OTP-Example

A Python script to demonstrate basic OTP (One-time password) generation, verification and delivery of emails using the Simple Mail Transfer Protocol (SMTP) library.

To run:

Preferably, use Python 3.10.8 or higher.

Run the commands from below into your shell.

  git clone https://github.com/Ryukaizen/otp-example.git
  cd otp-example
  cp .env.example .env
  pip install -r requirements.txt

Add the environment variables to .env file. Then run:

  python main.py

Environment variables

Rename the .env.example file to .env first.

To run this script, you will need to add the following environment variables to your .env file:

SENDER_EMAIL = [email protected]

SENDER_EMAIL_PASS = password

Default variables:

EMAIL_OTP_SUBJECT = "Your OTP for OTP-Example:"

EMAIL_SERVER_HOST = smtp.gmail.com

EMAIL_SERVER_PORT = 587

For Gmail users:

Make sure to enable IMAP in Gmail settings.

Then follow these steps:

  1. Activate two-step verification of the corresponding Gmail account.
  2. Create an app password.
  3. Replace the password with the generated app password (a sixteen-digit password).
