This repository contains a custom-built OTP (One Time Password) Input Field and integration with Google's SMS Retriever API for OTP fetch and populate functionality, developed using Jetpack Compose. This component is designed to cater to modern Android applications requiring OTP verification, offering a blend of customization and ease of use.

This is not a library. This is a demo project to experiment and try out a functionality.

• Integration with Google's SMS Retriever API to auto verify OTP and populate.
• OTP input field can be set up for any length of OTP.
• Supports automatic filling of the OTP, a convenient feature for OTPs received from servers or other sources.
• Offers options to show a cursor, and control its blinking, enhancing the user experience.

Right now Jetpack Compose does not have good support for Autofill. There have been some temporary solutions like ExplicitAutofillTypesDemo.kt. Google is working to add support and we may have it in the future. Autofill will benefit from filling fields like name, emails, credit card numbers, and OTPs from IME directly.

Open issues related to Compose Autofill:

• https://issuetracker.google.com/issues/265911809
• https://issuetracker.google.com/issues/176949051

I did some experiments with the temporary solution and looks like this. But it does not work smoothly and has many issues:
