OAuth2 VS Memory.com

• Delegated access without sharing credentials
  OAuth2 lets users grant third-party applications limited access to their resources without handing over their passwords. Access tokens stand in for credentials, so a compromised client exposes far less than a leaked username and password would.
• Scoped and limited permissions
  Tokens can be restricted to specific scopes, resources, and lifetimes, so applications receive only the access they need. Users and administrators can also revoke tokens at any time without changing the account password.
• Widely adopted industry standard
  OAuth2 is supported by major providers such as Google, Microsoft, GitHub, and Facebook, and by most identity platforms. This broad adoption means mature libraries, SDKs, tooling, and community knowledge are available for nearly every language and framework.
• Flexible grant types for many use cases
  The framework defines multiple flows, including Authorization Code (with PKCE), Client Credentials, and Device Code. These cover web apps, single-page apps, mobile apps, server-to-server communication, and input-constrained devices.
• Enables single sign-on and API ecosystem integration
  Combined with OpenID Connect, OAuth2 supports federated login and single sign-on across services. It also provides a consistent way to secure APIs and let third-party developers integrate with a platform in a controlled manner.

Possible disadvantages

• Complexity and steep learning curve
  OAuth2 involves many concepts, including roles, grant types, scopes, redirect URIs, and token lifecycles. Developers can easily be confused about which flow to use, and misunderstanding the spec often leads to flawed implementations.
• Easy to implement insecurely
  The spec is a framework rather than a strict protocol, leaving many decisions to implementers. Common mistakes include weak redirect URI validation, missing state parameter checks, using the deprecated Implicit flow, and insecure token storage, all of which can lead to vulnerabilities.
• Bearer tokens are vulnerable if stolen
  Standard bearer tokens grant access to whoever holds them, so leaked or intercepted tokens can be replayed by attackers. Mitigations such as short lifetimes, TLS, DPoP, or mTLS add extra implementation effort.
• Not an authentication protocol by itself
  OAuth2 is designed for authorization, not for verifying user identity. Using it for login without an identity layer like OpenID Connect leads to misuse and security gaps, and requires adopting additional standards.
• Fragmented and inconsistent implementations
  Because the specification is loose and has many extensions (OAuth 2.1 drafts, PKCE, DPoP, and others), providers implement it differently. This causes interoperability issues, provider-specific quirks, and extra work when integrating with multiple services.
