What is Time-based One-Time Password -TOTP??
Time-based One-Time Password (TOTP) is a temporary passcode generated by an algorithm that uses the current time as one of its input parameters. This code is used for two-factor authentication (2FA) to enhance the security of user logins beyond just a username and password.
How TOTP Works
1. Secret Key:
The server and the client (user’s device) share a secret key, which is used as the basis for generating the one-time passwords.
2. Time Factor:
The current time is divided into fixed-length intervals, typically 30 seconds.
3. Algorithm:
The TOTP algorithm combines the secret key and the current time interval to generate a unique, temporary code.
4. Verification:
When the user logs in, they provide the TOTP code, which the server then verifies by generating its own code using the same secret key and time interval. If the codes match, access is granted.
Key Features
Time-based:
The code changes at fixed intervals (usually every 30 seconds), making it difficult for unauthorized users to reuse a code.
One-Time Use:
Each code is valid only for a single login session, ensuring that even if a code is intercepted, it cannot be reused.
- Two-Factor Authentication:
TOTP is often used as part of 2FA, requiring users to provide both their password and the TOTP code to log in.
Use Cases
- Online Services:
Many online services, such as Google, Microsoft, and social media platforms, use TOTP for enhanced login security.
- Financial Institutions:
Banks and financial services use TOTP to secure online banking and transaction processes.
- Corporate Networks:
Companies use TOTP to protect access to internal systems and sensitive information.
Tools and Apps
Several applications can generate TOTP codes, including:
- Google Authenticator:
A widely used TOTP generator available for both Android and iOS devices.
- Authy:
Another popular TOTP app that supports multiple devices and cloud backup.
- Microsoft Authenticator:
Provides TOTP codes along with other security features for Microsoft accounts
