What Is OTP Authentication?
OTP authentication is a secure login method that uses a one-time password for each session. These passwords change with every use, making them resistant to phishing, password replay, and brute-force attacks.
Unlike SMS-based or software OTPs, hardware OTP tokens offer the highest level of physical security and user control.
- Complies with OATH standards (HOTP, TOTP, OCRA)
- Does not rely on mobile phones or networks
- Works offline and in air-gapped environments
Why Choose Hardware OTP Tokens?
Hardware tokens provide tamper-resistant, portable security. Ideal for high-risk industries, enterprise systems, or offline authentication environments.

OTP Authentication: Secure Your Platform with One-Time Passwords
A one-time password (OTP), also known as a one-time PIN, one-time passcode, one-time authorization code (OTAC), or dynamic password, is a password that is valid for only one login session or transaction on a computer system or other digital device. One-Time Password (OTP) Authentication avoids several shortcomings associated with traditional static password-based authentication. Many implementations include two-factor verification by ensuring that the one-time password requires access to something a person has (e.g., a hardware device or smartphone) and something they know (e.g., a PIN).
OTP generation algorithms use pseudo randomness or randomness to produce a shared key or seed, along with cryptographic hash functions that are difficult to reverse. Without this, it would be easy to predict future OTPs from previous ones. OTPs have been discussed as both a replacement and enhancement to traditional passwords. However, they can still be intercepted, and physical tokens may be lost or stolen. Poor implementation of OTP systems leaves them vulnerable to phishing, allowing attackers to impersonate legitimate users.
