Authentication method

As per this link we need to set the authentication method to ‘None’ to resolve teh ‘unauthorized’ issue. Token Endpoint Authentication Method Post vs None

What’s the purpose of authentication method and what is the downside to setting the value to None.

Hey there @Anup!

I’ll echo the question with regards to what is your use case and what type of application (SPA, web, etc.) are you using?

The token endpoint authentication method determines how a client authenticates with the token endpoint - The ‘none’ method is essential for applications where storing credentials isn’t feasible (public clients). Other security mechanisms like PKCE and strict redirect URI validation are used to ensure the security of the OAuth flow.
