What is LastPass?
LastPass is a long-established, widely used password manager that securely stores your passwords and personal information and autofills them across your devices, helping protect your accounts from the dangers of weak and reused passwords. The average person has far too many online accounts to remember a strong, unique password for each, so people reuse weak passwords — one of the leading causes of account breaches. LastPass solves this by generating, storing, and filling strong, unique passwords for every account in an encrypted vault, making good password security convenient enough that people actually maintain it.
The platform stores your credentials and sensitive data in an encrypted vault unlocked by a single master password, then autofills logins and forms as you browse on your computer and mobile devices. It can generate strong, unique passwords for each account, store secure notes and other sensitive information, alert you to weak or compromised passwords, and securely share credentials with family or team members. LastPass offers plans for individuals and families as well as for businesses that need to manage and secure credentials across an organization, making it a versatile option for both personal and workplace password security.
LastPass is used by individuals, families, and businesses that want to improve their security and convenience by managing passwords properly rather than relying on memory and reuse. The value is making strong security practical: it solves the universal problem of weak, reused passwords by making unique, strong passwords effortless, while saving time through autofill and helping you keep your accounts secure. Because compromised credentials are behind so many breaches, using a password manager is one of the most impactful steps anyone can take for their security. For people and businesses who want a convenient, established way to secure their accounts and simplify logging in, LastPass remains a widely used, recognizable password management solution.
What is Oso?
Oso is a platform and framework for building authorization into applications — the logic that determines who can do what, and what data they can access. Authorization is a critical, surprisingly hard part of nearly every application: as products grow, permissions become complex (roles, hierarchies, sharing, multi-tenancy), and getting them right is essential for security but tedious and error-prone to build and maintain. Oso provides tools and infrastructure to model, build and enforce authorization cleanly, so developers don't have to reinvent this complex logic from scratch.
Oso lets developers define their authorization rules in a clear, declarative way and enforce them consistently throughout their application, handling common patterns like role-based access control, relationship-based permissions, and multi-tenancy. By centralizing and structuring authorization logic — rather than scattering ad-hoc permission checks throughout the codebase — Oso makes permissions easier to reason about, maintain and get right, reducing both security risk and developer pain. It offers libraries and a cloud service to fit different needs, helping teams build sophisticated authorization without building all the underlying machinery themselves.
Oso is used by development teams that need robust, maintainable authorization in their applications and want to avoid the pitfalls of building it ad hoc. By providing a principled way to model and enforce who can access what, it helps teams ship secure features faster and keep their permissions correct as their product and requirements evolve — which is increasingly important as applications grow more complex and security expectations rise. Its developer-focused approach makes a traditionally thorny problem more tractable. As authorization remains a universal and challenging need in software, dedicated tools and frameworks for it are genuinely valuable. For development teams that want to build and enforce application authorization cleanly and reliably — modeling who can do what without reinventing the wheel — Oso offers a capable, well-designed and developer-friendly solution.
