Maybe there's no id , but a userId or similar, or a sub claim , which is a registerd claim name to be used to identify the principal: I'm building a Python application using FastApi and I'm using JWT and OAuth2 password flow to authenticate the users, as specified in their documentation. Rest (ES256, ES384, ES512, RS256, RS384, Here you can check how to encode, decode, sign and validate JWT (JSON Web Token). If the token was generated by Auth0 then it uses your tenant private key which is automatically Here is a small copy and paste ready function you could use: private static string CreateJwt(IEnumerable<Claim> claims, DateTime expiresAt) { // Creating the symmetric key and signing credentials var veryUnsecureSecureString = "YOURSYMMETRICKEYHERE"; var symmetricKey = new JWT_AUTH = { # how long the original token is valid for 'ACCESS_TOKEN_LIFETIME': datetime. The I tried to use a few libraries like jose-jwt and Microsot Jwt class for creating JWT token, but I can't wrap my head around it.
