I'm building an app which doesn't rely on a login system (no database) that will save user's data on dropbox/google drive and others
So when an user open the app he "login" using the cloud service.
Since I'm not going to use any database I was wondering if it's secure to store user oauth token (not the app one) in cookies.
If anyone gets access to cookies he can get access to user data on my app ot it will need also app tokens?
It depends on what OAuth version is used and what OAuth flow is used. Generally the OAuth access tokens can be stored only if it can be secured, for example stored in the key chain on iPhone where only application/user granted the access can get it. Same applies to refresh token in OAuth2

I have my web application. Now i want to integrate salesforce into my web app so that i can push data from my app to any salesforce org after the authentication(OAuth).
I found 2 ways:
1. Connected Apps
2. via wsdl generation file and use
I created a connected app from my developer account and i authenticated using consumer key, cusumer secret key(from my connected app) and username of user and secret token of the user account.
I tried with another free trail account, It's validating and fetching the details and post data also working.
My question is, shall i deploy my connected app into app exchange, then only i caan use REST APIs ?
generating wsdl and coding around is the better option than the above ?
Is there a option, only one time authentication enough for any number of sessions and use the REST APIs?
Please suggest me a best way to proceed.
You're mixing up a couple of independent issues here.
If you're going to authenticate via OAuth, you must have a Connected App.
A SOAP API login() call requires you to store a username and password, which is undesirable.
There is no way to "permanently" authenticate, i.e., to get a session id that never expires. Your app must always be ready to get a new access token via the OAuth refresh token it obtains and stores (via, for example, the Web Server OAuth flow), or to reauthenticate via JWT flow.
Connected Apps are global metadata in most cases. You don't need to deploy a Connected App into a target org in order to authenticate using its Client Id and Secret into that org. The only exception I'm aware of is if you want to use the JWT flow with a certificate and preauthorized Profiles and Permission Sets.
Based on what you've shared, I don't see any reason for the AppExchange to be involved.
We are developing a web application in AWS which stores its users in Cognito. As part of this, we are required to have an integration with an existing desktop application, where the administrator of a client can create a read-only user for the website for data sent from the desktop app.
Because of this read-only user requirement, there has to be a user associated with the authentication for each instance of the desktop app installation. This is no problem, as we are happy that all local users of the desktop application have their data logged to the same place in the web application. The tricky part is that we are not able to have the username and password as common knowledge for the end-users of the desktop app.
It has been suggested that we could use token-based access to allow the desktop app to access our API, but these are all time limited and we would not be able to have the user re-authenticate each day. However, another suggestion is to create our own "key" which contains the username and password of the Cognito user in such a way that the application will be able to use it, such as encrypting the username and password with the decryption key available to the desktop app so that it can authenticate as that user itself without the end users having access to the account details.
I would like to know if there is currently any best practice way of handling a requirement like this that is better than what we currently have available.
To summarise:
We have an AWS API with Cognito Authentication
We have a desktop application which needs to access the API
We cannot have users know the details of the account being used to access the API
We need a way to provide a key that will allow the desktop application to authenticate itself against the API in such a way that the token will not need to be refreshed over time
Thanks for any help.
Unfortunately this requirement:
"We need a way to provide a key that will allow the desktop application to authenticate itself against the API in such a way that the token will not need to be refreshed over time"
is not going to be possible with Cognito. Assuming you are using Cognito user pools, the id and access tokens obtained on authentication are only valid for 1 hour, then they have to be refreshed using the refresh token. The refresh token can be configured to be valid for a really long time (years even) so you could setup a flow where:
The app authenticates itself against Cognito once
Gets a refresh token that is valid for a really long time
Throws away the original encrypted username/password
Uses the refresh token to get a new id/access token every hour
You would have to store the refresh token on the client somewhere though. And probably have a support mechanism where this process could be restarted on the client in case the refresh token is lost.
If you are using Cognito user pools, you are going to have to do token refreshes. Same is true if you are using Cognito identity pools - the AWS credentials provided by the identity pool are only valid for 1 hour, then they have to be refreshed.
I am trying to develop mobile native apps with ionic2 and django rest framework. And I found django-rest-framework-jwt library that support great jwt authentication. However it doesn't refresh token automatically so that users of mobile apps should type their username and password whenver the token expires..
I already checked another stackoverflow question below.
JWT (JSON Web Token) automatic prolongation of expiration
Is there any way that users don't have to type their username and password again? Or Is it ok let token not to be expired and save it local storage of mobile apps so that users don't have to login again?
Thanks in advance!
I've run into the same scenario with our Django and DRF-based projects, and we wanted to implement Single sign-on using JWT. Since the djangorestframework-jwt library had very little focus on providing SSO capabilities between different projects, I have created a new library for this that properly sets up trust definitions and public/private key pairs.
This library provides two types of JWT tokens:
non-expiring session tokens for your primary login application (aka. "refresh tokens")
short-lived authorization tokens for accessing your other apps (these contain permissions given by the primary app)
The client is expected to first login to your primary login application by POSTing an username and password. The client will receive a permanent session token that will allow subsequent requests to the same server be authenticated. These tokens do not contain any permissions/authorization information and cannot be used for SSO into other apps.
Afterwards, the client is expected to obtain and keep updating authorization tokens using the session token. These secondary tokens are short-lived (15mins..1 hour) and contain the permissions that the user has at the time of issuance. These tokens are used to access other services, which then trust the permissions in the JWT payload for the lifetime of the token.
The current version is v0.0.3 (alpha), but we are moving very fast towards a beta and finally production quality release. The API is already relatively stable and should be final by June 30th 2016. The framework will also have full test coverage in the coming weeks, when we reach the beta stage.
Please check the project page and github for the README.

Please let me know if this would fit your use case, and if it has all the features required. I'll be happy to help with the setup.
I am doing some work in Django, using the Django Rest Framework.
Users login via Oauth2 to facilitate integration with mobile applications.
I am using the Oauth2 authentication library that is packaged together with the Django Rest Framework.
To logout a user, I am expiring their access tokens, is this the correct way of doing things?
It's not correct. Normally, the access token expires when it reaches its expiration time.
Or in some these cases:
1. User revoke this access token.
2. Users change their password.
3. When refresh token is revoked, its issued access tokens will be deleted.
And here is a reference about log out.
I think what you mean is that you are creating a oauth2 provider?
If I am correct I would recommend switching to using token authentication. To create a oauth2 provider there are many restrictions and rules to follow and I assume when you create a oauth2 provider that it will be a public system that can be used by many people (that can and will misuse your service if it's has leaks)
I want to be able to authenticate users of an angular.js application using oauth, but I do not want to store any tokens on the frontend because I have seen that it can be fairly complicated to do so securely. Is there a way to pass some sort of credentials of a user to my django web application, where is can authenticate the user with some oauth provider and save that information in a session? To make it simple, here is the process I want
User is logged into some oauth provider, i.e. stackexchange
They click a "login with stackexchange" button on the front end angular app
Their login credentials are sent over to the django application through a restful api
The django app which receives these credentials attempts to get a token using rauth
If the server receives a token, the user is logged in and their information is saved in a session, otherwise they are given an error
Is this sort of process supported by OAuth2 providers?
Step 3 is incorrect: that authentication process is handled entirely off-site, on the OAuth provider's infrastructure, e.g. StackExchange.
This kind of flow is certainly possible. I would check out the Facebook example, which uses Flask, but provides a similar framework for how you might go about this in Django.
