Merchant-key recovery

You may create 5 recovery sets per IP per UTC hour, begin 10 recoveries per IP per UTC hour, and make 10 confirmation attempts per IP and session per UTC hour. A prepared replacement expires after 15 minutes.

Create a fresh recovery set

Use the current merchant key. Eight one-time codes replace every older set and are shown once.

Replace a lost merchant key

The code is not consumed and the old key remains active until the replacement key is saved and exactly re-entered.
