One Time Password (OTP) authentication adds an extra layer of security to your guest WiFi while ensuring only valid phone numbers access your network. By requiring SMS verification, you prevent fake signups, collect verified contact information, and enable SMS marketing campaigns to re-engage customers.
This guide walks you through enabling OTP login on your Spotipo guest WiFi. The setup requires an SMS gateway integration and takes approximately 10 minutes to configure. Once enabled, guests must verify their phone number with a text message code before accessing your WiFi.
What you'll accomplish:
Configure an SMS gateway for OTP delivery (Twilio, Messagebird, or other supported gateways)
Enable phone number collection on your splash page
Activate OTP verification for guest authentication
Test the OTP flow to ensure proper functionality
What you'll need:
Active Spotipo account with a configured site
SMS gateway account (Twilio, Messagebird, Firetext, or ECall)
SMS credits or subscription for sending verification codes
Business benefits: OTP authentication reduces spam signups by 90%+, ensures marketing compliance with verified contacts, and provides a friction-balanced login method, secure enough to prevent abuse, but fast enough not to frustrate legitimate guests.

Clear error messaging: Help users troubleshoot if codes don't arrive
International guests: Ensure your SMS gateway supports international numbers if needed
Backup authentication: Consider offering email login as an alternative for guests without mobile service
Common OTP setup issues:
Codes not arriving: Verify your SMS gateway is properly configured with valid credentials and sufficient credits
Wrong country code: Set the default country code in phone field settings to match your location
Verification timing out: Check your SMS gateway delivery speed—some gateways are faster than others
International numbers failing: Confirm your SMS gateway plan supports international SMS delivery

Twilio: Most reliable, global coverage, higher cost per SMS
Messagebird: Good balance of price and reliability
Firetext: UK-focused, competitive pricing
ECall: Budget option for specific regions
