Abstract: An operation method with fingerprint recognition, an apparatus, and a mobile terminal relate to the field of communications technologies, where the method includes obtaining a fingerprint input by a user's finger at a preset position on a touchscreen of the mobile terminal, displaying at least one shortcut when the fingerprint matches a preset fingerprint and a duration of the finger at the preset position on the touchscreen exceeds a predetermined duration, detecting a sliding operation input by the finger using the preset position as a start position, determining a first shortcut from the at least one shortcut according to a direction of the sliding operation and running the first shortcut. Thereby reducing operation duration, and improving operation efficiency.
