Account sharing is when more than one person uses a single membership login. One person pays, then shares the username and password with others who use the account without paying for their own.
Some sharing is harmless — a household using one account on a couple of devices. Some of it is lost revenue — a login passed around an office or a group chat.
Why it matters
For a paid membership, every shared login is potential revenue that didn’t happen: people who get the value without subscribing. A little sharing is normal and not worth fighting; widespread sharing can quietly cap your growth. The goal isn’t to punish legitimate use — it’s to keep casual password-passing from becoming the norm.
How to discourage it
The most common, least heavy-handed tool is a session limit — a cap on how many active logins (concurrent sessions) one account can have at the same time. Set it high enough that real members on a laptop and a phone are never inconvenienced, but low enough that a login shared across many people starts bumping into the limit.
How Members Only approaches it
Members Only includes a session limit setting that defines how many concurrent logins an account can have. It defaults to 2 — enough for a member’s computer and phone — and you can raise it, lower it for stricter control, or set it to 0 to disable limits entirely. It’s a deliberately simple, proportionate way to discourage casual account sharing without making life hard for genuine members.
