USSD & shortcodes · Secure authentication
Secure USSD services with PINs, OTPs and session control.
When a USSD service handles money or personal information, security matters. We build in PIN protection, one-time passwords and careful session handling, so only the right person can access an account.
What’s included
What Secure authentication covers
- 01
PIN protection
Users set and enter a PIN before they can see sensitive information or transact.
- 02
PIN reset
A safe way for users to reset a forgotten PIN.
- 03
One-time passwords
OTPs sent by SMS to confirm registrations and important changes.
- 04
Lockouts
Accounts locked after repeated wrong attempts to stop guessing.
- 05
Session control
Sessions that can’t be resumed by someone else on another phone.
- 06

How it works
Three steps, no jargon.

Assess
We identify what information and actions in your service need protecting.
- 2
Build
We add PINs, OTPs and controls without making the service hard to use.
- 3
Test
We test the security flows, including what happens when things go wrong.

Are PINs stored safely?
Yes. PINs are stored in a protected, hashed form, never as plain text, so even our team can’t read them.
Will security make the service harder to use?
We keep the extra steps to the moments that need them, like viewing a balance or making a payment, so everyday use stays quick.
Does this help with the Data Protection Act?
Good security is part of protecting personal data under Kenya’s Data Protection Act. We’ll build the technical controls; your organisation remains responsible for its wider data policies.
