Not for sensitive accounts
Anything sent to a public inbox is visible to others. Do not use one for an account you care about, and never for account recovery.
OTPPin does not run a free number list or a public inbox. The only product is a private, paid one-time order. Here is how the two differ, so you can decide which you need.
A shared public inbox shows every message sent to its numbers to anyone who opens the page. A verification code sent there can be read, and used, by other people, and the same number is often seen by many users at once.
A private order is different: the number is assigned to your account when you place the order, and the messages it receives are shown in your dashboard or through your API key. It is a paid product, with the price shown before you confirm.

Registering costs nothing, but each order is paid for from your account balance. Balance top-ups are currently accepted by cryptocurrency only. The minimum top-up is $2.
One number, for one service, for one receiving window of 20 minutes. It is not a rental and cannot be reused after the order closes.
Pick a service and country in the dashboard and review the price before you place the order.
