One Time Password

A one-time password (OTP) is the password used in a credential pair that is valid for only one login session or transaction. OTPs are used to minimize the risks of traditional, static password-based authentication by making them variable per operation. As an added layer of security, OTP implementations can also incorporate two-factor authentication (2FA) to help verify the identity of the individual using an additional trusted source.

The most significant benefit that is addressed by OTPs compared to unmanaged passwords is that they are not vulnerable to replay attacks. In other words, a threat actor who manages to capture an OTP used for a valid session cannot reuse it since it is no longer valid for future sessions or operations. OTPs themselves are typically random and also not susceptible to pattern-based password attacks, nor dictionary attacks. This makes them ideal for some of the most secure and privileged activities needed within an organization.

PowerBroker Password Safe is designed to automatically manage and rotate passwords across enterprises. The randomization of individual account passwords can be configured for extremely complex passwords that are essentially not human readable (assuming the resource supports the complexity and length). In addition, the PowerBroker privileged password management solution allows for only a single checkout instance of a password, and that once a session is complete, the password is automatically rotated until the next session request is granted.

In essence, PowerBroker Password Safe allows for OTP for any privileged account session and can also be used with 2FA to provide a high confidence level of the user’s identity. The simple feature, “Change password after any release” provides this functionality and is illustrated in the screenshot below:


If you consider the benefits of OTPs and PowerBroker Password Safe, every customer can enhance their security posture by providing a unique password for every session and every single connection. This is a very simple security model, but incredibly effective in stopping a threat actor from compromising accounts within your environment using attacks that leverage static (or stale) passwords.
