Passport

Setting up Passport requires configuring multiple middleware components like cookie-parser, body-parser, and express-session, which can be verbose and error-prone, as seen in the usage snippet.

While there are 480+ strategies, their maintenance and documentation quality vary, leading to potential inconsistencies and bugs, as not all are officially maintained by the core team.

Passport focuses solely on authentication and leaves user storage, registration, and management entirely to the developer, requiring additional work for a complete auth system, as admitted in its minimalist design.

Persistent login sessions rely on express-session and custom serialization functions, which might not align with modern stateless authentication trends like JWT, adding overhead for some use cases.
