Customer scoped access token limit

Few questions:

Is there a limit of how many customer scoped access tokens can be generated?
When a new customer scoped access token is generated does it invalidate the pervious active token?
Is there a way to list all active tokens a customer has active?

There is no limit.

No.

Is there a way to list all active tokens a customer has active?
Let me check on this.
