Block the same PRO account from logging in on multiple devices at the same time
A few people pooling money for one shared PRO account is the most common - and least visible - form of revenue leakage in online courses.

The system blocks PRO accounts from being logged in on multiple devices at the same time, and records those attempts so you can gauge how much account sharing is actually happening.
01
Highlights
The system prevents PRO accounts from logging in on multiple devices at the same time.
Helps significantly limit PRO account sharing, shared learning accounts and multiple people buying one account together.
If you own a mobile app, the system distinguishes between the mobile app and website, allowing login on both without being blocked.
The system records simultaneous multi-device login behavior to assess the level of account sharing.
Other security features such as IP registration, fingerprint authentication and face authentication are mostly unnecessary because they can bother all students just because a few people share accounts.

Frequently asked questions
Will a learner using both a phone and a laptop get blocked?
If you have a mobile app, the system distinguishes app from website, so they can be logged in on both without being blocked.
Why not use fingerprint or face verification instead?
Measures like IP registration, fingerprint or facial verification are largely unnecessary - they inconvenience every learner because of a small number of account sharers.
Does this apply to free learners?
Concurrent-login blocking applies to PRO accounts.
