MasterPassword.app VS YieldStack

• Security
  MasterPassword.app uses a deterministic password generation algorithm, which means passwords are generated on-the-fly using a master password and a set of rules, eliminating the need for stored password files and reducing the risk of database thefts.
• Portability
  Since the app generates passwords through an algorithm rather than storing them, you can access your passwords on any device with just your master password, providing seamless synchronization without cloud storage.
• Open Source
  MasterPassword.app is open source, which allows for transparency and community auditing, leading to potentially higher security due to peer review.
• No Dependence on Online Services
  The app does not require any online services to store or retrieve passwords, making it functional even without an internet connection and eliminating risks associated with third-party service breaches.
• Cost
  Being an open-source and free application means there are no costs associated with using MasterPassword.app, making it accessible to everyone.

Possible disadvantages

• Learning Curve
  Users need to understand the deterministic algorithm and how it works, which may be confusing for non-technical users compared to the traditional password managers that handle everything automatically.
• Limited Features
  Unlike other password managers, MasterPassword.app may lack advanced features such as password-sharing, secure notes, form-filling, and integration with other applications and services.
• Master Password Vulnerability
  If the master password is compromised, all generated passwords can potentially be exposed, placing a significant burden on the strength and security of this single password.
• User Experience
  The user interface may not be as polished or intuitive as other commercial password managers, which can detract from the overall user experience.
• Recovery Challenges
  Recovery options are limited primarily to the master password, meaning if a user forgets their master password, it could be very difficult or even impossible to recover access to their generated passwords.

• Unverified: possible specialization
  I can't browse yieldstack.ai and have no reliable information about this product, so I can't confirm its features. If it is a focused tool in the yield or optimization space, a narrow focus can mean a simpler, more purpose-built experience than a general-purpose platform. Check the site to confirm what it does.
• Unverified: possible AI-driven automation
  The .ai domain suggests AI or automation features, which could save time on analysis or decisions if they work as advertised. This is an inference from the domain name, not a confirmed feature. Verify it against the product's documentation or demo.

• Considering security and memory, is it better to have a pass phrase (6 words that don't make sense together) or a password (14 characters, but randomly generated)?

  Have a look at MasterPassword. You don't need to remember a site's password with it. You can write down, (in abbreviated form) the constituents for generating a password. Source: over 5 years ago
