“Sign in to your Plex account” can be a bit of a loaded phrase, since it can be a little different, depending on whether it applies to your Plex Media Server(s), your devices, or the plex.tv website itself.
Signing in to your Plex account has multiple benefits, including:
- Help Plex apps locate and connect with your Plex Media Server
- Many Plex apps (such as PlayStation, Smart TVs, and Xbox) will only work when both the app and server are signed in
- Allows player apps to connect securely to a Plex Media Server that’s also signed in
- Make use of Plex Pass subscription features, if you’re a subscriber
- Access your server when away from home (if you’ve successfully enabled Remote Access for your server)
- Access shared content from family or friends
You’ll want to make sure that you sign in to your account in both the Plex Media Server and your various Plex apps.

Tip!: If you aren’t yet signed into your Server, you’ll usually need to first access it locally via http://localhost:32400/web or http://127.0.0.1:32400/web on the server’s computer.
Click the 
Settings button in the top bar and then select General under the server entry in the sidebar. If more than one Plex Media Server is present on the network, select the server in which you’re interested by using the dropdown on the left.
Under General on the left, if your Plex Media Server is not currently signed in, you can sign in using the Claim Server button.
You can sign in using Google, Facebook, Apple or your account username/email and password.
