Is it bad practice to use localStorage?

If you are not accessing data in localStorage way too often, data inside of it are not changing frequently. Then it is OK.

Why localStorage is not secure?

Is localStorage fast?

localStorage is by far the fastest mechanism to persist values across a browser refresh. Note that I’ve precompiled cookie regex getters in order to make cookies as fast as possible and used the browser performance API for accurate measurements. All tests do a set of a unique key followed by a get of the same key.

Is localStorage a cache?

A cache is just some data that we remember we got back from a particular request (or URL). Thankfully the browser has this wonderful and simple way to store data called localStorage. LocalStorage allows us to read and write key/value pairs to and from the browser’s storage.

This means that cookies are going to be much smaller than local storage and session storage but that’s okay for their use cases.

When should I use JWT token?

In short, JWTs are used as a secure way to authenticate users and share information. Typically, a private key, or secret, is used by the issuer to sign the JWT. The receiver of the JWT will verify the signature to ensure that the token hasn’t been altered after it was signed by the issuer.
