What is OTP verification?
Dexatel’s OTP verification service sends a one-time code to a user’s phone via a messaging channel like SMS or WhatsApp. They enter it to prove it’s really them. It’s faster and safer than a password alone.
What will you use OTP for?
Keep fake users out without slowing real customers down. Send a one-time passcode to check they have access to the phone number they provide.
- Valid phone number
- Real customers
- Fewer fake accounts
Preguntas frecuentes
Why should I use OTP verification?
Passwords aren’t perfect, and there are some instances where you need to double-check you are interacting with the right person.
OTP gives you a practical way to add stronger authentication. And it’s convenient for your users. No extra app and no need to carry another device.
What happens if an OTP code doesn’t arrive?
That’s up to you. Choose how long to wait and which channel to try next, so one delivery problem does not cause a problem for your customer’s journey. Still a problem? Give us a call.
Do I need a developer to use the Dexatel OTP API?
You will need some technical support to connect the OTP verification API to your website or app. But Dexatel gives you the documentation and guidance to configure and test everything as easily as possible.
How long should an OTP code remain valid?
ong enough for a real person to use it, but not long enough to create unnecessary risk. The right window depends on what you are protecting; the team can help you decide based on your use case.
