You may need a password to access your device.
Or you might need a personal identification number (a “PIN”).
A personal identification number (PIN) is a secret numeric or alphanumeric code that a person uses to authenticate their identity to a system.
If so, you need to carefully record your login password or your PIN into your technology notebook.

Keep a knockin’ but you can’t come in
Little Richard
Keep a knockin’ but you can’t come in
Keep a knockin’ but you can’t come in
Come back tomorrow night and try again
