What is Silent Authentication?
Most authentication still relies on SMS one-time passwords. The user requests a code, waits for it, types it in, and hopes it hasn’t expired. It adds friction, drops conversions, and can be intercepted.
Silent Authentication removes that process entirely. Instead of sending a code, tyntec checks the mobile network directly — in the background, in under two seconds — and confirms that the person using the app is the owner of the mobile number they claim to be.
The user doesn’t see a code. They don’t need to do anything. The app just works.
In plain terms: “Is the person using this app right now the same person who owns this phone number?” — answered automatically, without asking the user.
How it works — for non-technical readers
When a user opens your app and starts a login flow, here is what happens:
- Step 1. The user’s device is on mobile data. Your app sends their phone number to tyntec.
- Step 2. tyntec asks the mobile network: “Is this phone number active on the device that just made this request?”
- Step 3. The network responds instantly. If the number matches, tyntec confirms the identity.
- Step 4. Your app receives a confirmation token. The user is logged in. No code was ever sent.
That’s it. No SMS. No waiting. No user action required.
