Just a heads up. Roles and advanced feature are intentionally left out of this video because I will do an advanced and best practices follow up video. Keep coding!

I think more topics about authentication and authorization in general would be great! Its necessary for nearly every project these days but there is so little good content online or and written by unknown people that you are not sure if you can trust!

There are plenty of videos out on this topic, yet your teaching style I find best. Please continue this topic also explaining how to refresh the tokens!

Thanks Nick, very useful and thorough explanation

Great content as usual Nick! Keep it up and yes, please show us how you would do refresh token (I already implemented it but I find your implementations always cleaner and well thought of). Thanks! PS: maybe you can show how to add multiple Identity providers (facebook + google + custom) all at the same time.

I like to see a new video about authorization & authentication topics on .net 8

A refresh token video would be coll. And also how to use JWT with asymmetric keys

If it had been made 4 years ago, it would have saved me a lot of headaches. Now it was very refreshing and enjoyable.

If only you could give us OpenIdDict series. There is almost no content on this topic. I believe a lot of people will appreciate it :)

Hey Nick, thanks for this video and it would be far better if you make a video about the implementation of OAuth

Instead of using an additional policy or attribute, i would suggest to add the custom claim "admin" as a "role" claim: var claims = new List() { new Claim(...), new Claim(...), new Claim("role", "admin"), new Claim("role", "..."), Then the controller/actions can be protected by using: [Authorize]

can't believe I've been your subscriber all this time until I needed this video. By far the most concise explanation I've seen about jwt implementation.

GOGO Nick! In postman, instead of adding header Authorization, having Bearer (space) token U may get the same results easier going to Authorization tab (1 left from Headers), choose Type Bearer Token and just past the token in the right panel

this is very confusing

the refreshing part was always tricky for me, so Im interested in dedicated video A LOT :)

Thank you for this video. It was a great help for beginning with this topic. Would like to see some deep-dive videos into this topic.

Great video and JWT Auth explanation. Thanks for the work

Thank you Nick, great video as always! It would be great also to have a video about Refresh Tokens too. Thanks

This is super helpful. Thanks!

Glad to see you mix it up a bit by going back to some of the basic stuff nearly every application needs. I've used JWT authentication in a few apps, but I learned a few new tricks from this, thanks Nick!

Thanks. You are a great teacher. If you speak a little in slower pace it will be easier for some people including me to grasp every piece of information. Just a suggestion...

Source code would've been nice!

Would be cool if you show in one of the next videos how to authenticate against Azure AD and lock down a Web-Application, so only users can use it when they are member of a specific group. :)

Finally full JWT tutorial. Thanks!

I am doing this with okta but I use a combination of middleware and filter to programmatically add the policy to the Controller/Action. I was able to inject javascript to swagger and add the header programmatically to curl so that you don't have to use the swagger authorize UI manually.

Great video!. Kindly show us how to refresh token as well. Thanks in advance

What is the code of TokenGenerationRequest class?

Nice video! i'd love to see the video for the refresh token as well

Thanks for this wonderfull new video as always ;) I really would like you to show an implementation of refreshing JWT stored in any vault you want if it is possible :D

Perfectly turned up just when I needed it.

Great video - thanks Nick. Refresh token video please :)

Would be good to see how auth and Blazor WebAssemble play together :-)

We want to see a video about refreshing tokens!

An advanced feature that I've seen a million ways that would be awesome to see you discuss would be how we can do "Enterprise Isolation". What I mean with this is that say that we have a SaaS where an "Enterprise" can have a subscription and manage their own details. For the sake of simplicity the developers want to have one shared database for all customers, which makes setup easy but it's equally dangerous because were just one missing .Where(x => x.EnterpriseId == _userEnterpriseId) from exposing other customers data. How would you setup that sort of thing? For example query filters in EF are awesome, but they don't help when patching / adding items.

Hi Nick very nice videp, please make a video about the refresh token. I am currently implementing this on a projet!

How about making a video about OpenIddict about OAuth and OpenIDConnect?

you could mention about Roles, for example Authorize(Roles = „admin”)

Hey Nick great video as always . I would love to see your approach for JWT tokens for implementing where a user can perform update and delete operations only for posts that are created by them.

This came just at the right moment!

Nice basic video. Would love to see refresh token video.

straight to the point. thanks!

Great timing my dude! Want to implement JWT in my app atm.

I needed this video 4 days ago 😅 Do one for refreshing tokens aswell

Thanks for this video! Was missing the correct issuer url in my case.

Very nice video to teach the concepts🎉

very helpful. would very much like to see more about this topics like refresh

Thank u for sharing this topic looking forward to more advanced options using this

Great video. What about api keys? Is there a clean way to have an endpoint require jwt auth, another having api-key auth requirement, and have both for the rest? An example of this would be great! I've done same like these in the past but never found a clean way to do it. I've tried looking into making an auth handler to implement permissions and having the api key be a permission but can't seem to get it the right way

Can you make a video about refresh tokens? It would be great ❤

hands down the best explanation online. ty sir!

