How to Integrate Auth0 & Next.js | User Authentication in Next.js with Auth0

Hey everyone, welcome back! In this tutorial, we explore the seamless integration of Auth0 with Next.js, a popular React framework for building server-rendered applications. Learn how to implement secure user authentication and authorization in your Next.js projects using Auth0, and take your application's security to the next level.
If you are not aware of Auth0, Auth0 is a powerful authentication and authorization platform that simplifies the process of adding user authentication to your applications. With Auth0, you can easily integrate features like social login, single sign-on, and multi-factor authentication, providing a secure and seamless user experience.
If you do not know about Next.js, Next.js is a React framework for building modern web applications. It combines React with server-side rendering (SSR), static site generation (SSG), file-based routing, and built-in API routes. With Next.js, developers can create high-performance applications with simplified routing and serverless endpoints.

would be so wrong if i didnt thank you for this , was going through a rough time configuring auth0 with my next js app but then i stumbled upon your video and believe me this helped a lot , thanks man , wishing you all the success!

Watching your videos makes me feel motivated to do something productive in my life and not sleep all day.

[@ArpanNeupaneProductions]

I'm glad bro

[@seanelevate]

Hey thanks man, this was a great simplified tutorial. Appreciate it.

[@ArpanNeupaneProductions]

you're welcome!

[@8bulletballers385]

Hey Arpan, you're freaking awesome! I initially found you from your 'React + Express/Node.js' linking-video! Super cohesive and clear! That said, I was wondering if you could make a video where you integrated Express with NextJS, as I can't seem to find any in-depth youtube videos (or any, in general) on that topic? Thanks!

[@ArpanNeupaneProductions]

Thanks for the idea!

[@8bulletballers385]

@@ArpanNeupaneProductions I, along with many others, would really appreciate it! Thanks, Arpan!

subscribed bro ! Thank you.I wanted quick information about Auth0 for project I was not part of and your video helped me. hope you have udemy course you are awesome !

[@spicyeric9063]

This is insane! I am so glad. Thank you for good tutorial!!!!

[@TypeScriptTV]

Thanks for this video! Do you also have a tutorial that shows how to leverage Auth0 Roles & Permissions using Next.js?

[@deejinng]

NOTE!! NOT SO RELATED. When a Nextjs app has been built(I mean using command like "npm run build" with some environment variables bundled with it). Those keys kept in Environment Variables can they be found in the bundled code ?

Hello Sir I am using this in my project but facing issue logout handler logout is clearing session but it's not redirected to another router or login

[@y0ake77]

Thanks for this awesome tutorial ❤❤

[@hugossp]

Hey mister, great tutorial. I am having problems with this. I can properly log in but the access token generated is not a correct JWT. It has signature error. Can you make a tutorial showing how to get the proper JWT to save on local storage? Many thanks!

[@ArpanNeupaneProductions]

You have to make a request to AUTH0-DOMAIN/oauth/token with your client id, client secret, grant type, and audience. This must be a POST request with Content-Type set to application/json. You can make an API route in Next.js inside /pages/api/accessToken/accessToken.ts and return it there. Your backend can either fetch it from there, or you can make relative requests on your frontend and send the token through a request to the backend.

[@kavkavy]

thank you, can you please do a tutorial on next auth with the provider "next-auth/providers/duende-identity-server6"

[@Ramon314]

I use auth0 in my server actions, in there I request the accessToken. But when the access token of the user expires, I het an error message saying "Error: The access token expired and a refresh token is not available. The user will need to sign in again.". How to fix this? I tried automatically redirecting the user to the logout endpoint but I was not able to make the user resirect from the server action since it runs on the server and not the client.

just some feedback that your keyboard noise is pretty loud

[@HarvinderGeek]

did exactly as you told on clicking the login i get 500 internal error

[@adtc]

Was excited to see this tutorial, until you said you're going to use page router. App router is the future! Moving on to find another tutorial...

[@ArpanNeupaneProductions]

Lol, it is the future. I just figured since more people are used to pages router, it’d be simpler for them to integrate. App router coming soon.

[@adtc]

@@ArpanNeupaneProductions Thank you for replying. I watched it anyway because I can't find one on App Router. Well, I scrubbed through, because this tutorial is still on the basic level and I already did all that. Is there an advanced tutorial which shows how the various other states are handled, like user failed to login, user was denied access, some error happened, etc.? I'm especially looking to solve the problem where even if I logout, when I login it doesn't ask me to choose the account to login. It just logs me into the last account. It's really annoying and I don't know how to solve the problem. Forum posts tell me nothing.

[@ArpanNeupaneProductions]

@@adtc You have to adjust Auth0 settings for that, I believe. The reason it resets is most likely because the auth access token is refreshed. You can change the expiry time for the tokens in Auth0 settings.

[@ArpanNeupaneProductions]

@@adtc There’s also another provider called Clerk which you can use to add authentication, in case Auth0 is causing trouble.

[@VadimBogomazov]

cool but does not work with next js 14

[@fullstackprojects]

how to get accesstoken ?

[@leviwins]

this is old, how about using app router as opposed to pages

[@ArpanNeupaneProductions]

You're right! This video was recorded during the beta phase of app router and as most of my audience had used the pages router, this was more insightful at the time. I do have a few videos down the pipeline regarding Auth0 and app router is in there as well :)
