I am writing code to login into router and grab some settings. My code,that I wrote for HTML login does not work with the router login.
I have included the image. What is it ? Can I have code in c#, python or C to login into it ?
It's Basic access authentication. And yes, you can use whatever language you are comfortable with as long as you can specify custom HTTP headers for the request.
As Jifri said, it's Basic access authentication. You can log into it by sending the username and password as part of the URL you request:
http://username:password#url.com
See discussion here too: Username and password in https url

I followed this tutorial https://yii2-framework.readthedocs.io/en/stable/guide/tutorial-advanced-app/ but it doesn't say anything about backend admin login details.
How to setup backend admin login details?
You have to install and MIGRATE RBAC extension, after that register user with username admin. Take his id from DB and follow this tutorial:
https://habr.com/ru/post/235485/
how to set up role based access. I guess that's what you trying to implement.
Yii2 templates basically is a starting point to develop an app, not a pre-made cms that has default logins.
In this case, if you have executed migrations as outlined in the tutorial
Apply migrations with console command yii migrate.
Then you would have a user table in your database. You could create a new user there with a bcrypted password, and then use that to login to the application.

My main problem is getting the token. I can’t go further than this step.
In the Linkedin API's docs there are two ways described to obtain the token.
Witch is the correct one?
1) https://developer.linkedin.com/docs/v2/oauth2-client-credentials-flow
2) https://developer.linkedin.com/docs/oauth2#configure
I understand that in order to use the new Linkedin API (the partners one) I should use the first one (https://developer.linkedin.com/docs/v2/oauth2-client-credentials-flow)
Here is my petition:
https://www.linkedin.com/oauth/v2/accessToken?grant_type=client_credentials&client_id={MYCLIENTID}&client_secret={MYCLIENTSECRET}
The response:
Error "access_denied"
error_description "This application is not allowed to create application tokens"
And I get stuck here.
With the second one (https://developer.linkedin.com/docs/oauth2#configure) I actually get a token:
https://www.linkedin.com/oauth/v2/authorization?response_type=code&client_id={MYCLIENTID}&redirect_uri={MYURIREDIRECT}&state={STATERETURNED}
This returns the code (and the State) which I use to make the token request:
https://www.linkedin.com/oauth/v2/accessToken?grant_type=authorization_code&client_id={MYCLIENTID}&client_secret={MYCLIENTSECRET}&redirect_uri={MYURIREDIRECT}&code={CODERETURNED}
And I get the token. But this isn’t the correct way to do it, is it?
By default you will need to use the authorization_code flow to obtain an access token. Per the documentation the client_credentials flow is not enabled by default and needs to be specially enabled by LinkedIn.

I would like the instructions of getting JWT from postman. What are the fields should i add under header and body? It will be nice if there is an example of end to end execution of JWT in postman. Thanks much!
Tipically JWT works with basic authentication, and in the response body you will obtain the JWT token (and refresh token if it is implemented). In postman you can extract these values into variables in the Tests tab of the request, with something like this:
var data = JSON.parse(responseBody);
postman.setGlobalVariable("jwt_token", data.token);
After that you can use the variable jwt_token in any place (urls, headers, body ...) with the syntax {{jwt_token}}
If you need more information about how JWT works in Node.js, you can take a look to this post: https://solidgeargroup.com/refresh-token-with-jwt-authentication-node-js

I´m currently designing a mobile application, and I´m having some concerns about securing the backend which runs the services for it to run.
My current planning is, using SSL and a basic workflow like this:
The generated token expires, because it assures that if someone physically access the phone/device, he cant be in control of the user account for too long, but, at the same time, I don't know what duration is appropriated for it, as I don't want to keep asking for credentials every day.
My questions are:
Is this a good aproach? Would you add something else to it?
Whats the ideal duration of tokens when working on mobile apps?
First thing first, you should encrypt session key when you store it on device. For example, use shared preferences with encrypt option. Further info : Android SharedPreference security
Second, you may want to implement "SSL pinning" mechanism. Which means that verify SSL certificates at client side. You must be sure about that received certificate is belongs to your backend or not. So you can protect your backend URLs and parameters with that way. Further info : https://www.infinum.co/the-capsized-eight/articles/securing-mobile-banking-on-android-with-ssl-certificate-pinning or http://www.thoughtcrime.org/blog/authenticity-is-broken-in-ssl-but-your-app-ha/
Third, your design is good. But be sure about your session key generation mechanism is not vulnerability against "Session Prediction" attacks. https://www.owasp.org/index.php/Session_Prediction

Does Google Go support decoding of basic access authentication calls? How do I get the username and password from the http.Request?
Go does not seem to intercept basic authentication when it is typed as an URL in a browser, but it does allow one to get it from some other applications calling it.
For example, using a simple Python code for HTTP JSON RPC:
from jsonrpc import ServiceProxy
access = ServiceProxy("http://user:pass#127.0.0.1:8080/")
print access.getinfo()
And in Go calling:
// r *http.Request
r.Header["Authorization"]
One gets this string:
[Basic dXNlcjpwYXNz]
And
dXNlcjpwYXNz
Base-64 decoded gives
user:pass
So some basic authentication in Go is possible, although it might not be something one can rely on.
There seems to be no way to get the user-provided authentication info, but you can provide the valid username and password for HTTP Basic Authentication by calling SetBasicAuth.
