Mobile authentication

Authentication redesigned

Kie.la lets you sign-in to websites and mobile applications from your phone or tablet with a simple one-time passcode — no email address, no passwords to remember, no SMS codes to wait for.

Download on Google Play See how it works

One-time passcode

  1. 1 Open the Kie.la app on your phone
  2. 2 Copy the passcode shown in the app
  3. 3 Enter it on the website with your PIN

You authenticate yourself — it's not the website authenticating you.

You are in control of the authentication.

How it works

When a website uses Kie.la, sign-in takes a few seconds. Your phone holds the keys — the website never sees your password or PIN code.

Step 0

Open the app. Sign in, once

Enter a nickname, your name, email and mobile number and PIN — email and mobile are verified.

Step 1

Open the app

Launch Kie.la on your Android device. Type your PIN. You are in, secured.

Step 2

Get a one-time passcode

The app displays a 6-character code: two letters followed by four digits.

Step 3

Sign in on a website

Enter the passcode and your 4-digit PIN on the site. Confirm on your phone when asked to.

Step 4

You're in

The profile is shared with the web application. Only what you decide.

Why Kie.la

Built for people who use the web every day and for teams who want strong authentication without friction.

No passwords on the web

Your PIN stays on your device. Websites verify a one-time code instead of storing credentials.

Phone-first

Authentication is initiated from the device you already trust — your mobile phone.

You stay in control

Approve sign-in requests on your phone. Revoke access anytime from the app.

For developers

Integrate Kie.la sign-in into your website or mobile app with a reference test site, a sample Android app, and documentation. After sign-in, your backend receives a verified session and the profile fields you choose to share.

Test website

Public home page, header sign-in, and a private area with profile field — a minimal web integration.

Open test site

Developer console

Register applications, configure profile fields, and download integration settings for your project.
