WRONG. this was a YOU problem.
2FA was introduced in 2020 and there’s a whole entire Plex Support page dedicated in showing how to activate it to protect your self and your account from further danger.

You can ALSO have Plex account access tied to your Google and Apple accounts, and have no relationship to the Plex password.

Additionally you could use any online password generator to come up with a much better password than the one you have now.
Last but not least, it’s up to you to also do your own security maintenance/audit under the Authorized Devices tab. Check for ANY device that seems suspicious to you that may not be worthy of having access. If it’s a device that a family member or friend might have that you weren’t aware of, no need to be alarmed. It’s better they have to sign back in with their credentials again than have someone run amok with account.
When you do change your password, it is highly encouraged that you follow this step:
- You can optionally enable the Sign out connected devices after password change checkbox when resetting the password. That helps secure the Plex account by signing all your player apps and any Plex Media Server you ownout. You’ll then need to sign back in to your account in each app/server.
Tip!: If you do choose to “Sign out connected devices after password change” as part of your password reset, then you’ll need to sign in again to any player/client apps you use as well as any Plex Media Server you own. You’ll find information below on how to do so.
One more thing you can also do is assign yourself a PIN code to your account to add as a buffer and it doesn’t matter if you have managed users or not, assigning a Pin to your admin account has it’s advantages of further temporary blocking unauthorized access, especially from your server settings.

Protect via PIN code
Members of a Plex Home can have a PIN code set on their account. When set, it means that the code must be entered when switching to that account in a supported Plex App. For instance, parents may wish to put a PIN on their account so that their children can’t switch to the parent account.
It is always recommended that if you are the a server admin in a Plex Home that you set a PIN, else a user could switch to you and edit server settings.
