# Signing in to Amazon Chime
<a name="sign-in"></a>

The steps in this section explain how to sign in to the Amazon Chime desktop client and web app. For information about signing in to the Amazon Chime mobile app, see [Signing in to the mobile app](mobile-sign-in.md), later in this guide.

To complete these steps, you must have a registered Amazon Chime user account, and you must use your account credentials.

**Note**  
You can join Amazon Chime meetings without a registered user account, or by using an alternate method of joining. For example, you can use the phone number in a meeting invitation to dial in to a meeting. However, when you do that, you go to the Waiting Room until an authorized attendee admits you. Once admitted, *you only join the meeting*. You have limited ways to participate in the meeting, and the rest of Amazon Chime, such as chat rooms, remains unavailable. For more information about joining meetings without an account, see [Joining a meeting](join-meetings.md), later in this guide.
