JWTs are complex. Encrypted session cookies are a proven solution, widely used, and easy to implement yourself using only core libraries (http, crypto, JSON) without introducing security flaws IFF you are an experienced programmer and don’t deviate from the norm. JWTs are complex. Too complex to implement yourself, so you need to introduce dependencies. Dependencies are usually huge, and each line of code introduces risk (even if that line is for a configuration you don’t use!). Using JWTs at all is far more risky, even if you are an experienced programmer. If JWTs provides immense benefits over session tokens for your use case, that risk might be worth it. However, for most web apps, session tokens are good enough.
