Why Do You Forget Your Own Password?

Imagine your brain is a giant library. When you type a password like 1234, your brain has to find that specific card quickly. But sometimes, the librarian gets confused because other numbers or similar cards are nearby.

You might know the answer right before lunch but forget it when hungry. This is because context helps us remember. If you usually type passwords on a computer keyboard, holding your phone changes the 'library' slightly, making it harder to find the exact spot. Also, if you change your password often, the new one blocks the old one. It is like trying to hear one voice in a noisy room; the noise drowns out what you need!
