How can i refresh the skype bot token obtained via https://login.microsoftonline.com/common/oauth2/v2.0/token
This token has grant_type=client_credentials so you don't need OAuth2 refresh logic for it. Just request a new token when the old one expires.
Take a look to the OAuth 2.0 Authorization Flow. There you will find all the details around refreshing the access token.

I am using a simple JWT auth firebase. backend checks if its a valid user and gives back an access token using JWT. Now I want to implement a refresh token. How can I do it? What should be the content of the refresh token? When I sign a new access token and go to protected a page but when fresh it, it go to login page again.
what should I do to also sign a refresh token? please help me anyone.
when you are generating JWT auth token generate refresh token with 1d or with no expiry time according to you requirement. After this send JWT and JWT-REFRESH token in the response of login API, after this make an API in your backend which accepts the refresh token from header or from body and in response generate a JWT token, in case of bad refresh token return 401 status code.
At client side if you are using axios, you can use axios-interceptors as a middle to detect if 401 is coming from any API, then in that case hit the refresh JWT token API to generate new auth token.
If refresh token API gives again 401 response then handle it as REFRESH token is also expire and redirect the user into login page.
I have created an appian Connected System for DocuSign authentication with Authenticate Code Grant. I am able to authenticate & hit APIs successfully. But the issue is my token gets expired every 8 hours, then I have to go and authenticate from Connected System file again.
Please help me understand how can I refresh my token when its expired/about to expire.
I can explain how refresh tokens are used to generate a new access token.
However, this may not be possible with Appian, I am not sure about that, because I'm not sure about how Appian works.
First, you have to store the refresh_token you got when you used Auth Code Grant to get the original access_token that expired. That token can used to get another access_token later.
To get a new access token, use the refresh_token as you would an authorization code, but with a grant_type value of refresh_token and a refresh_token parameter that holds the contents of the refresh_token.

I may be answering my own question here but would like some assurance.
For a Azure event hub producer client (.net) using OAUTH token authN will token refresh be performed within the MSAL Classes OR would it be connection/message?
Thanks
MSAL handles token refresh.
When you ask for a token silently, MSAL will first check if it has a token in cache that is still valid.
If yes, it'll return that.
If not, it checks if there is a refresh token in cache.
It'll then try to use that to get new tokens, cache them, and return them.
If the refresh fails, you will get an exception.
Azure AD is granting my application access tokens and a refresh token. When I use the refresh token to get a new access token, in return I get a new access token and a NEW refresh token.
Azure AD does not specify like Google Suite how many refresh tokens are allowed. But to the root of the problem, I don't want a refresh token being recreated and sent back, every time I use a refresh token. What is happening here? How do I stop this?
Returning of new refresh token is part of the OpenID Connect Protocol Specification which references the OAuth Authorization Framework section 5.1 for clarity.
Indeed the return of a refresh token is optional, but the implementation in Azure AD is so that it always returns a refresh token. I personally see no issue with it. Just throw away the last saved refresh token and keep the new one you got.
You cannot control this, it is done by design. It is also in complience with the OAuth 2.0 spec:
The authorization server authenticates the client and validates the refresh token, and if valid, issues a new access token (and,optionally, a new refresh token).
As for "floating out there", this only happens if you make it happen. If your app "forgets" the old refresh token then it is gone.
I'm using Oauth2 to handle authentication in my system. While the authentication works, I'm worried about the security of my refresh token endpoint. The front-end calls this endpoint to get a new access token after it expires.
My question is how would you prevent someone from calling that endpoint and getting a new access token? Would you use the access token to authenticate yourself? At the moment I'm using these tokens to authenticate API calls on a separate service.
The endpoint currently supports csrf, but that's probably not enough.
Thank you!
The refresh token is used to get the new access token. That is where the authentication happens.
You can decrease the time that a refresh token is valid.
You can also choose if you want the refresh token to be renewed or not with each call to refresh the access token.
Unauthenticated clients cannot call the refresh token endpoint and get a new access token.
