# TwilioAuth SDK Quickstart Tutorials

> \[!WARNING]
>
> The TwilioAuth SDK has been deprecated. This means that while we will continue to provide maintenance support for existing customers and their usage, we discourage new customers and new usage, as we may shut it down entirely in the future. We strongly recommend using the [Verify Push SDK](/docs/verify/push) instead, which currently supports the Push channel, and will be enhanced to support the TOTP channel in the future.

## What is the TwilioAuth SDK

The TwilioAuth SDK is a native library for both Apple iOS and Google Android that allows you to implement [push authentication](/docs/verify) and [TOTP](/docs/verify) capabilities in your own mobile application.