Hey, Thanks for the great video, easy to follow, straight to the point. Would be nice if you could make one about refresh tokens.

you can actually set auth bearer token in authorization tab in postman. just saying

Good video and it world be nice to have a video about refreshing

Please add video to security refresh tokens

Hey, Can you make a video on Identity API

Why do you think it's acceptable to omit random words in speech?

we used IdentityServer now moving over to OpenIdicct... massive pain in the ...

Hey Nick, Is there a specific reason why you use a custom claim and policy for your admin users instead of simple role based authorization? Or was this just done for the sake of showing off the custom policies?

I want to see the consumer part. I mean, let's say I create a blazor/razor/react/angular/etc frontend, and now I want to use this api, ie, login, access protected endpoints, etc.

Is the sample source code available on GitHub?

Thank you indeed!

Thanks for the video! Will you do some auth videos about Blazor WASM in the future? What about some resource-based authorization?

i would have done by having the initial service implement the handler too and this way to can add this new pattern into the existing code until you need a real reason why it has to be it's own set of handler classes .. this way you can introduce this pattern into an existing code without having to through the code you already had.

Minimal API with FastEndpoints FTW!!

We need RefreshToken video ❤

What is the difference between Claim and Signature? what does each one reference?

NIck a great video!! can you show the authorization using permission based please?

This is an awesome video regarding claims and policies. The challenge though is to accept many claims under one policy; this works well when you have a user that falls under several claims. However, I think that the Authorization Attribute approach may be a better solution. With that said Nick, are those attributes "stackable" on a controller method?

Hello! Love the video, I am introducing myself with it, I have some doubts about the project of Identy.API Someone has the code source or can explain how implement it?

I didn't get the names of where to store the keys instead of the configuration? (did you say aws secrets manager?) What would you use to store those keys for a local project?

I think it's time we stopped pushing JWT now we know better and have done for some time. That said, the functionality within netcore for authetication and authorization are quite nice.

As what did you declare the CustomClaim in your TokenGenerationRequest ?

Hello! Thanks for sharing this video! Would you also be willing to share the Github repo for this examples as well?

Why would you HAVE to move to an identity provider if you could just issue your own tokens?

What about asymmetric encryption. What is the best practice for api projects.

Now waiting for Refreshing Token because without it this is only half implementation :)

So authentication/authorization works on the api via an Identity provider. Fine, I'm okay with that. What I don't understand is how is my client application, say a razor pages app, supposed to work with this? I send a username and password to my API to login, the API returns the token and we're all great. What do I do with it then? I can embed it in an HttpOnly secure cookie, but that isn't enough to authorize the user to perform actions on the razor pages app, right? So how do I configure my app to use the token from the API to infer authorization status of a user?

Hey Nick, do you recommend using blazor for frontend?

It looks like a lot boiler plate code. There are not standard components for this?

can we do refresh tokens too? i would like to know if some implementation i used is a good one

No word on [Authorize(Roles = "Role1,Role2")] or User.IsInRole? ... which maps to the (default) role claim in the JWT

How to manage the token in JavaScript? How to make external complements use the token and be resistant to refresh. Thanks

Thanks for the great video. I have one question. Why can't a hacker get the token from the network tab like any developer, but in the production environment? I know it is not possible and it would have been a disaster but why? Thanks again.

@Nick could you do a video on a hybrid approach? Oidc like Okta/Auth0 for authentication (AUTHN) and local claims for Authorization (AUTHZ)

The purpose of this video wasn't JWTs, HOWEVER, I think it's worth mentioning that no one uses symmetric keys with JTWs in the real world (like it shown here), it's always asymmetric. The importance is that when you build your API you do NOT need to protect the public key used to verify the signature which greatly simplifies the implied complexity mentioned here to protect that key. In practice the public keys for modern token validation are publicly accessible at the .wellknown endpoint, there are multiple keys, and they are rotated. Otherwise, great video!

Hi Nick, you always say the link to the code in the description below, but sorry, I have never seen a link to the code in the description in any video, Am I miss something?

Hey, how would we do that in a azure function? i'm struggling with that

Guys what would you recommend where i have role per resource (entity in table) which can be created by any user but then only Owner of entity can perform delete, update etc. For now I have just database call validating if user has Owner role in the resource, but wondering if there is better approach

It's posible to have both identity validation for login UI and JWT authorization? I was trying this last weekend, and couldn't make them work at the same time. Love your content 🤙🏻

idea - how many clims is too much claims and when we should store only id there and go for permission to database

When do you really create and manage this yourself compared to using oidc providers like IDS or Auth0?

Great video and very helpful. You just move really fast though. It's hard to see what you're doing.

I already have oauth as my default authentication scheme for this one dotnet core app, can I tack jwt on to that?

Can you make a video with Blazor WASM with Cognito Authentication thats uses groups to profiling the app content? Thank you!

Can you show how to "Refresh JWT Token" ?

am I the only one who has a hard time finding the correct repository of this tutorial?

Wait, we can use the James Webb Telescope to authenticate ourselves? 😅

@nickchapsas first of all thank you for sharing such good stuff always ... I am dying to see your video for refresh tokens have you made it if yes please give me link

I am currently implementing something similar at work😅

Great content. How to solve the case when the endpoint is accessed by the admin or the owner of the resource (move), e.g. downloaded from the DB?
