What Is an OTP?
A one-time password (OTP) is a short code that expires quickly and can be used only once. OTPs reduce risk when combined with regular passwords and two-factor authentication.
Common OTP Use Cases
- Login verification on sensitive accounts
- Transaction confirmation for banking actions
- Password reset confirmation
OTP Security Best Practices
- Never share OTP codes over calls or messages
- Use authenticator apps when possible
- Keep backup codes in a password manager
For stronger account protection, use unique passwords from the password generator and check weak credentials with the strength checker.
