A communication apparatus includes a reception unit that receives a Bluetooth® beacon signal transmitted from a printing apparatus, an identification unit that identifies a reception field intensity of the beacon signal, a display unit that displays a reception screen for receiving a transmission instruction in a case where the identified reception field intensity is less than a first threshold and greater than or equal to a second threshold that is smaller than the first threshold, and a transmission unit that transmits, to the printing apparatus, an authentication request enabling a user to log into the printing apparatus in response to receipt of the transmission instruction.
