In Nexus I store tokens in the database. Logging out deletes the record.
Isn’t that just sessions but with extra steps?
Well the JWT has encrypted info that is verified on each call, so there is extra security.
yeah, JWT's are a nice standard way of doing that, but it's functionally not really different than the HTTPS + Session + Nonce pattern that's been in use for about 10 years now, and, provided you pick a secure function to make the hash for the nonce, the nonce may be more secure since it rotates with each payload and the JWT's encryption lasts for its lifetime.
The JWTs I use expire after a given time and are renewed. I agree, there's not much difference. Its more like a standard way of generating tokens.
