🔐 How Does OTP & Email Verification Work?
OTP (One-Time Password) and Email verification are widely used authentication methods that ensure the user’s identity is genuine before granting access to systems, platforms, or services.
📲 What is OTP Verification?
OTP is a randomly generated numeric or alphanumeric code sent to the user’s mobile number or email address. It’s valid for a limited time and for a single use only.
✅ Use Cases:
- User registration or sign-up
- Login or password reset
- Transaction approvals (banking, eCommerce, etc.)
- Two-factor authentication (2FA)
📧 What is Email Verification?
Email verification involves sending a unique verification link or code to the user’s email address. The user must click the link or enter the code to confirm ownership of the email.
✅ Use Cases:
- Account creation
- Newsletter subscriptions
- Changing email address on file
⚙️ How the Verification Process Works
- Step 1: User submits phone number or email during signup/login
- Step 2: System triggers Send API to deliver OTP or verification link
- Step 3: User receives code/link and enters it on the platform
- Step 4: System calls Verify API to validate code
- Step 5: On success, user is authenticated; otherwise, they retry or request a new OTP
