Mobile money reaches 23.2 million adults and banks reach 14.8 million, on the 2024 FinAccess household survey. The gap in mobile money use between women and men narrowed to 1.8 percent, from 5.2 percent in 2021. Internal fraud was the leading label where money was lost in a savings cooperative (75.1 percent) or a pension scheme (66.1 percent). Accidental sending was the prevalent way mobile money was lost, at 70 percent.
In the quarter to December 2025 the incident team said users were reached by calls, texts and messages impersonating an institution, an employer, a delivery service or a government agency, with urgency around travel, promotions and bonuses. Phishing messages copied a real brand or a payment platform to harvest a mobile banking login.
An email or a text that looks as if it comes from the bank asks for a PIN or a password, and card skimmers copy the magnetic strip. The Authority's Kiswahili guide calls identity theft wizi wa utambulisho. The usual method is kuvua: a baruapepe, an email, that is laghai and asks for a name, a PIN, a national identity number or a card number. The same guide names a work-from-home fee, a foreign lottery, a forged cheque, an advance-fee loan and an investment promising a high return with no risk. SIM swaps were still among complaints in July to September 2026, some of them used to reach a financial account.
