RCognito

RCognito is an R package designed to simplify interaction with Amazon Cognito services through a user-friendly API wrapper. Seamlessly authenticate users, manage user pools, and perform common Cognito operations in R. Empower your R applications with secure and scalable identity management using Rcognito.

Installation

You can install the RCognito package directly from GitHub using the remotes package:

# Install RCognito from CRAN
install.packages("RCognito")

# Install RCognito from GitHub
install.packages("remotes")
remotes::install_github("SanjayShetty01/RCognito")

Setup AWS Credentials

Before using the RCognito package, make sure to set your AWS credentials. You can do this in either of the following ways:

Method 1: Set Credentials in .Renviron File

Create or edit the .Renviron file in your R home directory and add the following:

AWS_ACCESS_KEY_ID="your-access-key-id"
AWS_SECRET_ACCESS_KEY="your-secret-access-key"
AWS_REGION="your-region"

Method 2: Use Sys.setenv() Function

Alternatively, you can set the AWS credentials programmatically using the Sys.setenv() function in your R script or session:

# Set AWS credentials
Sys.setenv(AWS_ACCESS_KEY_ID = "your-access-key-id")
Sys.setenv(AWS_SECRET_ACCESS_KEY = "your-secret-access-key")
Sys.setenv(AWS_REGION = "your-region")

Usage

1. Sign Up a New User

The sign_up_user function allows you to sign up a new user in AWS Cognito. It accepts the client_id, email, username, and password parameters.

library(Rcognito)

# Sign up a new user
sign_up_user(
  client_id = "your-client-id",
  email = "user@example.com",
  username = "johndoe",
  password = "password123"
)

Arguments:

• client_id: Your AWS Cognito App client ID.
• email: The user's email address.
• username: The user's desired username.
• password: The user's password.

---

2. Confirm User Sign-Up

Once a user has signed up, you need to confirm their sign-up using the verification code sent to their email. The confirm_sign_up_user function helps with this.

# Confirm user sign-up
confirm_sign_up_user(
  client_id = "your-client-id",
  userpool = "your-userpool-id",
  username = "johndoe",
  verification_code = "123456"
)

Arguments:

• client_id: Your AWS Cognito App client ID.
• userpool: Your AWS Cognito User Pool ID.
• username: The username of the user to confirm.
• verification_code: The verification code sent to the user's email.

---

3. Sign In a User

Once a user is confirmed, they can sign in using their username and password with the sign_in function.

# Sign in a user
user_info <- sign_in(
  client_id = "your-client-id",
  username = "johndoe",
  password = "password123"
)

# View user information
print(user_info)

Arguments:

• client_id: Your AWS Cognito App client ID.
• username: The username of the user to sign in.
• password: The user's password.

---

4. Change User Password

Use the change_password function to change a user's password after they are authenticated.

# Change user password
change_password(
  old_password = "old-password", 
  new_password = "new-password", 
  token = "user-access-token"
)

Arguments:

• old_password: The current password of the user.
• new_password: The new password for the user.
• token: The user's access token.

---

5. Forgot Password Request

If a user forgets their password, use the forgot_password function to initiate the password reset process.

# Initiate forgot password request
forgot_password(
  client_id = "your-client-id", 
  username = "johndoe"
)

Arguments:

• client_id: Your AWS Cognito App client ID.
• username: The username of the user who forgot their password.

---

6. Confirm Forgot Password

After receiving a confirmation code, use the confirm_forgot_password function to set a new password.

# Confirm forgot password with new password and confirmation code
confirm_forgot_password(
  client_id = "your-client-id", 
  username = "johndoe", 
  confirmation_code = "confirmation-code", 
  new_password = "new-password"
)

Arguments:

• client_id: Your AWS Cognito App client ID.
• username: The username of the user confirming their forgot password.
• confirmation_code: The confirmation code sent to the user.
• new_password: The new password the user wants to set.

Use Cases for RCognito

1. Authentication for Shiny Applications

RCognito allows you to integrate AWS Cognito for user authentication in Shiny applications. It enables secure user sign-up, sign-in, password management and session management, making restricting access to sensitive features based on authenticated user roles easier.

---

2. Securing Plumber API Endpoints

RCognito can be used to secure API endpoints in a Plumber service by validating AWS Cognito authentication tokens. This ensures that only authorized users can access specific API endpoints and perform actions that require authentication.

---

3. Integrating Cognito Authentication with R Scripts in Backend

When using R scripts for backend operations (e.g., data analysis, API interaction), RCognito facilitates secure authentication by verifying user credentials before allowing access to sensitive tasks or data.
