authentication-zero VS JWT

Subsequently, we need a way to authenticate our users to associate prompts with them. Rather than using an incumbent like Devise, I chose to use a different approach. The authentication-zero gem can flexibly generate an authentication system, as opposed to including it as an engine. Conveniently, it comes with options such as:

If you don’t need a good amount of features that Devise brings to the table, I‘d skip it entirely. Look up has_secure_password, that will be enough for a vast amount of applications with authentication. Maybe combine with cancancan for authorization. Once you feel you have a grip on those, re-evaluate devise or take a look at https://github.com/lazaronixon/authentication-zero which will transparently integrate into your app instead of providing a Rube Goldberg machine (that’s what devise will feel like for beginners for a long time).

I keep going back and forth between Devise and something a little more friendly like authentication-zero gem for authentication.

For those that have used the authentication-zero gem or are familiar with its functionality, what is the best way to upgrade it in a project when new functionality is released?

True. I tend to stay away from gems that try to integrate into multiple parts of your app to provide some sort of comprehensive solution. The kinds of gems I recommend are: 1) libraries (you call into them when you need them) 2) mounted apps on a url, isolated from the rest of your app 3) generators (this one seems nice, the author mentioned it in another HN thread: https://github.com/lazaronixon/authentication-zero).

I prefer to use authentication-zero, which generates code for me in the same application using has_secure_password, has good security practices, uses the same functions as Rails, and allows me to modify the flow to my liking.

To authenticate our users, we need to add jwt gem to our Gemfile

jwt is a Ruby implementation of the RFC 7519 OAuth JSON Web Token standard. bcrypt is a Ruby binding for the OpenBSD bcrypt() password hashing algorithm.

ruby-jwt is fairly easy to use on it's own without Devise. You might try that first and only add Devise if needed.

Generally speaking, the larger the application, the more internal and external services it has to talk to. External services usually have their own way of authenticating and authorizing third party API calls. With internal systems however, organisations prefer to use JWT tokens because of their inherent flexibility and versatility. A sample JWT based handshake between 2 rails applications using ruby-jwt would look like this -

Interesting. What's the difference between this and the standard ruby-jwt? https://github.com/jwt/ruby-jwt

jwt - encoding and decoding jwt oauth

Decoding JWTs is simple whit the help of an already implemented solution. In this section, I'll be using the ruby-jwt.
