Auth to twitter with login/password

I'm currently using OAuth to开发者_运维知识库 authenticate people with their twitter (twitter gems) acount in my application. The problem is that for people who aren't connected or who have various accounts.

So that's my question, is that possible, to ask user their login/password to link their twitter account on my application ?

Thanks

It is no longer possible to connect to Twitter's API using Twitter credentials. Twitter's public stance on this is that you should -never- provide your Twitter credentials to anyone else, ever. This is part of their rationale for implementing OAuth.

Even if you had the user's Twitter password, you couldn't validate that it was actually their password, nor could you access their Twitter account with it through the Twitter API.

Your best bet would be to look into devise and omniauth. I've gotten it to work this way. Omniauth also allows to link to several accounts. Be it, Facebook, Twitter, etc.

I'm sure it's entirely possible to ask users for their Twitter login/password on your application. It's a very bad practice though, as OAuth avoids the need for client applications to ever touch a users credentials. I suggest setting up an authentication/authorization system that maintains a login/password and then allows connecting multiple OAuth accounts via an AuthenticationStrategy model or the like.
