Deliver SMS verification codes across Portugal to protect customer sign-ups, authentication, payments, and account recovery.


SMS multi-factor authentication requires users to complete an additional mobile verification step before accessing an account or approving a sensitive action. A one-time SMS authentication code is generated for the request and expires after a limited period. Teliqon allows businesses to integrate OTP SMS for customers in Portugal through one API. It can support registrations, secure logins, payment confirmation, account recovery, and two-factor authentication SMS workflows across websites, applications, and customer platforms.
Teliqon’s OTP SMS API connects verification to registration, account access, payment approval, and recovery workflows in Portugal.
A one-time code arrives in the customer’s SMS inbox, providing direct access to verification during login, registration, or payment.
The SMS authentication code follows a familiar enter-the-code process for registrations, account logins, payments, and recovery.

With SMS multi-factor authentication, a temporary code is sent to the customer's registered mobile number when identity confirmation is required. The customer enters it to complete a login, registration, transaction, or recovery request. The code becomes invalid after use or expiration, adding a separate check beyond the account password. This gives customers in Portugal a familiar way to prove control of the number connected to the account.
