The provided text does not contain specific information about Google Authenticator, HOTP (HMAC-based One-Time Password), TOTP (Time-Based One-Time Password), two-factor authentication, or password managers. However, based on the context and Aleksander Hougen's expertise mentioned in other sections of the same article or webpage:

1. It is likely that Aleksander has written about these topics elsewhere.

2. His background in software engineering combined with a passion for digital security suggests he would have knowledge to provide insights into Google Authenticator, its applications (such as two-factor authentication), and related concepts like HOTP and TOTP.

3. The text mentions his ability to simplify complex subjects like secure cloud storage, online backup, VPNs, and password management, which aligns with the type of information he might have written about in other contexts.

4. If you're looking for specific guidance on Google Authenticator or two-factor authentication using HOTP/TOTP methods, I would recommend searching through his past articles or posts directly rather than relying solely on this extractive response.
