How OTP works

A One-Time Password is a temporary or single-use authentication code used to verify a user’s identity during login, remote access, online banking, VPN access, and other protected transactions. FEITIAN describes OTP tokens as a way to supplement static passwords with stronger authentication.

1. User starts a login

Enters username and password

2. OTP is generated

A hardware token, OTP card or authenticator app calculates a code

3. Authentication server verifies the code

Checks the code against the configured OTP algorithm and secret

4. Access is granted or denied

Access depends on successful verification and the service’s authentication policy

Types of OTP authentication

FEITIAN documents HOTP and TOTP in its single-button token specifications, and OCRA support in its mobile and challenge-response solutions.

Type	How it works	FEITIAN example
HOTP	Generates codes based on an event or counter	C100 hardware token
TOTP	Generates codes based on time intervals	C200 hardware token
OCRA	Uses challenge-response calculations for more advanced authentication	E-signature OTP token
QR-based OTP	Scans transaction details and generates a transaction-linked authentication response	QR Code OTP token
Mobile OTP	Generates authentication codes through supported mobile software	FEITIAN Mobile OTP

OTP security: benefits and limitations

Security benefits

• Adds a second authentication factor to password-based login.
• Helps reduce the risk associated with stolen or reused static passwords.
• Hardware tokens can generate codes without installing software on the user’s computer.
• Secure seed provisioning and management help protect the cryptographic secrets used to generate and verify codes.

Important limitations

• OTP codes can still be stolen through phishing or relayed to a fraudulent website in real time.
• A compromised OTP seed or poorly secured verification server can undermine the protection.
• TOTP depends on sufficiently synchronized time; HOTP depends on counter synchronization.
• OTP is not inherently phishing-resistant. For high-security environments, consider FIDO2/WebAuthn security keys and passkeys where supported.
