access codes
Digital entry credentials
Access codes are sequences of numbers, letters, or symbols that grant entry to secured systems, spaces, or information.
They function like passwords but often apply specifically to physical entry points like buildings and gates, or to one-time authentication such as verification codes sent to your phone.
Enter your access code to unlock the door.
The term emphasizes authorization—having the right code means having permission to access something otherwise restricted.
