When user requests to the server for a token sending user and password through SSL, the server returns two things: an Access token and a Refresh token.Īn Access token is a Bearer token that you will have to add in all request headers to be authenticated as a concrete user. So, I'll try to explain how Bearer tokens and Refresh tokens work: It has to be a base64 encoding of some attributes? Should it be Kind of string for the bearer token? Can it be a random string? Does Suppose I am implementing an authorization provider, can I supply any I guess bearer tokens are not hashed (maybe partially, but not completely) because in that case, it will not be possible to decrypt it and retrieve users properties from it.īut your question seems to be trying to find answers on Bearer token functionality: If the token doesn't verify, the service should respond to the request with an HTTP response code 401 (Unauthorized).īearer Tokens are part of the OAuth V2 standard and widely adopted by many APIs.Īs I read your question, I have tried without success to search on the Internet how Bearer tokens are encrypted or signed. If using bearer tokens, verify that the request is coming from the authentication server and is intended for the the sender domain. All bearer tokens sent with actions have the issue field, with the audience field specifying the sender domain as a URL of the form For example, if the email is from the audience is. This is a cryptographic token produced by the authentication server. The string "AbCdEf123456" in the example above is the bearer authorization token. User-Agent: Mozilla/5.0 (X11 Linux x86_64) AppleWebKit/1.0 (KHTML, like Gecko Gmail Actions) For example: POST /rsvp?eventId=123 HTTP/1.1Ĭontent-Type: application/x-www-form-urlencoded It's your authentication server that will have to generate them and validate them so how it's formatted is up to you.Ī Bearer Token is set in the Authorization header of every Inline Action HTTP Request. oh and if one hasn't been used for say 6 months I would remove it from your system. For example a user can authenticate the application up to 30 times and the old bearer tokens will still work. Only thing I can think of is that its nice to allow more than one. Google Refresh token looks something like this: 1/mZ1edKKACtPAb7zGlwSzvs72PvhAbGmB8K1ZrGxpcNMĬopied from comment: I don't think there are any restrictions on the bearer tokens you supply. Example: I can't just take a bearer token created for your application and use it with my application it wont work because it wasn't generated for me. This way the server knows that the application using the bearer token is the same application that the bearer token was created for. To get an access token you send the Authentication server this bearer token along with your client id. You use the bearer token to get a new Access token. Access tokens are short lived (around an hour). In order to access an API for example you need to use an Access Token. It isn't random it is created based upon the user giving you access and the client your application getting access. The Bearer Token is normally some kind of opaque value created by the authentication server. A Bearer token basically says "Give the bearer of this token access". Bearer Tokens are the predominant type of access token used with OAuth 2.0. When a user authenticates your application (client) the authentication server then goes and generates for you a Token. The Bearer Token is created for you by the Authentication server. Require a bearer to prove possession of cryptographic key material The token (a "bearer") can use the token in any way that any other A security token with the property that any party in possession of
