Appwrite supports SMS-based OTP (One-Time Password) authentication to provide secure and reliable user verification. This feature enhances your app's security by adding an extra layer of authentication.
Free testing
You can use the Mock phone numbers feature to test your integrations without incurring any costs.
SMS messages
You'll be charged per SMS sent.
The cost for additional messages is calculated based on two factors:
- The number of messages sent
- The destination country of each message
As part of our commitment to making Appwrite as accessible as possible, we regularly collaborate with telecom providers to negotiate lower SMS rates. Our goal is to keep costs affordable for all users. However, due to the unique pricing structures of each vendor, our rates may fluctuate from time to time.
