How many Meta Quest headsets can be registered to one Meta account?

I need a definitive answer on account to device limits.

Use case: I am setting up a small training lab where up to 20 Meta Quest headsets are prepared and maintained under one Meta account for centralized purchases and quick provisioning through the Meta Horizon app. Before I scale, I want to be sure I am inside supported and documented limits.

Specific questions

1. What is the hard limit, if any, on the number of Meta Quest headsets that can be paired or registered to a single Meta account in the Meta Horizon app or backend?
2. If there is no fixed numeric cap, are there soft limits, security checks, or rate limits that might block additional pairings at scale?
3. Are there restrictions on simultaneous sign-ins across multiple headsets using the same account, for example forced sign-outs or throttling?
4. For apps purchased through that account, are there known concurrency limits on launching the same title on multiple headsets at the same time, and is this enforced globally or title by title?
5. For classrooms, clinics, or small business pilots, is there an official recommendation on whether to use one account for multiple devices vs separate accounts per device or user?
6. If an official Help Center or developer article already documents this, please share the link so I can follow the supported guidance.

What I have tried

• I have a few headsets registered under one account and everything pairs and updates correctly.
• I searched the Help Center and forum for device limit, pairing limit, multiple headsets per account, and did not find a clear numeric limit or policy.

Goal

I am looking for an answer that cites official documentation or a clear policy number. If the answer is “it depends,” please outline the practical ceiling and the recommended setup for 20 headsets so I can proceed without surprises.

Thanks in advance. 💙
