You can allow your members to sign in to your community using their Twitter account.
To start the process, go to AdminCP -> System -> Login & Registration, click Create New to setup a new login method and choose Twitter. You will now be prompted to fill in some details which you'll need to acquire by creating an "app" with Twitter.
Before you are able to create a twitter application, you first need to get access to the twitter API. To do this, visit https://apps.twitter.com and sign in with your twitter account. If you click on create app, it will ask you to first apply for access to the API.
Click apply first of all. Once you have done this, you will be presented with the following screen, which you need to select "Doing something else" from the options.
Once you have selected the reason, you will be asked to confirm your details. Unless you have any pressing reason to do so, you should click next at the bottom of the page.
You will now be asked a series of questions related to the use of the API on your site. Here we will be filling in the "In your words" section at the top, and the "Do you plan to display tweets............outside of twitter?" section at the bottom. All other items should have "No" selected.
For the first item of "In your words" you need to enter something like the following screenshot.

Make sure you click Update Settings to save.
4. Go to the Permissions tab and click Edit. Ensure that Access is set to Read and Write, and then check the Request email addresses from users checkbox (it will not be checked by default). Make sure you click Update Settings to save.
