A discovery by a KCB customer revealed that the bank's mobile app appears to only authenticate the last four digits of a six-digit PIN, a revelation confirmed by KCB and slated for a future update.

• The KCB app allows users to set six-digit PINs but allegedly only verifies the final four digits for login.
• Key organizations involved: KCB and a concerned customer who shared the finding on X.
• KCB stated this is a limitation of the current PIN entry interface that will be resolved in a future app update, though no timeline was provided.
