OTP stands for One-Time Password. It is a unique code that is sent to your mobile device or email address to verify your identity and confirm that you are the authorized user.
How OTPs Work:
- Authentication: OTPs are primarily used for two-factor authentication (2FA), an extra layer of security that adds an additional step to your login process.
- Security: OTPs are generated randomly and expire after a short time, making them difficult for unauthorized individuals to intercept or use.
- Verification: When you try to log into an account or perform a sensitive action, the system will generate an OTP and send it to you. You then enter the code to complete the process.
Common Uses of OTPs:
- Online Banking: Banks use OTPs to verify transactions and protect your account from unauthorized access.
- Social Media: Some social media platforms use OTPs to secure your account and prevent unauthorized logins.
- E-commerce: Online stores use OTPs to verify purchases and ensure that the transaction is legitimate.
- Email Accounts: Email providers use OTPs to secure your account and prevent unauthorized access.
Examples of OTPs:
- SMS: You receive a text message containing a six-digit code.
- Email: You receive an email with a unique code.
- Authenticator Apps: You can use a mobile app like Google Authenticator or Authy to generate OTPs.
