or who are not authorized to access them.

Thus passwords are essential to safeguard sensitive personal information like pictures, games, messages, chats etc., from unauthorized access.

 It's like a special lock that only an individual user can open to help keep their things safe!
