Got Questions? We Have Answers
What is SMS OTP verification?
SMS OTP (One-Time Password) is a secure way to authenticate users by sending them a single-use code via text message. Dexatel’s solution allows you to verify identities during logins, sign-ups, or transactions in real time, giving both users and your business confidence in the process.
Why should I choose SMS for OTP delivery?
SMS is universal, reliable, and fast. Unlike apps that require internet connections, SMS works on almost every mobile phone worldwide and delivers codes within seconds. It offers global coverage, making it especially valuable in regions with limited connectivity, while also providing a familiar experience for users.
How does it work?
The process is simple: you generate an OTP and send it through Dexatel’s Verify API using your chosen template. The user receives the code instantly, enters it into the application, and the API checks the match. If it’s correct, access is granted.
How long are OTPs valid?
Each OTP is valid only once and expires quickly, usually within one to five minutes, depending on the settings. This short validity period minimizes the chance of misuse and makes the method one of the most secure and trusted ways to authenticate users.
How do I get started?
Getting started is straightforward. You sign up for a Dexatel account, set up and verify a Sender ID, and prepare an OTP template with a placeholder for the code. Integration is possible via API or SDK, allowing businesses to start sending OTPs right away.
How do I track the status of SMS OTPs?
Dexatel’s platform includes real-time monitoring and analytics that let you see whether each OTP was delivered successfully, giving you full visibility into the verification process and allowing you to optimize for reliability.
